Spent about 4 hours installing and tapping into the stupid wires, and im pretty much ready to send it in to pro's.

Basically, i've tapped into the wires properly using the OP's help (I tapped into the rear LEFT and RIGHT sub's). I do however how the Remote cable from my aftermarket amp lying around as I have no clue where that's supposed to go... But from the Hi/Low Converter I did use the Remote cable from there and tapped into the "thin black wire" from the factory amp's harness.

I'm not sure if that could be the problem or not. Also, I tried to old amp's that I had laying around, neither would send a signal to the Subwoofer. Maybe I just need a new amp?

Any help would be appreciated. And i'll try and post some pics up tomorrow in the day time.
I'm not sure if I follow exactly what you're trying to say? But if you don't have a proper switched power source running to your remote input on your amp, then your amp shouldn't be powering up. So you definitely won't have a functioning sub in that case. For my remote power source I used a fuse tap behind the glove box, and ran a piece of wire all the way to the trunk from that. But if you already hacked into a remote sopurce off your amp harness for the LOC, then you might as well just tap some wire in there to run to the amp for your remote source to the amp.

Did you unplug the connector from the stock amp while you were trying to tap wires? If you didn't seat that correctly that could be why none of your speakers work now. I can't think of another reason why your speakers would suddenly stop working?

We are assuming here that you have a correct power and ground ran to the amp from the battery as well.

I'll be in Mission around the 10-15 of November if you still haven't got it sorted out. Might be able to take a quick look when I'm there.

So i read this whole forum and im still confused. To install the amp and sub i need a Hi lo converter for my stock stereo. Ive also been reading that i need to tap into the black remote wire so my amp can power on and off. What have you guys done for this? i know i can buy the trigger online for the sub but im looking to install the amp and sub today and need to find a store with the loc and trigger. Do line out converters have built in triggers, or could i just intstall the hi lo converter and be done? Im looking on amazon and i see the stinger SGN141 line out converter with remote. Is that all i need?
