wat u guys think of this set up?

MB QUART RVF216 6.5 COMPONENT SPEAKERS running of a MA Audio M489I amp in a 98 honda civic? wuld that be enough power for them speakers are they good? opinions pleaz?. i have a 15" alphasonik sub right now in there running at 900watts rms and it makes my lights dim each time the bass hits shuld i get a seperate battery for the sound system? if so wich one

MB Quart is nice, that amp would power those components well.
have you done the big 3 yet? if not do that before getting another battery, but if you have an optima yellow/blue top would be my choice.

wat is "the big 3" mean?

look in the newbie thread ......

basically it helps current (power) flow from the battery to the stereo more efficiently
