So i installed my Pioneer 4100 today and absolutely love it but when i went to hook up my amp for my subs and hooked up the remote wire no sound came out of the speakers and the amp did not turn on but i unplug the remote wire and i have sound but again no amp turn on obviously, i already have the remote wire running to the factory amp and tried to splice into it for the sub amp exactly like it is shown in the wiring instructions for the head unit... what should i do??????

Just to be sure, the amp hookup was as follows;

Power wire: from amp to battery
Ground wire: from amp to ground
Remote wire: from amp to receiver harness (blue wire)
RCA's: from amp to receiver
Speaker wire: from amp to subs


... is this accurate?

For some reason splicing into the remote wire that goes from the head unit to the factory amp caused the factory amp to lose power and obviously cannot send power to the factory speakers. Guessing not enough voltage running through that wire to power the factory amp and aftermarket amp when spliced - though it takes next to nothing to power up an amp via remote signal, so that still has me a bit confused.

Just run a new one from the harness to the amp and , voila, sub woofage! :p

I think the problem is you lose the remote wire for the factory amp (i.e. speakers cut out when removed), so keep that intact as it was before. Just run a new remote wire from the head unit's harness (skinny blue wire) to the amp. That should solve the problem.

Good call Scott. I would advise to stay away from those cheapy splicers as well. Go to Radioshak and get a terminal block. They are something like $2.88 for a 12-post block. That's what I used to tap into my signal wires - you can see a pic of it in my build log link in my sig. Connection is as solid as it gets.

i am using these for the connection


and i know i am not tapping into the power antenna lead because the factory amp turns on just fine and sound plays fine i haven't been able to check the wire itself yet since my wife has me running around all day during my vacation so hopefully tm but we'll see

So did you run a new remote wire yet? Or is that what you're doing tomorrow...?

Before you tear up the interior hiding the wire, do a test run with the wire just running from the front (CD player) to the rear (amp) just laying on top of the seats to see if this solves your problem.

Usually, process of elimination works very well when troubleshooting car audio issues,
