Yep, just connect to the +/- of the speaker wires and wire to your amp.

If your amp has speaker-level inputs, you don't need the LOC.

Thumbs up

The next step is to find the Bose amp underneath the trunk coverings on the driver's side. There are two harnesses that are running to the amp. The one you want is the blue harness. Remove that and identify your input wires:

Head Output Rear Right + Blue
Head Output Rear Right - Pink

Head Output Rear Left + Teal
Head Output Rear Left - Purple

Remote Wire Light Blue/ Silver

You need to be able to convert 18 gauge wires to an RCA jack to connect to the amp. One way was to get an RCA jack with a twisted pair of wires that you can cut and then splice. Another option is to get the JL line conversion that I used (pricey - $25, but I couldn't wait for mail-order). Splice them with in-line splicers available at Radio Shack and tape it up with electrical tape. You also want to splice into the Remote Wire for the amp. Although the JL amps have audio sensing power-on capability, it is unreliable (I found out the hard way) and I recommend using a direct remote power-on line.
Nice write up man! this will make it much easier for me! appreciate it

So i can just splice my rca from my sub amp and hook it right to the 6x9 speaker wire running into the speaker itself? What would i hook the amp remote wire to then?

Thanks in advance

Yes, provided your amp has speaker-level inputs. Just remember, you're at the mercy of the horrible EQ built into the bose amp if you're doing this.

As for the remote wire - from the post you quoted above:

Ty for the response. I have like 6 different amps,they all have multiple adjustments. So if i do it with the proper connector,instead of splicing the rca's, will the sound be better?

If you're using the signal from the bose headunit before the bose amp, it's a clean signal, with no horrible equalization, however, it's a balanced signal. If your amp takes a balanced signal, that's the optimal way to do it. Anything after the bose amp has been screwed with and will be a worse signal to send to your amp, but it's unbalanced at that point, so pretty much any amp can take it.

so does the rca converter plug in before or after?

An LOC splices in after the bose amp, but if you're using an amp that takes a balanced signal, you'll splice RCAs in before the bose amp.

I spliced my LOC in using the blue plug on the bose amp... it works fine, is this the right way or did i mess up?

Depends on the type of amp, really, but if it doesn't sound bad, then it's probably correct for the equipment you have.

The amp im using has unbalanced rcas... just want to make sure the car isnt going to start on fire or something haha. I can hear a little bit of unwanted noise with the volume real low, i dont know if grounding the LOC will help this at all or not though.

Loc is a line output converter...basically used for hooking an amp up using the high level signal from a factory deck and converting it to a low level signal
