wire isnt hot,

[silver187]

i have a 89 silverado halfton, its been for a while and im int he middle of restoring it.
im changing out the stereo and putting in a jensen vm9312 and i took the old amp out and its all connected, but it wont turn on, where does the power wire go to, so i can see if its a dead line or not?

make sure you have the remote wire from your deck hooked up and get a meter to test the fuse or just look at it under the hood for the positive wire.

if its simply a sub amp then you should have 5 wires hooked up to it.

pos and neg for power, remote turn on, and pos and neg to sub..

thats it

I agree, sounds like the remote turn on isn't connected or the power fuse is blown. Your power wire should go directly from your battery to the amp with a fuse within 18" of the batter.

Most amps usually have a power LED that comes on when the amp has power, does yours? Make sure your gains arn't turned all the way down, set them about 1/2.

If you really want to test the amp and your sure your RCA, power and you have a good ground. You could take a 9v batter to power up the RTO input of the amp and that SHOULD fire it up as long as everything else is correct. I say should because I've never tried this, but in theory it should work.

Let me know how it work.

I know this has a few additional devices in it but the idea is the same.
