Subwoofers in a cruiser mopar

A couple of years ago I went down the slippery slope of hifi car stereos...multi amps, mids, tweeters, subs, DSP, acoustic tuning, sound insulation, etc. An enclosed 10 inch sub ie JL Audio will fit behind the front seat which was good enough for classic rock but won't do the sub intensive bass pounding new stuff. For that you're going to need bigger enclosures, dedicated amps and more power supply
