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

 

They are out of phase.. either the left or right is backwards. For example..

LR + ---> LR +
LR - ---> LR -

RR + ---> RR-
RR - ---> RR+

double check everything.. if you're using rear speaker wires then RED & BLACK are your postives

 

I'm pretty sure I reversed the positives and negatives on the Scosche, but I could've overlooked that. Will give that a shot and report back.

Thanks Slody

 

cool.. yeah when one rca jack is plugged in and it sounds fine, but when both are in the sound pretty much disappears it's because something is out of phase.. what happens is the signal from say the left channel is fine, but the right channel will be reversed.. cancelling each other out basically.. so just disconnect one channel *right or left* and switch the + and - around.. and then your problem should go away.. if it's not that.. then it's your wiring on the subs.. are you running 2 seperate subs?

 

Running one sub, Audiobahn AW1000N. The sub itself was tricky wiring because it has 4 sets of +/- for setting the Ohms. The sub and amp are confirmed working fine in another car, so it's either the wiring in my car, or a defective LOC. Hopefully I'll get some time in the next few days to pull the dash and rewire the scosche.

Thanks again Slody.

 

cool.. yeah it's gonna be the wiring on that adapter then.. because i'm sure you're running a set of speaker wires to the sub and not one set per channel? at least you better lol...

 

Only one set of speaker wires from amp -> sub. Mono amp so it'd be kinda impossible to run two sets

 

haha good.. i've seen the worst so i've learned to expect everything



see what i mean?

 

All I can say to that is...WOW.

 

That's AWESOME!

 

I bet it knocked!
