amps not drawing power?

I have dual profile amps, and I have no idea why they're not putting out.

I have 10.7v on the remote wire going back, 12.1 volts on the power. Grounds are fine. I'm getting .02v off of my rca cables, and .6 volts between the speaker terminals on the amps. So I know power is getting back there, and the amps are seeing it. All voltages were probed @the terminals on the amps.

Why would they not push anything through the subs? I can say these two things:

1) I had to splice my rca cable together for the right speaker (the left speaker's rca was fine).

2)Whenever I take off and put the rca cable back on, as the cable is going back into the hole, the subs do move, but once the cable is fully seated, nothing. This occurs on both sides.

EDIT: I measured the rca jacks off the headunit to ground, no cables involved. I got only .06 volts. Bad headunit?

10.7 V on the remote wire may not be enough to turn the amp on

if you wanna measure RCA voltage, you need to put the multimeter to measure AV volts, not DC

The amps do light up.

And I should be using AC? That explains a lot! You might've just saved me $130.

Also, my cousin thinks my rca cable is shorted out somewhere. We'll see...

yea, the signal from your cd player will be somewhat of an AC signal, definitely not DC. Oh, and if you have say 4 volt outputs .... you will NOT read 4 VAC on the RCA outputs.

I'm actually reading nothing as far as AC goes. I get readings with DC though. Maybe I'm hitting a bad ground when I go from jack to ground, I dunno :(

Yup, I verified my ground. It's fine. I'm still getting shit voltages off the rca jacks, but I am getting milliamp readings now (I'm using a different multimeter that's suffered less abuse). At around a pleasant volume, I read a fluctuating amperage of around 6mA, and it increased as the volume increased. I went back to the amp and measured the rca cord on the other end. Same reading, so the current is getting back to the amp.

Again, when I have the rca cord partially on the input jack on the amps, the subs move (I would assume from noise). However, after the cord is fully seated, nothing.

Any other ideas? I'm beginning to think there's gremlins or something and that it's not the headunit.

sounds like your preamp outlets might be shot.

Are you referring to the h/u? There is current coming out of the jacks and back to the amps.

you said you werent geting a voltage reading

Right, I'm not getting a decent voltage reading. Even with a new h/u. But I am getting current.

when you say you had to splice the leftt to the right rca did you use a y cable. also i will would have to check but wouldn't if the left and right rca both have the same signal cause it not play since it no is longer a/c just d/c.

No, I simply spliced the right rca cable together. The left side was untouched. The right side was broken apart so I just did a butt-connect. In any event, I'm still getting nothing from the left rca cable, but there is current and everything is fine as far as wiring is concerned.

I guess I have never taken voltage readins from my RCAs .... you do know you have to put a 1-10K Ohm resistor from shield to tip, otherwise no voltage with flow.

actully when i did mine it said .04 volt and was constant. so i firgured it meant 4 volts cause that is what my hu is rated for,

I guess I have never taken voltage readins from my RCAs .... you do know you have to put a 1-10K Ohm resistor from shield to tip, otherwise no voltage with flow.

Actually, no, I didn't.

I guess I'll eliminate the h/u as the culprit. Err, it's looking more and more like I blew both of my amps, at the same time :disappoin

I'll have to pull the subs out tomorrow to verify they're still connected inside the terminals.

There's something screwed with the RCA cables. When I plug them in, my headunit overheats and restarts constantly. The back of it burned my pinky :banghead:

When I disconnected the cables, everything went back to normal. I'm replacing them with monster rca cables this weekend.

you may have pinched and shorted them to the chassis somewhere. Be careful where you run them and try to protect them when routing thru bare metal openings.

My only question would be, how am I getting current back to the trunk if it's shorted out?

Things just don't make any sense @_@

shorts can still give off current. because shorts don't open the circuit.

It'd still show the same current coming off the rca jacks as it would at the end of the rca cable (all the way in the back of the trunk)?

:\

i got some junk rca cable lying around that came with my old amp kit if you want it.

I just went to walmart and picked up some junk rca cables. Hooked those up and the subs are working now.
