DIY: Upgrade Component Speakers from BOSE

Silly Rabbit

I have the bose with nav. If I want to add a sub and keep the rest factory. Not replacing speakers and not clipping any lines to the bose amp. Will this work?

-Add amp with power, fuse and ground
-Tap white line before bose amp and connect to remote in on sub amp
-Tap (4) L/R line-in lines before bose amp
- Connect tapped lines to LOC
- Connect RCA lines from LOC to sub amp
- Connect sub amp to subwoofer


Can a simpler passive LOC like THIS be used?


Edit - Some more reading and I get the idea that I want to use a LC2i and connect it using the sky blue and violet lines (9&14) coming out of the bose amp instead of the lines going into the amp. Correct?

Confused - Now I'm reading that it is better to use the red and green lines (hi-level) from the bose sub amp to the bose sub, it will provide a better feed than the blue and violet lines (low level).

Your original idea should work. I would splice the signal lines into the amp, that way you are tapping the signal from the head unit before the bose components come into play with their weird ohmage.

-2009 Bose w/ Nav-

Tapped wires before bose amp for LOC.

Installed two amps, one for sub, and another for a set of additional component speakers.

Everything went smooth, but now for some reason, when Remote Switch On is connected my factory bose speakers work 10% of the time. But added components always work. When i disconnect Remote Switch On for amps, factory bose system works fine.

Any help/tips would be greatly appreciated!
