In my experience, what you can find at your local Best Buy/Audio shop is good enough for the average Joe.

Which alpine amp do you have hooked up?
is the sound quality ok since u are getting the signal after it leaves the bose amp?

I have since upgraded to a Z2, but the sound quality was by no means poor. I'm running a alpine mrp-m500 pushing a 12" Type R. On the stock deck, I had the bass set at -4 and the gain on the amp was about 1/4 of the way up, and it was hitting HARD. Border line too much lol. That being due to the fact that there is no separate sub volume control like you have on many aftermarket decks.

To be honest, for the 2 months I was on the stock stereo, I would spend most of my time with the setting at -6(or whatever all the way down is, don't remember) and at normal listening level like volume 6-12, it provided PLENTY of thump in the trunk. I'm not the one you hear knocking down the street rattling windows and lamp shades. To me that's too much, but I was VERY happy with the sound quality that was actually coming out the sub, as well as the amount of sound that was coming out. I wouldn't hesitate doing it again or recomending someone to invest the money to add an aftermarket sub to the stock system.

You can grab the signal off any speaker output at the stock bose amp.

You're looking for a white/violet wire. If you need parts, shoot me a PM, I can get them for you.

I ran mine from the cigarette lighter fuse to the remote turn on.

That works too, just make sure that cig lighter doesn't have power while the car is off otherwise it will drain your battery

WooHoo, 100th post!

09 sedan with 10"kicker SB L5. What is the magic trick to stop the third brake light from rattling. A piece of cardboard under the headliner worked on my last car??

That or grab a sheet of dynamat for speakers


About the only thing I have found these kits useful for is to stop 3rd brake lights, licence plate, small plastic panels from rattling. They don't do squat for actual speakers lol.

From this part:
Pull the black sheath back and look for the green wire with the white stripe. That's the amp turn on wire. Take the blue wire that came with the amp kit and connect it to that wire. This is what is going to be turning your aftermarket amp on. Now plug everything back into the amp.
This may be a stupid question, but I'm just confirming that you can't actually cut your amp power wire (green one), but rather you need to splice your blue amp remote power wire FROM this wire. Is that correct?

I'm guessing the stock amp powers every other speaker in the car. If that's not the case, I guess it doesn't matter - just not sure if the OEM configuration relies on amp power for the speakers in the car other than the original sub. Can anyone confirm?

I'm going to do this tomorrow or Sunday. Good times.

Yes, just splice the remote turn on wire to that green wire. If you cut it, none of the interior speakers will turn on

Followed this walk through to a T but I can't get the sub to come on. I bought an "open item" LOC from BestBuy and I'm wondering if it's bad. Gonna go pick up another one today, but here's where I am:
I have power to the amp
When I unplug the RCAs from the LOC to the amp and just plug in an IPOD directly to the amp (w/ midi to RCA cable), the sub works.

I'm thinking it's a bad LOC.
anyone have any suggestions of other things to check before I go pick up another LOC?

Take a look in the end of the LOC, there should be 2 recessed plastic screws that you can adjust. Give them a spin to see if you get anything. Alot of times people mess with those and either break them or have the signal real low.(even then you should get a little something out of it.) Being that you hooked up an ipod directly, chances are that the LOC is

LOC was bad. Swapped a new one in and everything works perfectly. Bass = 0 at the headunit and amp gain barely cracked - all the bump I'd ever want.

Now for some reason my car won't stay on when I start it w/o giving it a little gas. Wonder if that's an ecu thing since I had the battery disconnected for several hours yesterday.
