I'm installing an aftermarket head unit and I have and aftermarket amp and subs and I have the head unit all wired up and when I got to test it only the sub works no speaker sound! How do you fix this ? Please help need done asap

 

I also have a loc I don't know what to do with that?! Please help

 

If you don't know what an LOC is, then you really shouldn't be installing your own HU, amp and subs.

A Line Output Converter is used to convert a head unit's speaker outputs or the outputs of an oem amp into a signal that will drive the preamp inputs of a new amp. If your amp has high level inputs, then you don't need an LOC.

 

Lol dude we need a LOT more detail than that. What kind of amp do you have? What kind of speakers? What kind of head unit? If it was "all wired up" then I wouldn't expect a problem lol.

Tell us more about your setup brah.

 

If you aren't getting sound from your speakers, maybe you do need the LOC.

 

I know what a loc is but I think I need to remove it to be able to get sound to my speakers. I'm not sure why they are not working. I have fusion sub with a built in amp to the sub, then I have Jensen 6.2 inch touchscreen head unit

 

Or need to figure out how to hook the loc to the new head unit

 

What are you using to amp the speakers?

 

I'm not sure , I thought it was was the loc, what shoul I be using to amp them?

 

Turn the factory amp on.

 

How do you turn on the factory amp?

 

Connect the amp turn on wire from the new radio to the amp turn on wire in the factory harness.

 

Ahhh it's so simple. I hope that's what it is.

 

I did but when I do that my sub does not work

 

do your speakers work? are you using a wiring diagram?

 

You have to connect the amp turn on from the radio to the turn on for both amps.
