Amp shuts off ...again

[PENGUIN]

My amp shut off after i raise the bass up on the amp or on the stereo. Now I got an 500rms at 4 ohms kenwood amp powering two 15 cvrs. I could go all the way up and the mirror would almost fall off but then after a while the amp will shut off. I dont want to lower the bass on because I might as well put my 1200 watt max amp back on since it sounds about the same all the way up. Now the thing is that with this amp I have to turn the radio off and turn it back on to get the amp on again, with my other amp all I had to do was to lower the volume when that happened. What can I do to fix that problem. Do i need a bettter ground, battery, should I change the "the big three" cause I really want to hear my 15s!! thanks.

ps. my lights do dim a lot, and if I put the radio on (about half way) for about 5 minutes with the car shut off, the car will barely turn on.

You have a bad ground or one of you cables are not getting enough power, have you checked the main amp fuse?

yea its fine. Now I got two amps and the other never ever shuts off, but i don't know if because its only 600 watts. The two are connected to the same ground. I believe a bolt under the seat.

its too much power to the battery

SO what do i need a second battery or what? Im only pushing about 675rms... if that.

[92accordkidd]

You need a high voltage alternator. later

optima battery red top is a good battery

It sounds like your amp is getting too hot and going into protect mode. If this is the case, you're going to have to lower the gains on either your head unit or your amp. It also sounds like you have a current draw as well, which a new battery will only suffice for a while, a new alternator upgrade probably wouldn't hurt either

High current not voltage...don't want to mess his electrical up lol.

I'm going to say your amp is going into undervoltage protection. How old is your battery?

I have no idea how old it is, a guess would probably 8 years... since the stickers on the battery are all pealing. Im take it to autozone to get it checked... And I really do not want to lower the amp because if I do that it would be same as just having two damn tens and 600 watt amp! I want to hear what I paid for, in another car it worked all the way up..

What size wire do you have?
