I am looking to upgrade my current setup. I have a Directed Audio D2400 pushing 2 Hifonics Brutus Subs in a ported pre-fab box. It was a pretty good setup, but now I want more. I have been looking at the AQ sdc2.5 15" woofer. I would want to power it with a Hifonics 1200D Brutus Series amp. Running it at 2 ohms, which would send about 900 rms to the sub. I researched, sub and amp is a little under $400 total . Is there any setup that is better than this for the price. They are going in the trunk of an 04 Grand Prix. Thanks Justin
