Hi I have 2 10' MTX TC510's subs and i am running them of the MTX amp tc3001. I want to upgrade so some people told me to get the MTX TC4001 amp and that should do it, but the car audio installer at future shop said with the size of my trunk(my car is a sunfire gt) i would get better sound with one quality 12', and if the 12' is the way to go which 12' is good quality??? The installer recommended an infinity perfect sub. what is everyone's opinion on this??? THanks all opinions will help!

 

Avoid big box stores and go to qualified local indepentant for starters. Secondly. the enclosure is actually more important than the subwoofer for sound quality(unless the sub is really poop). for best overall on a budget is 1 decent 12" sub. (alpine type-R, JL audio 12W3,) something middle end . mounted in a custom ported enclosure specifically for that sub. like 90% of "off the shelf" ported boxes are tuned to around 40hz. too high general listening.

 

Kicker L7's are good and affordable just dont over power them and they will be good...
