I have the 7 speaker pioneer system and I was wondering If I had to take out the stock sub to put any different subs in??
Iput to JL 12's in but they dont hit or anything they just move up and down real slow.....
any suggestions?

 

When I first got my Cobalt, I had a pair of Infinity Perfect 10's, a box, and a Pioneer 800w amp for them from my Cadillac. I figured I'd give it a try. It wasn't that it was unsucessful by any means. It hit every single low note possible. Like, the stock sub hits most higher low notes. The Infinitys hit everything below that. It was cool. But at the time, it wasn't worth the extra weight or anything. So I sold them. But now I want them back for my Monte. But oh well. Maybe it was just how I had them wired? But then again, I've never dealt with a factory amp before. Maybe there were better ways to do it?

 

what kind of amp do you have pushing the new 12's?

 

go to http://www.woofersetc.com and look at the 10" subs. Pioneer has a new sub that will fit right in. It is the Pioneer TS-SW2541D. That is what I plan on doing. Plus all the rest will be Memphis mids and highs plus the Memphis Belle to push everything. And up front the Pioneer AVIC-N1 w/ navagation

 

just make sure you get a dvc 2 ohm woofer
