This is why I asked if you replaced both amp/subs at the same time. The only thing really left is the wiring.

my guess is your remote lead is enough to turn the amp on. but not really turn it on. meter the lead. does it give you the same results as the power lead? If not problme solved.

That is a good thought N8 but wouldn't that be eliminated by jumping the connection?

I would think that if you did that already with a switch, you've re created your own remote, but if your'e still having the problems after that then it's more than just the remote wire. BTW, if not changing the head unit, I'd advise you running that switch off the ignition wire not the 12v constant just so you don't mistakenly leave it on and drain the battery.

Well its fixed. I'm not 100% sure what it was, but I replaced RCA's, remote, power wire fuse, sub wiring, moved ground

My buddy called me because him amp shut off.

I installed this small system EXCEPT the h/u

http://www.stevemeadedesigns.com/board/topic/168025-05-s2000-single-12-all-fiberglass/

So I take a look at all connections

Power- good

Ground- good

Fuses- good

Remote- wire is good but will not turn on amp

run new remote, still no turn on

jump remote to power, amp turns on

install switch to control amp power

Amp is on, sub connections good, sub doesn't play but pulses every few seconds

check coils- good

New amp, same model, same pulse problem

New sub, different model, same pulse problem

New RCA, same pulse problem

Disconnect RCA, use adapter to play music from my phone through RCA, same pulse problem

With music playing and amp on, disconnect sub wires and reconnect, split second of normal level and then drop to low and pulse.

Confused. Discuss please.

Can you explain the switch you installed? Specifically, where is the power coming from? Still the HU?

Not sure if this has been asked, I did skim through responses but didn't read thoroughly, but did you measure the voltage of your remote turn on?

My first guess is that your HU isn't putting out enough voltage. It's putting out some obviously, but not enough would be my guess. Could also be a bad ground.

I would try (one more time, I know you already did this) jumping the turn on from the power. If all is good to go again, what I would do is:

  1. Tell your friend to get a new H.U.
  2. If he says no, then run the remote turn on from either the fuse box or a wire under the steering column, whatever is best in that vehicle.
