roblem:
I have an 03 tibby (and after replacing tranny and lower control arm starting to get disgruntled)
I have a Pioneer 3400ub aftermarket head unit that I've been wanting to hook up. I got my wiring harness for my Infinity sound system today, and after switching out the lca and changing oil I still had enough light left to switch out the stereos. However, after triple checking the wires, all I get is a very soft sound coming from my rear driver side speaker. I've checked to make sure the wires are right, And I have my blue/white striped wires hooked correctly (for the amp-I can hear it turn on through the speakers) I have read numerous things about sound not coming out at all or some other thing but that's not my problem. As I've said, sound comes from read driver speaker, just extremely softly, amp turn on IS hooked up, and wires are right. The only thing I can think of, which may be a stupid question, is whether or not I should use my RCA outputs to connect to my amp or not, Please let me know anyone, any advice would be welcome and appreciated, and I did check fuses and the speakers do work with stock head unit.
Also if anyone has any info on some good winter tires (not necessarily snow tires) that would also help me with my new tibby troubles. Thank You

i had a very similar problem when i installed my new speakers and head unit. Is your amp stock?
i would only hear faint sound from my rear speakers. i did not use direct RCA connection though
switching back to the stock radio and i still have the same results.
really made me wonder if the rear speakers were always just faint and i never noticed
anyway this problem is still killing me.lol

Yeah, Stock amp. My rear speakers work perfectly with the stock infinity head unit, it's just the aftermarket head that the only sound comes from the rear driver speaker.
Your problem to me (which might not be saying much) sounds more like a short in one of your speaker wires or along those lines of your front speakers work and your rear barely do. Might of interpreted your message wrong however. Thanks for the reply.

ah, i mis-understood your problem.
so sound only come from your rear speakers and faintly when the aftermarket HU is in?
if everything is fine with the stock radio then maybe the new radio has some problem? maybe the harness adapter?

Sorry, I wasn't quite clear still, All of my speakers work perfectly with my stock head unit, it's with my aftermarket that sound(what littles there is) only comes from just the rear driver speaker. I hooked up my blue/white wires and can clearly hear my amp turning on, it just seems like there's no sound coming from the amp.

I've searched YouTube/google quite a bit and all I've found is making sure to hook up the amp wire (blue/white) which I've done. I do have a currently unused solid blue wire and an orange wire, but I thought orange was illumination, and currently can't remember what the solid blue wire is for. Are you suggesting I might have the wrong wiring harness? And Also, I've already connected all wires possible to my Aftermarket wiring harness so where would the extra wires connect to? And should I not use my RCA hookupd then but use what's coming from the aftermarktet harness?

I would also like to add that I've looked at the wiring diagram and matched up the wires to be sure everything is correct. Any and all help is appreciated.
