my lights dim out wqhen my bass hits peak

[teck]

when my headlights are on and im listening to music loud all of my lights dim out when my bass hits peak power, i have 2 batteries in my car one for the cars electronics and the other one is for my system can any one help me out with this problem?

Your altenator is crapping out on you. Get a new one, upgraded one even. A lot of people get a capaciter (cap) instead which usually helps out too.

ALL the power in the car's electrical system comes from the alternator, once the car is turned on. That second battery is just an extra load on the poor alternator.

get a stronger alternator (or rewind), with some 3 main wire upgrade. after all that has been done and you still get the problem, a cap should be considered (with very LOW ESR).

id say get the high amp alternator first. i tried going for the easy fix with a 1farad cap. didnt seem to help a bit. sure looks nice though

You might want to upgrade your ground wires throughout your car, or at least the main ones on the car and the ones that deal with your sound system.

i already have a cap oh well i guess i have to put a new alternator. they are selling me a alternator from a v6 accord for 450 installed is that cheap?

[strodda]

do you know what the amp rating is?

Wow, slow down one min. How much wattage are you follwoing through your car. Beat mine and get an upgraded alt. I run stock alt, small ass honda bat. a one farad cap. Plus a viper d2500.1 which runs at about 2000 watts and a kenwood four channel amp that runs at 400 watts. The only time my headlight s dim is when i have been bumping a long time. You said you have have two bat. How are they wired? Do you have an isolator. Try a 1 or 2 farad cap to end the problem before spending major money to fix a small problem

a cap is useless unless you have with SUPER low ESR. if he's going to get that kind of cap, its going to cost him lots of $$$. the good ones are the ones made from brax/helix, and i forgot the other name.

Right, that is why my cap stopped my dimming problem and it has a slightly higher ESR then the good ones. Lighnting cap with digtal voltmeter for $110.

most cars need modifications to have 2 of them in. i know there is this one integra that has 2 alternators. talk about power robbing

I have seen systems that had a hydraulic driven spline that was spinning as many as 10 alternators.
