Hi guys, i had a 600 watts 4 channel kenwood amp with 2 CompVR 12" (150 rms for each sub), now i will buy the new RF P6001BD (300rms for each sub), the system will be a lot louder? this is a good amp for that kicker subs?. I will extra buy a rockford capacitor for the dimming lights in my car. 1 farad will be ok?. thx
