Power surging

[Enduro800]

This has been happening sporadically, but more so in the winter. When I back up, or the traction control comes on its like there's a power surge trough my amp. Its hard to describe the sound, but it comes through the speakers and I think it either finally blew my sub or a fuse (its been too cold to check). The positive is directly on the battery and the ground is on the rear seat post (I sanded it all to bare metal and painted over it). Any help??

I have the positive wire on my amp and sub wired through a mini-ANL fuse holder with a 60A fuse for just such an occaison.

I also have my amp and sub grounded to a post under the front passenger seat. Grounding to an aluminum chasis isn't ideal. I used ground loop isolators coming straight out of the head unit on all pre-amp outputs to eliminate the alternator whine I was hearing.

I have the fuse and ground loop isolator too. The only thing I can change is to put the ground where you did.

If your sub is hooked up to a fuse it shouldn't be blown from a power surge. The fuse would be blown, and your sub wouldn't be on. If your sub is blown it's more than likely blown from the gain being turned up too high. Do you have an internally powered sub? Or do you have an amp hooked up to the sub externally?

What kind of sub do you have?

 

[red/green hawk]

Do you have the sub hooked up to channel 5? It's a 500w channel. Do you have the other channels hooked up to factory speakers?

 

[Enduro800]

Yes the others are hooked up to fronts and sound bar. Sub is a Fosgate slim 10" dealer checked that it worked with the amp
