I drive an '05 Liberty. Currently running 2 12" RF Power HX2 on an alpine mrx-m240. Hertz 6.5" up front on some old 4 channel RF amp bridged to 2 channel. Stock speakers in the rear running off of deck power. Deck is an eclipse cd5030.
My wife drives a liberty that I put two RF Punch HX2s in. XS D3400 under hood, 3100 in back. Older IA 40.1 for sub stage. Alpine components running off stock hu. I set it up as a stock class SPL vehicle. Bass stage sounds like garb bc it's tuned low 40s peaks at 51Hz. Clamped 2100 rising to 1.4 ohms did a 151 legal.
Wife isn't too happy that I just one day started running zero gauge all through her car haha
