I found a good deal on a couple subs with enclosure.

* Peak Power Handling: 800 Watts
* Impedance: Dual 4 Ohm
* Diameter: 10 Inch

i don't really know a lot about those subs, a buddy of mine had a set of PG 12's (not sure which models they where but they had 3 led's around the logo in the center) and he was really happy with them and they sounded good.

The only thing that i would be concerned with is back a while ago when we sold that model amp, is we could never get them to run @ 1 ohm, they did say that they where 1 ohm stable but every time we tried it (driving either a pair of Alpine Type R's or Rockford P3's) they would only play for about 5-10 minutes before they would blow the fuse. we tried a couple of defferent amp thinking that it was just a defective amp but they all operated the same. out of four different systems only one of the systems worked with out any problems, the rest of the time we just had to take a ton of money off of either the Alpine or Rockford 1000's for the package, so i dont know if there was just a bad batch of them or if there was a mistake on the specs and it was supposed to only be 2 ohm stable, but needless to say we didn't try to sell many more of them to see if the problem was ever fixed.

Another bit of info. My current setup is a single 12" sub. Directed Audio SX12D4. dual 4 ohm voice coil, wired to 2 ohm. 1200W max, 600w RMS. In a vented enclosure.

I would probably just try to get a second Directed, a slightly bigger amp, and stick with a ported box

pektel
October 21st, 2009, 02:48 PM
The box is a freebie, I just have to pay 35 bucks to ship it.

But these probably won't be better? I was going to sell what I have, and put these in the trunk. Really what I liked about these is they would fit completely under the rear shelf.

I don't want to buy a bigger amp, just was thinking about switching the sub/box out.

the audio store i go to used to sell phoenix gold stuff. pretty quality stuff they have. the only bad thing ive ever experianced with them was their amps. ive been through 2 of them in a pretty short period of time. i say pick em up. 10s are the way to go of you are going to be getting anything imo. i love the accuracy of them.

Andrizzle
October 21st, 2009, 05:35 PM
Eh.... TBH any major car audio buffs would tell you not to get those subs. You can get some real nice underground brands for a little more.

But if you are wanting something to just toss in there and hook up to your amp I can see that being a decent deal. But I would never own PG subwoofers... or amps...

gixxer
October 21st, 2009, 06:49 PM
dont do it.... good price but you get what you pay for. and your amp will not run at 1ohm. for 145 you can probly find something alot better. remember 2 is not always better than 1. you can probly find 2 10inch jl w0s for that price. the new ones hit hard but are not a good sq sub. i run all hertz so thats what i recommend. im very happy. you can probly get a dieci 12 for thjat price that will sound better.

October 22nd, 2009, 12:50 AM
pete dont do it!... i my opinion if you want something thats gonna take a beating and keep on ticking look elsewhere...

i have two 12" kicker CVX's in my LS and they are amazing! I first had two 12'' Alpine type-x subs n blew 'em up - but the kickers take everything ive thrown at them. For power I have 2 alpine v12 amps (one for ea. sub) wired at 4 Ohm's pushin' 750w RMS / 1500w peak to ea. sub in a 1.0 sealed enclosure. Let me tell you they pound!:eek: ...and they are sealed! If they were ported (or vented/bandpass whatever) id probably need a new car by now. (and yes i have the whole trunk dynamated)

The 12''s fit nicely under the rear deck but if you want 10"s they should provide plenty of power - actually one 12" CVX in a ported box would probably be more than enough.

your actually in luck as Amazon is offering all kicker stuff on sale now...the subs are ridiculously cheap. $119.99 ea. for the 10" subs with free shipping!:eek: ask anybody thats crazy! they r usually like $250+ ea.

here are the links for 10" 2ohm and 4ohm

let me ask you questions that will help in your qwest for new subs.
1: wat type of music do you listen to most?
2:are you more of a sound quality guy or a bass guy?
3: wat type of head unit and speakers are you running besides subs

pektel
October 22nd, 2009, 10:29 AM
Head unit: Kenwood Excelon DDX7015:
http://i161.photobucket.com/albums/t228/pektel/hufull.jpg

Door speakers are eclipse something-or-others. 5x7 components, with the tweeter mounted up higher in the drawer:

http://i161.photobucket.com/albums/t228/pektel/tweeter.jpg

I would prefer sound quality to over-powering bass. I like it to be balanced.

But if I want to listen to something bass heavy (i.e. Nelly's "Pimp Juice" lol), I really want the bass to rumble.

pektel
October 22nd, 2009, 11:29 AM
Here is the sub/enclosure I have now. It's just a generic enclosure.

Pek, is there something with your bass' sound now that you're not happy with? The reason I ask is that I'm going to be putting a single Kicker 12" Solobaric w/ Kicker Vented enclosure in mine, and am wondering if I'll end up in the same spot you are.

Nah, it's fine the way it is. I just thought if it was an excellent deal, then I would buy it. I haven't been looking for anything else, it just sort of fell into my lap.

gixxer
October 22nd, 2009, 01:29 PM
not a bad setup but maybe just do a custom box for your 12 that meets its specs. and add dynamat. belive it or not it not only stops rattles but increases sound quality and decibels.

pektel
October 22nd, 2009, 01:32 PM
I think I would really prefer a sealed enclosure for more accuracy. I tried to purchase a 36sf pack of dynamat extreme from krys ( a member here) for 150, but she never got back to me. Guess I'll have to try somewhere else.

Thanks for the tips!

i must disagree. you can get a high quality sub amp for alot less than 600. just cuz it cost a certain amount doesnt make it bad or good. and the pheonix gold titanium amps were badass but that line isnt available anymore beings that pheonix gold sold there name to a cheap a$$ company.

ive had sound quality cars and an spl car. ive hit 159.6 db with 4 12's and scored 18 out of 20 on a real time analyzer in usac comps. i know a thing or 2. not sure if they do the same usac stuff anymore that was 10 years ago. i worked for a high end custom shop much like unique up until a few years ago i moved to home audio install

i was just ranting about the lower quality car audio ive been exposed to in recent times. i look for stuff from like 1997 or so. im old school when amps could do a fraction of an ohm. 50 watt high current amps were like $800 but could run 4 subs and draw like 150amps. lol

like i said it was 10 years ago.i was a part of "team xtreme". i used the original Orion Xtr dual voicecoil 12's. 4 of them in a small sealed enclosure firing up into another enclosure that was angled forward and sealed all around except the front. it was bolted down and the top was braced with 2x4s cuz it would crack the mdf. powered by a Orion 250 hcca at 1/2 ohm mono. also had another 250 hcca running mb quart 3way components up front (8",4", tweet). old skool kenwood ps905 cd, orion 300psw line driver preamp, and an audiocontrol 30 band eq. 160 amp alternator and deep cycle battery. it was at the dash with the windows half way down. car was covered in dynamat, cracks were filled with expanding foam to make it good and solid. using good ole bass mechanik at about 55-60hz. my amps were "rated" at 50 watts per channel. i would win my class and overall spl usually. i was only in high school my friends ran Pro Audio here in STL they gave me product and advice i did all my installs, looked nice but not all cool like u see pros do, but i was young. all in my first car that was a 1987 cavalier baby.....sweet

before and after from when i was 15 to when i was 18. lol whats funny is people really thought that car was awesome back then
http://i188.photobucket.com/albums/z85/XxbmxlsxX/cavalier.jpg

a friend of mine todd waters had a walk thru mazda with same box design, 6 xtr 15's, just 2- 225 hcca amps, 12 batteries. he went to world finals in 97 and hit 167.3db with the mic near the rearview mirror. the original orion stuff was sick then they sold out to go mainstream and took a dump. spl doesnt really tell you how "loud" the system is. i had been in the pro audio van with 12-12's in a wall right behind you. it hurt but only did 153db. the key was sealing everything so the waves all went forward at eye level and making the car as solid as possible as to not absorb the vibrations and mounting the box solid to the car for stiffness. at least thats what i think

thats a good sub right there. take your rear deck sub off that way some sound can pass thru the openings. this way youll still be able to put some stuff in the trunk. dynamat the trunk make sure the license plate cant rattle also. should sound real good and clean

that boston is known as the egg. in the right enclosure its loud. one of the loudest ive heard but as far as sq it simly isnt for that. i would definatly suggest the jl. make sure the box is done right and it will blow you away. and in the future upgrade your amp when you have the cash and it will sound twice as good.

well ill take pics tomarrow of what im describing if need be but i cut the locations where the stock 6x9s go out and wrapped some 6x9 grills i had laying around in tan grill cloth and secured them over the holes. then i took that piece where the arm rest folds down and cut a square out of it then wrapped it in grill cloth and replaced it. now there is nothing stopping the sound from my trunk from coming into the cabin. it sounds like im driving all the time with my rear seats down, but without the ugliness and seats are still useable. if you want pics just let me know. and you would need a real custom box if you wanna port it threw the decklid because if you dont do it just right the port will cancel out the subwoofer and it will just sound gross. put your seats down and listen to ur music and if you like the output do the steps i described above and you will be satisfied"for awhile as there is never enough"

Okay first:

Do NOT buy from dealercostaudio. google their name and you will get hundreds of hits of scamming and complaints.

Secondly: That W7 is overpriced ludacris. JL has nice stuff, W7 included, but it is not worth what you pay, 400 dollars on a mainstream 10"? puh lease.

I would take an underground company for half that price and get hell of a lot more out of my money. It sounds like you're not really looking to upgrade to a nice system just yet, but when you are, you should check out some of the real car audio buff's forums: www.caraudio.com and www.ecoustics.com are both nice sites where alot of people will help you out. I started my car audio hobby @ Ecoustics in the forum's subwoofer forum and have been an audio head ever since. The place is great as it is not too cluttered with garbage, like caraudio.com.

I'm going to add dynamat to the inside of my trunk.
Subs keep popping the trunk lid open.
I like the old school rockford amps.
They're small in size put out lots of power and sound 10% better than say my kenwood 500 watt I have in my Camaro.
I built a custom 3.7 cu/ft box that also holds the amps and cap.
It's big but because it's slanted, it has a minimal loss of trunk space.
The RF 1000 watt mono amp toasted my audiobahns so for 350.00 shipped I got a pair of Cadence single 4 ohm coil 35lb subs that can easily handle 1000 watts continuous rms each at 2 ohms.
I,ve added 4 12 volt computer fans on metal brackets to cool my setup.
I can control the 4 amps levels and eq's from the dash and mix it up however I want it.
I like having the old school 3 way setup with an extra amp to power the Bass Shakers under the seats.

October 24th, 2009, 09:54 AM
Is it wise to run 4 ohm subs at a 2 ohm load?

How is the SQ?

October 24th, 2009, 10:41 AM
And gixxerboi, I really may think about doing something to open up to the cabin by way of the rear shelf. My son's car seat sits in the center in the back seat (the safest place in a collision), so I wouldn't be able to use that area behind the arm rest to my advantage.

I'm thinking maybe cutting the holes, then reupholstering the rear shelf, with a couple supports or something. Don't know if I want to use speaker grilles in the rear shelf.

04SCTLS, I just read a suggestion yesterday about your trunk issue. Adjust your latch so it closes tighter. I believe the post I read said you can adjust it about 1/8". Should do the trick.

Ha Ha
That was me in the other thread saying you can tighten the latch 1/8 inch.
Even after tightening it down the 1/8 inch it's still poping open after 10-15 min of play so I can:

1. take the top latch out and ovalize the holes then remount it canted to one side so the hook is more curved around the pin if you follow me.

2. Take the bottom latch out and ovalize those holes so it closes even further.

3. Get some Home Depot 1/4 inch weatherstrip on a roll and apply it to the underside of the trunklid where it meets the gasket.

I think I'm going to do the first one because I suspect the latch is slipping past the pin because of the pounding.

Here's the link for the Cadences

Is it wise to run 4 ohm subs at a 2 ohm load?



2 4 ohm single coil speakers in parallel are 2 ohms.

The Rockford 1000.1 is rated a conservative 1000 watts rms at 2 ohms.
Most subs are 2 4 ohm coils so if you parallel them you get 2 ohms.
This is fine for running a single sub.

But if you have 2 of them you get 1 ohm in parallel or 4 ohms in series.
I had my Audiobahns at 1 ohm and they toasted.

My EQ and crossover add another 12-15 db so I'm putting out lots more than 1000 rms, probably 12-1300.
I specifically bought speakers with single 4 ohm coils rated to take 1000 watts rms each so they would be 2 ohms resistance in parallel for the amp.

I needed a pair and didn't want to spend 400 for 1.

I also considered these Hifonics that can be hooked up as a pair at 2 ohms.

hey 04SCTLS

what kind of brackets did you use to hold your box down?

I used hardware store gate locks.
The ones that have the eye that can be turned.
That all that holds the box in place.

This is the thread about building my box.

Those cheapies match these.

I hooked them up 1 coil per side for 2 ohms and found out I was putting out more than the 500 rms per speaker.
Well 1 set of coils are still good :D

Those Sonances are great pektal.

Glad you found an underground brand to look into rather than the mainstream overpriced junk.

thoughts?

A Sonance.v2 would be great.

And RD is a good company.
