Help on getting speakers to work properly

[jblaze05]

Hi everyone...Need some help here...This might be a little confusing but here goes. I have a Pioneer DEH-P4700MP head unit. Im using a 350.4 kicker amp to go to my front and rear speakers. I hooked up everything and i cant seem to get all 4 speakers to work properly. I can get the front ones to work and the rear wont or i can get the rear ones to work and the front wont. Just cant seem to get all of them working at the same time.I checked both of the rca cables and they are good. I also checked both amp 1 and amp 2 on the amp and they both work also. The speakers that dont play, you can faintly hear music coming out of them when you turn the volume up about 3/4. It seems bass plays at an ok level so it seems like i have no highs coming out of the speakers that arent playing at the time. I thought maybe it would of been a setting on the head unit so i checked that out but cant seem to find anything associated with it. If anyone can help be much appreciated. Thanks

That head unit has two RCA pre-outs, a full range pre-out, and a subwoofer pre-out. You are running your rear channel off the sub pre-out, which explains why you only hear faint bass coming out of it.

You need some RCA splitters so you can get a full range signal to both sides. Theyre like $2 a piece.

yep that sounds like it...i would recommend a x-over but dont think that it would go with your setup

Thanks alot....Cant believe I missed that....I just bought a Kicker 03KX3 3 way crossover so i will hook that i tomorrow. I plan on adding another amp later on this month along with some subs so i got this. For the power wire coming from the crossover....do i hook this up to the acc wire at the back of the head unit and does it matter if i run the remote wire from crossover to the same remote wire i hooked the amp up to (on the head unit)?

According to Pioneer's website, that deck has "Front/Rear" preamp outputs, not Front/Sub. Although I do know that a couple of their HU's allow you to change the settings in the HU to determine whether to use the rear output as a "rear output" or "sub output".

Yes...some of the Pioneer decks have that feature, including mine. If the bass is working fine, then there's a LPF activated somewhere.

I took another look at the settings and there was a lpf activated...setting "subwoofer" was turned on ...so thats why was getting bass in the back....but in the off position you can faintly hear the music so im not getting any highs at all back there it seems.

My bad guys...Gave the wrong info. The head unit is a 6700 version ...not a 4700...checked out the 6700 and its full range/sub ...so that is whats the problem..Thanks for your help.
