That amp will do fine, eventually you may want to get a one channel amp that does around 800-1000rms @ 1 ohm. I would ditch the cap and by a voltmeter (if you run into dimming problems or low voltage then you will need to buy a extra battery or bigger stock battery), you should be fine. what do u mean by "VOLTMETER" i was lookin @ a "BATCAP 800" if i switch out the cap for one of these will i be good even when i upgrade to a better amp.....ive been lookin @ a RF 1501bd the light colored one with the blue badge on top its an older model it says it does 750rms @ 4ohms i wanna stay @ 4 ohms cuz its cleaner and more controlled...right? thats what i was always told at my local shop and by family?
