Here it goes...I have a 98 Honda civic EX with a stock 70 amp alt. I have bought my amp and subs (Powerbass asa1000.1d) and (2 12" Powerbass s-124d subs). I'm going to do the big 3, and I'm going to run either a Kinetik hc1400 or the Stinger battery that is rated for 1050 watts rms (I don't remember the model #) with 1/0 gauge wire, and an isolator. I don't want to spend $300-$500 on an alternator. Are there any bigger alternators out there that will bolt right up with no modifications from other make/model vehicles? And what problems will I have if I don't upgrade my alternator?
