headlight dimming and dead battery

[gustavo_dibiase]

I just had a system installed about 3 weeks ago, and the 1st day running, my car wouldn't start and I had to get a boost... its happened about 7 times since then, but not every time. Also when I turn the stereo up to about 28, when the bass hits, the lights dim. The place where I got it installed said to not turn the subs past -3 until I get an extra battery but I've read, that's not going to solve my problem so should I upgrade my battery under the hood? Get a cap? Or get a ho alt? I have 2 bd1 15 inch audiopipe subs (800 watts rms) and a 1500.1 audiopipe amp and it's gain is only turned up half way... what should i do?

Start by setting the amp up right, make sure grounds are good.

^^^^then go on to the battery upgrades..as far as headlight dimming lighting is very sensitive to voltage drop.even a .2v drop will cause dimming in some cars...i have some serious electrical in my car and only thing that solved 100% dimming was hids

1500 is quite a bit for a stock car. Look into doing "the big three" also get an agm. Caps are a band aid.
