Amp cuts off lights dim also

[godsmack29]

so ill be driving the time frame varies when it jsut decides to cutt out. but then i turn the radio off then on and i have bass. i dont get it. i thought it was my amp so i was messing with the ground as i read, but i for got to take the fuse out and now its in power protect and wont come out, so i got another little amp to just use for now, but thats still cutting out. also when i hit the brake my headlights dim, radio cuts out sometimes when i put on high beams, and the blinker and a/c dim all my lights. could this be the prob??

sounds like a short somewhere. Check the ground near the amp. Make sure it's tightly screwed. What's the amperage in fuse rating on the amp itself?? Some amps will have 2 40a or 1 80a or like mine has 4 30a, so the fuse that should be near the amp should be at or slightly above the fuse rating of the amp.

So like mine has 4 30a fuses. I have an ANL fuse holder with 1 150a fuse near the amp. I have a 140a ANL fuse 12" from the battery. My lights still dim but not as before since I got a new battery, but I'm seriously thinking of doing the 1st part of the Big 3 electrical upgrade. The Big 3 is just adding thicker power wire gauge to your factory wiring. The factory only puts about 6 or 8ga. What the Big 3 does is add like 1 or 0ga wiring. So the first step is to go from the battery negative to the body chassis...planning on putting either 1 or 0ga.

The dimming you're experiencing might also have to do with your battery. How old is it?? is it more than 3 years old?? You might want to try replacing the battery first. These corollas have puny alternators, so my dimming is due to these corollas only have 70a alternators. If it's too costly to do, you can try the Big 3 Upgrade, but sometimes you can find places that have a 120a or 150a alternator.

I was about to go the route of using a kinetik battery but then found out that they use 3/8 threads not bolts. So I'd have to cut my factory wiring to accomodate 3/8 battery terminal which isn't good if I ever need to just get a battery replacement. Then I'm SOL waiting for a kinetik battery to come in the mail to replace my failed one.

You could also try adding a kinetik or optima yellow top as a secondary battery to prevent lights dimming...you'd have to add a battery isolator as well

here is a brief explanation of what's involved with the Big 3 Upgrade:

my amp i have now just has a 25a in it with a 20a inline fuse, my vr3 400w amp had 2 20a still using the 20a inline fuse. my battery is out my totalled talon so its about a year old. but like i said 2 weeks ago i had no problem at all, then this all started all of a sudden. i was thinking about the alternator but i hear they are expensive, i need cheap solutions.

[gameguru1360]

then the Big 3 is what you want to do. That's the cheapest alternative to buying a bigger alternator or AGM battery such as a Kinetik or yellow top Optima.

If its going in to protection mode, 9 times out of 10 youre not getting a good ground. Thats always been my experience. In fact I just had the same problem with my prizm, cause I'm grounded to the trunk floor. Get a voltmeter and make sure you're getting a good ground to that amp.
