SYS2 to SD2 problem
 
Ok. I have a problem. I bought a SD2 to replace my syn2. I swapped the two and have no power to the SD2. Couldn't figure it out so I swapped back to the syn2 and everything works again. It's running 4 rev10's.. I can't even get the SD2 to power up.


HELP

Did you check the fuses in the amp?

Yes. All good.

My only other suggestion (other than the amp may be bad) is to check your remote turn on lead. A few years back I had 3 Fosgate amps with the remote turn on leads wired straight to the head unit. Wouldn't turn the amps on. I then wired them through a relay and everything worked great.

Maybe this is where the problem is (forgive my ignorance I know almost nothing about electrical). My original setup was a syn6 to run the boat speakers and a syn2 to run the tower speakers. I added 2 additional Rev10's to the tower so I upgraded the syn2 to a SD2. The remote power wire is ran from the syn6 remote power to the syn2 remote power and works fine. Is that something I have to change with the SD2?

Not necessarily but that could be the issue. so if I am understanding you right, your remote turn on lead comes from the head unit to the SYN 6 and then is daisy chained over to the other amp? if so, try disconnecting the turn on lead from the 6 and run it over to the SD 2 by itself (leaving the SYN 6 unconnected)

then turn the system on and see If the amp turns on.

IMO the best way to handle the remote turn on leads in a multi amp system is to connect the remote lead coming off the head unit to a relay and then running off the relay over to the amps into a small distribution block and then feeding each amp with a separate lead off the dist block.

Ok. I'll try that when I get home. Thank you. What kind of relay are you talking about? Again I know just enough to get into trouble here lol. I do know what a distribution block it though...

Thanks again

Got it. It was a chassis fuse. Thanks for the help.
