ok i finally had gotten my sound system put in i could not figure out how to get it to work so i had it professionly done. Now 3 days later my car only starts certain times
all my electonics go on but sometimes teh car will not start do you think it could be the alternater, or maybe just the cold weather if it is the alternater how much do you think it would be to rebuild and modify so that it can handle the power

Actually capcitors don't make a big enough difference as to what they're advertised to. I run 1200 watts peak from my Kicker KX600.1, so i got a 2 farad cap, and my lights still dim a little. First- Test your alternator, see what it's putting out, you may have fried it. If your alt. is fine, move on to the "big 3". That is - the ground from your batt to the frame/chassis, the ground wire from the batt to the engine block, and the power wire from your alt to your battery. Upgrade these wires to one step up from what the power wire that your subwoofer amplifier gets. Since my amp takes 4 gauge, i would need to upgrade with 2 gauge. Here's a helpful thread from my dodge website, breaking the whole thing down, read down for more detailed instructions...http://www.dodgeintrepid.net/forums/showthread.php?s=&threadid=28585&highlight=big+three+wiring

a 2 farad cap should be able to handle in excess of 2000 watts if your lights are still dimming at 1200 watts something is wrong... i'd check your grounds or maybe your battery... as for starting your car, i would check all your wires for corrosion (alternator, starter, and battery)... and make sure your negative battery terminal is ok... i had the same problem in my car... pushed it two miles home in the rain and all i had to do was move the negative battery terminal to get a better connection and it started right up...

I thought the same thing about caps, but over time i've learned from the hard-core electrical engineers (i spoke at length with several highly qaulified people about this) They're kind of a band-aid fix more than they are a total fix.

i would look into that switch, but i would definitely start wiring up your underhood area, can't hurt either way, its only gonna take burden off of your electrical system, what's your alt rated at, like 90 amps?
