Scosche SLC4 LOC Help

[anarche]

Hello Everyone,

I recently purchased a Scosche SLC4 LOC to give my stock HU (base model) pre-amps. After splicing into the harness for RR and RL and hooking up the scosche I'm getting surprisingly good results. However I'm running into an issue I hope someone here can address.

I'm unable to hook both RCA's running out of the LOC to my amp. With only RR hooked up I get perfect sound, with only RL hooked up I get perfect sound. However when I hook both up to the amp, I lose about 80% of the power.

I've double checked the splices into the harness, and every other component in the system I'm unable to diagnose this problem. It seems to me that because RR or RL work fine by themselves all my wiring is fine.

If anyone could offer some insight on what else I could try to troubleshoot this, please let me know.

Thanks,

AnarchE

Is the switch in the right position as well?

You want the wiring diagram for the scosche?

Yes it is, double and triple checked it.

I wish I could be of more assistance, I have one of those exact LOC's. I ended up going with a new HU so I didn't/don't need it. How far is Lancaster from Washington DC? Haha, I would give you mine to see if maybe it was faulty unit.

I ran into the same problems when I tried putting one of these into a friends Scion, we figured it was a bad unit, so we took it back to the store and got a new one. That problem went away but we ended up with different problems. He got pissed at the unit and smashed it, then just bought a real headunit that had the preout's. We both believe it's just a faulty unit, so you might wanna try a different one of just get a better radio.

Funny thing about that is, I also have a Scion (2008 xB). I have a feeling it's a faulty unit, I already did an RMA with crutchfield and I'm waiting on the replacement. Hopefully that solves my problem.

Will update this post if it doesn't. Thanks to everyone for the suggestions.

sounds like the ur crossing wires when u hook up both side so make sure the polarity is wired correctly on both sides

The polarity in the rear doors matches up with the scosche, however I've read in multiple places that by the time it gets from the rear door to the harness the colors switch. I'll be giving that a try the next chance I get.

Will report back.
