Dude turning on my wipers loads my alternator, do you think the alternator and "12 D-Cell batteries" battery canwithstand the drain from two 12" woofers?

 

what are u talking a about "12 D-Cell batteries" I am talking about the cars battere

 

I ran a 1500WRMS amp (on my sub) plus a 250 WRMS (on mids/highs) without too much "problems" other than lights dimming.. It is really all relative though. some amps are MUCH more efficient than others ( meaning, they will produce more power to your speakers while drawing less poser from your electrical system) I eventually burned out my alternator, and had it rebuilt a lot stronger ( stock was 60A, rebuilt to 114A) Anyways, its really tough to tell you what is the largest wattage amp you can put in your stock electrical system, There are many classes of amps, some much more efficient than others. (Class A, B, A/B, D, T.) Class T is one of the most efficient from what I understand, however, from what I hear, they lack "*****" meaning they are kinda on the weak side, compared to other amps at the same rated power (some amps will do well over their RMS rated power)
I hope this helps a little, if nothing else, I hope it helps you realize why you got no response before.

im running 1200 rms and can barely turn it up half way without the lights dimming and the speakers sounding like CRAP.
i think i need a big capacitor

 

i had a 1400 watt x class and it dimmed my lights in my civic, the alternater never went bad or the stock battery, and the capacitor didn't help much at all.

 

yes it dead so do u think I can put a poweracoustik 620max 300rms amp to the alternater
