Ok I ran 0 gauge wiring for my saz-2500. I put a 250 amp inline fuse and as soon as I connected the negative terminal the inline fuse blew. So I pulled out the wiring to make sure it wasnt cut went it went through the firewall and disconnected the amp. Ran the wire outside the car without the amp connected and the fuse didn't blow. Connected the amp and the fuse blew once I connected the neg terminal. Faulty amp or am I missing something? Amp was a refurbished purchased from db-r.com. Any ideas I'd appreciate it.

Are you sure you're inserting the power and ground in the correct terminals on the amp?

Yes sir

Found it the wire got pinched between the backseat. Thanks though

Glad you got it figured out.

Appreciate your input. I did check to make sure after you said it.

So the wire was being pinched enough that it shorted out that is crazy glad you fixed it though and happy bumping

Happy bumping, what kind of vehicle is this?

I bet that was a helluva spark!!
