I was originally going to use my 06 12" XXX (which wouldve had awesome lows) but I couldnt afford to run it, so I traded it for these. Now im kinda regretting it......Maybe I just need to find a single 15 that can get uber low off 1200 wrms. I tried everything possible today except for a new box, and still not nice lows. so oh well, I guess it will do unitl I get my new vehicle. Then its time for the 4 15"s //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
