The subs hit hard and everything is sonically correct. The amps get very hot, which is a concern, and they suck a LOT of power. I'm running 2 yellow tops with an isolator and I still have problems with lights dimming.
sounds like you need a capacitor
a .5 Farad capacitor for systems up to 500 watts
a 1 Farad capacitor for systems up to 1,000 watts
a 2 Farad capacitor for systems up to 2,000 watts
