Well I know it just makes the car heavier, and I'm probably too old but I couldn't pass up the deal. 120 bucks for two subs all the wiring a cap and an amp. Ive never heard of the amp brand but the subs are kicker comps. I wired it in to the factory speakers by splicin up some rca cables. And it actually sounds good. The amp is an auto tek 1000 watt. has anyone heard of this. And no its not stolen an ex employee was desperate to pay his snap on bill. I'll have pics tomorrow.
