Amp will not power on, but I get +12v at power source

 

Unregistered guest
First of all let me say that I have NO clue about sterio's and Amps, and such. A buddy of mine game me some box speakers for my truck, and this 250-amp.

I saw that it required +12-volts so I ran a volt meter and found that my sterio has +12-volts when I touch both the Ground and Ignition wires. So I spliced into the Ignition and Ground for the sterio and ran it to the Amp. I am using 10-Guage wire, and both power runs are about 3-feet.

I heard that you should keep the ground wire as short as possible, and I may try that tonight, but I am getting +12-volts at the amp power connectors. I am not getting any lights on the amp though, aka power light is not coming on.

I hooked the RCA connectors to the sterio and amp up, and still no lights and no sound. I put a volt meter on the RCA connectors while the sterio was on, and I just got a 0-volts reading. I would have figured that I would see some kind of voltage.

Anyways, I am lost and I don't want to pay too much money to get it installed since I am sure I just did something stupid and one of you guys here will probably figure it out in no time.

Thanks for the help

You need to hook up the remote turn on lead on your amp to the remote on your head unit. Oh and its not a good idea to run your power off the same wire as your h/u. You'd be better off running that 10 guage wire directly to your your battery with a fuse within say 18" or so of the positive terminal. Ground your amp as close as possible to a point on the chassis.

I looked at my head unit, and it doesn't have a remote. It does have a Power Antenna, an Ignition, and a Battery hook up.

I will put the +12 to the battery, and make a new ground, but where should I put the remote connection since I dont have one on the head unit?

Thanks for the quick help.

Oh, and one more thing, will I need to fuse the remote connection as well?

Use the ignition wire that will give you remote power and u dont need to fuse that wire

Or the power antenna wire will be fine.

just to be safe he should fuse the wire in case the amp is unsafe

Use the power antenna wire.

Back in the day not many h/u's had "remote" wires. We always just used the power antenna out when wiring an amp.
