(centre or rear) was there a performance effect or a descent note change??? Link to comment Share on other sites More sharing options...

Take the end res off first 4 a sound sample of how it is with 1 b4 making your decision. Link to comment Share on other sites More sharing options...

I basically said he can have hia way with it so, so be it. Link to comment Share on other sites More sharing options...

My thoughts are a 4inch system with your power chase. Good luck.... Link to comment Share on other sites More sharing options...
