if your amp doesn't have a subsonic filter, you don't need to buy a new amp just to get a ssf. they make these things called f-mods that plug into the rca's leading into your amp. you just get the frequency you want, say 30 hz. and make sure it's a high pass 30 hz. and you are set. they run about $30 at http://www.crutchfield.com or http://www.thezeb.com. what is your box tuned to?
