Line Out Converter Help needed- which harness wires to tap?

The lc7i does not require a remote wire to power itself on. I'm not sure why you quoted me.

 

Thank you!

 

ok I need help here with AudioControl LC7 questions (if anyone here is using it in their system). I'll see if I can best explain my scenario here. I just built a new box, added new subs and a new amp and to me they were not sounded that great nor getting as loud as I felt they should be capable of doing so this evening I spent over an hour playing with it all and this is what I found.

I have the metra harnesses off my oem head unit connected to a speedwire cable. I (originally) had the white & grey wire going into main input on the LC7 and the green & purple wires going to the channel 2 input on the LC7. I then had the main output & channel 2 rca's going to my 4 channel and channel 3 rca's going to my sub amp. I have all the dials at 12 o'clock. This configuration did not sound good to me at all

What I did next is unplugged all the rca's and then plugged the rca's that went to sub amp into Channel 2 output and got the same results - the subs did not sound good. I then took those same rca's and plugged them into the main output and that is when I the subs shined. They sound great, they are loud and everything I want. So I thought here what I would do is keep the sub amp on the main output and then I used a Y adapter on Channel 2 output to go to the 4 channel (yes I know I lose fade controls). Everything sounded great, but then I noticed that the voice navigation from the head unit was no longer audible which I found real strange. To confirm my findings I put the 4 channel rca's back to the Main output and the voice navigation was audible again.

So what I did to get me going for now until I can figure it out is that I have 2 Y adapters coming out the Main output of the LC7 - 1 Y adapter goes to the 4 channel amp & the other goes to the sub amp and currently I have voice navigation from my head unit, all doors and subs sound great. Obviously I didn't want to spend all this money on the LC7 just to use 1 output

Anyone have any ideas why the subs sound like crap if I use the Channel 2 or 3 outputs? One thing I learned through this is that the voice navigation from the head unit only comes out the front speaker wires

I am baffled to all this and it very well could be a bad LC7, but I can't return it now since it's been past 30 days with Amazon.

Thanks everyone

(sorry for double posting, but wanted to grab a little more audience)

 

I have a 2nd gen with the JBL system and adding an additional 8" JL sub/amp.

What wire did you use for the remote to the new amp?

 

Alright, I got my Metras, my LOC, and everything ready to splice up to get output to a sub amp as far as I can tell


The final question: Where do I splice the LOC power in?
"Amp turn on" seems to scream availability, but that wire is also free in the rear speaker part too???


So 12v constant is always tempting (gotta love that yellow-yellow coding) buuuutt.....

any pointers??

 

For my LOC, I used a distribution block for power because I have 2 amps - so I have 1 power wire going to each amp and a power wire going to my LOC

 

For LOC "power in" you can hook it to the trucks "accessory wire" (white w/green strip under the dash, left of the steering wheel, above and in front of the fuse box). I have the JBL system and wasn't able to locate a remote wire so I hooked the blue remote wire to the "accessory wire" also and added a switch (just in case i'm driving with the stereo off).

 

I have an lc7 and have front HU signal to front speakers and rear for rear and sub. Then I take the sub output directly to the amp. No y splitters.
