So I'm about to buy some subs and have been looking around for a few days and have settled on the Pioneer Champion PRO Subs. i will have 2 12's in a ported box in an 04 Trailblazer. i don't want to use the whole back but still want the air space to power the subs. I want to stick with some well known brands no Sundown,DC, and all that stuff. I have heard great things about them just want to stick with a well known brand. Any other suggestions?
