Id go with the ssd's.. i had a single 12" fi ssd and an audiopipe 1500d and hit a 142 db. the ssd was great in every option. it killed the lows, hit the highs, and sounded clear as hell. i would recommend it to anyone. plus, their cheap =]
Give audacity a try. It is free and you can slow down music, add bass, and much more. You can download it using this link, http://audacity.sourceforge.net/
