Help please.

07 Jeep Grand cherokee.

I just installed a Infinity Basslink into my new jeep, but I'm running into an issue. I have the Premium sound in my jeep aswell. I did a LOC, but I think it hooked up wrong. I hooked it up behind the radio (rear speakers). The sub volume stays consistent no matter what volume the radio is at. It eventually cancels out.

Do I have to hook up my LOC between the amp's output and the speakers? Also, should I wire them to the front door speakers instead?? I was reading those speakers are actualy the low range speakers. Thanks in advance.

Are you sure you wired it correctly with the correct POLARITY? Take a look at your work because it sounds like a simple fix. It doesn't matter what brand of speakers is installed in the rear.....even if there are no speakers there at all. The LOC is converting the signal from the headunit (to the speakers) to run your amp.

^^ basically. it doesent really matter if you splice it into the speakers or directly out of the hu. even if your jeep didnt have speakers, you could just splice the LOC into the existing wires

Figured out the sub cancelling, the phase was wrong on the amp, but I'm still having a volume issue. Even with the HU at 1, the sub plays at full tilt. Does anybody know if the output of the amp on a factory system is also volume control??

a lot of time they are. I would use some scotch lock connectors and try installing the LOC after the amp. most factory amps push about the same as an aftermarket headunit so it shouldn't be a big deal. try it.

on this particular vehicle you have to go on the output of the fact amp. the communication to the amp from the head is in a data format. fader balance and volume are done this way. Thats why when you replace the factory head you actually lose the fade. Go to the output of the amp and you will be good to go.

thats why you tap the wires before the stock amp not after

this car you have to do after the amp.

find them behind the deck

find them behind the deck

thats how he has them now and the vol is fixed. That is how these decks work. the signal out of the deck is fixed and the data control of the head makes the output of the amp attenuate.
