What does my stereo have?

[2002 LS V8]

I just recently purchased (last week) a 2002 LS V8 and am thinking about upgrading the stereo. For a few days the system sounded really good and the bass was suprising. Since then the quality has gone down and I am thinking that maybe the speakers are paper. Are there different trim levels of the LS V8? If so how can you figure out which one you have?

The stereo that I have is the Apline 6cd in-dash cd changer. Can someone tell me what size speakers I have, their location, and quality? I'm thinking about puting my old headunit in from my previous car (Pioneer AVH-P6500DVD). Would you guys suggest putting this in? Will I lose any functionality of anything else in the car if this is installed?

I know this one long, but any help would be greatly appreciated!

I've been reading the forums and I am still a bit confused. Is the stereo I have the audiophile system? If so are the speakers paper? I can tell that there are some speakers in the rear deck. What kind of speakers are those? What size? I have a lot of vibration back there, should I replace them or look for what is causing the vibration.

Thanks for any help you can give.

Don't replace the head unit if you want to keep the controls on the stearing wheel.

there is an adapter for the steering wheel controls, the deh6500 is a descent model, better then that factory hu you have.. I would put it in.. I had the 6400 and the 7500, 6400 being 3 yrs old or so and it was a lot better then the stock setup.. Lets you adjust a lot of things..
