I have the Pioneer 3100 DVD. I did the DVD bypass using a Bosh relay, which involves using the remote wire off the H/U. Can I still splice into the remote wire for the amp remote turn on. Also when I add my second amp down the road, can I splice into the remote turn on wire at the amp board for the second amp?

 

yes and yes.

 

Yes, though you may want to use a relay for that, too. In other words, remote wire activates relay that provides power directly from the battery.

 

Your best bet would be to use a relay. I'm sure you won't encounter any problems running your bypass and two amps on the REM+, but I personally wouldn't chance it.

 

quick question for you guys. i put a dual xdvd9131 headunit it my 03' and for some odd reason it doesnt have a remote turn on wire. i dont know much about stereos but what else could i hook my amps remote turn on to? thanks

 

yes it does. its the blue/white wire

i know it says that in my manual but there isnt a blue and white wire coming out of the back of the hu

 

The only other option you have is splicing a wire in to your ignition wire (or the red wire) and connecting that to the amplifier. The suggestion for that would be to use a relay.

 

alright well thanks for the help
