Car Audio Amp issue

[mbalbritton]

I picked up an amp for my jeep. One of these, but not from Sears. I wired up everything but it's not working.

I checked resistance on my wires coming from the Jeep. 12.8V. I checked resistance on the inline fuse on the amp and the fuse is good.

The amp has a black, red, and a blue wire for power. black of course is ground, red is hot and the blue is for a power switch. Since I'm wiring through the ignition side of my solenoid, I just ran the red and the blue together. When I test resistance across the ground and power wires from the amp, my meter gives me a very brief reading then goes away. It's never the same reading either.

any thoughts?

I would hook red to battery with in line fuse then hook blue(remote turn on) to back of radio,if after market radio should be blue wire or antenna wire(it turns on amp when radio turned on) that's just few things I would do plus make sure have good ground and as short as you can get it.

No head unit in my Jeep, so no hooking blue to the head unit. my ground is about 6" long. I have even carried the amp to the battery and touched it off directly to the battery posts just to see if it would power up. nothing.

In sure you've checked the amp fuses if it has some

It's a Pyle. Literally and figuratively. They have a high percentage of DOA equipment. Exchange it and try again. Your troubleshooting terminology is somewhat wrong, but your readings are right. +12v on the red and blue, ground the black, hook a source up to the input and crank it up. Something should come out if it works. If it doesn't, it's likely a dud.

Oh, and don't forget to hook up some speakers! It may need all 4 connected to turn on.

I ran the blue to a tougle switch but I don't see why what your doing would not work I also had to a just the gain on my cray Pyle amp with a small screen driver before it would work

I hope your not checking resistance on on a live circuit.

Nope. But I will admit I'm an electrical idiot. It's always baffled me for some reason. I know enough to be dangerous.

Weds night I can help you at the shop if you would like. I have a spare amp we can try if you like....

Correct. My volt reading was 12.8, not my resistance. Thanks.
