Okay I'm trying to install my system in my sig today. I ran a neg. And positive run of wire from my hood battery to my back battery. I then ran a serperate ground for my amp and the power from the back battery. When I plug it in the amp starts smoking bad... its really pissing me off idk what I'm doing wrong. I really hope I didn't screw my amp up. I still had the neg. on the under hood battery disconnected just in case. Please help

once the smoke is let out, it can not go back in

got them hooked up backwards?

When you just plug the power in? No subs or RCAs? Is the amp casing touching the metal chassis? Polarity problems?

Edit: Generally when it smokes, it's fried.

So you have 2 grounds? Positve to positve then amp and neg to neg plus amp to body?

Grim's post confuses me.

Are you saying you ran a positive and ground from your front to your back batt, then connected the positive of that batt to the amp, and then hooked the amp neg to chassis ground, and not the batt neg?

What's the difference in Snoop Dogg and Bobby32's amp?

Nothing. We all expect them to be smoking at some point.

I have pos to pos and neg to neg wires from the hood battery to the back battery. Then pos of the back battery to power on the amp. Then I ground the amp to chassis. Smoke pours out of the amp

why ground to chassis? used amp? sounds like it was toast when you started, or you hooked it up backwards.

So you disconnected the run of wire connecting the batteries...but then directly connected the amp to the back batt?

 

[MakeshiftAudio 10+ year member]

Connect the neg of the amp to the neg of the battery. The amp is probably fried, but that connection is not optimal.

just double and triple check your connections... only advice i can give

by now, the magic smoke has been released, and the amp should be given a proper burial

Its fried. Atleast u get a new amp

The fact that smoke continues to pour out of it confuses me. It makes me thing the SMPS transformer is shorting.

His last post had him touching wires together in order to get sound out of the sub. I'm gonna go with that.
