I would suggest testing the output voltage on your alternator you currently have. Also check the amperage. Face facts, if you arent making enough amps for the power you are drawing, its time for an upgraded alternator, this will set you back about 400-600. Stinger, Ohio Generator are quality names. You should have 2 1farad stiffening caps, golden rule is 1 cap per 1000 watts. Put a red top optima at the alternator, you should not need more than this. If you need more power, then put a yellow top deep cycle in the rear. Go to a quality shop for installations, with this amperage the chance of major damage and or fire is real. Mad Marks of Bradenton is a very credible shop with great product. Good Luck www.madmarks.com

There's your problem right there. I'm surprised it's just your lights dimming and not your car turning completley off. You should be able to pick up a high output alternator at most good auto parts stores. Probably can find one a little cheaper online though, search. It would be highley recommended to uprgrade to a red top and atleast 4 guage wiring (from your new alternator to your new battery, and battery ground) at the same time. You'll more than likely notice your system is louder and/or cleaner as well with this upgrade. A battery alone just won't cut it, and I see capacitors as nothing more than a band-aid.

well it dose almost shut off when im idoling the rpms drop to almost 0 and the car almost stalls out. so what amprage alternator should i be lookin for or whatever? and also still not quite clear if a yellow or red top battery would be better. whatare the differances?

i would first up grade your power wire from ur battery to ur altenator if that doesnt work, second battery with a isolator, if that doesnt work bigger altenator.

Capacitors are useless, just a great marketing scheme.

the second battery is only useful if youre playing with the car off. and for the price of two yellow tops and isolator, he could have a new alternator, and be sure to cover the problem

does upgrading the power wire from the alt to the battery really make that much of a difference

I had a yellow top in my old explorer with a 1500.1 hifonics amp and 400 watt 2 chan hifonics amp and it ran great. The only thing is at nite there was a slight headlight dim when the bass hit full blast, other than that I had no probs

It depends on the car. I've seen cars with 10 guage wire from the alternator and a battery the size of a lawn tractors from factory...that's obviously not going to cut it if you're running a 500+ watt amp with 4 guage wiring.

well I am about to run a red top (cant afford a yellow this time around). Stock wiring from alt to batt looks around 8 guage with thick strands, not really flexable. What do you reccomend?

I'd go with 4 guage from your battery to your alternator, and also your battery ground to your chassis. It's usually a good idea to run atleast the same guage as your amp's wire.

yeah I run 2 seperate 4 guage wires for each of my amps. Looks like I am upgrading my alt to batt wire also, thanks

I have 4 guage from my alt to battery, I wanted to go 0 but I didnt have a terminal with 2 0 in/out.

Ill be getting a 200 Amp from Can Am Motors on Florida Ave in tampa, once i get $400ish. Nobody makes one for my car but theyll make one in kit form for almost any car.

you are right on that, but before i do anything i would still upgrade that little power wire from the alt. to the battery to a 4 gauge wire first
