It sounds like your batteries aren't connected together right? Have you load tested them seperately while there is nothing hooked to them? What batteries are they? Also, you have two wires coming off the alt...1 to your second batt and the stock to your original batt?

um i fixed the radio problem.... the starting battery went dead today and is shot..... so i replaced it with a Newer one and all the headunit problems and the highs not working are gone WOOHOO.... butt the subs cutting out is the final issue i have to solve......

it takes about 15-20 minutes of continuious running for the subs/amp to quit.. then it comes back on for about 10-15 seconds and goes off. repeatedly....and the amp gets really hot

ON TO ANSWERS...

i have 2 wires coming off the alternator

amp batt. Everstart maxx

starting batt. powervolt

Try running a wire from your neg post on both batteries to connect their grounds. They will still power things seperately, but will share their ground. Make it whatever gauge your power wire is.

how will this help........ just curious

how to do u have ur subs wireD?

what are the specs on subs and amp.

sounds like u have to low of a ohm load and its going into protect/

by the way, that sony is a peice of ****

 

[ado 10+ year member]

You may be getting ground loops since you are running two "seperate" batteries. It may not solve it, and like mentioned above, Are you running at proper ohm load?

I doubt a sony xplod 1500w amp can power 2 rockford p3's adequately. Though with xplod amps it will probably die soon anyways, from what I've seen, they don't last long.

I don't know if this is what youre saying, but it should look like this:

Since both of your amps are turning off, it is some sort of electrical issue.

I think he has them running 1 ohm and that is why the amp is cutting out.

It would explain the sub amp, and its a good possibility. Wonder why the other is doing it too?

Because that Sony amp is about 50% efficient (at best) and is drawing so much amperage.

 

[jeremy.vaughn 10+ year member]

the subs are wired exactly like that. except where they connect to the amp, i twisted the 2 pos. and the 2 neg togeather and they are bridged.

I only have ONE amp......lol

and the highs are still off and click randomly

ITS DRIVING ME CRAZY!!!!!
