: What do I splice/how do I add a powered subwoofer to BOSE hu?

I'm wondering what to get myself for Christmas, and one of the things I'm looking at is an Infinity Basslink 200W powered subwoofer.

If I go all out and buy this subwoofer to add some kick to the lows (not to blast the neighborhood), is it easy to install? Ideally I'd spice one of the wires at the rear speaker level but maybe I'm dreaming and it's not that easy.

What kind of kit would I have to buy or is everything needed included?

Also, I know you guys know the BOSE hu pretty well. If it matters, for the record my car has Onstar installed but not activated (in case that means I have a different harness).

Thanks in advance for some clear direction!

real easy
buy an rca adpater which connects off your rear speak terminals and gives you a sound signal
then run your wires power ground and remote for the amp
connect everything up and there you go!

Thanks!

That model has a audio sensor turn on, so all you need is power and ground.

Holy moly. Is that one so expensive because it reduces power too?

It's my impression that the Bose hu does not power the speakers. Each speaker has its own amp. Can I splice the line BEFORE the amp, and then make my own RCA output with say RadioShack parts?

Maybe you could u make me one, Jason?

you dont want one that reduces power
trust me
that one is ridiculous
i got one a circuit city for 20 bucks and connected it after the bose amps so it received the bose amped power
connecting it before the amp ridiculously reduced the power that came from them....

Thanks, heavymetals. SO it does reduce or "attenuate" power, AFTER the amp.

I wonder what the line that feeds the audio signal from the headunit to the individual Amps in the Bose rear speakers looks like. SOunds like splicing that should work, one for the left side, and one for the right side, both feeding into the powered subwoofer.

I appreciate that!

The "problem" with the BOSE unit is that the crossover and signal conditioning is all done in one box.
There are no line level outputs available.
Here is a link to the box/connectors:

I added a Basslink to my 02 Eldorado BOSE system and mounted in trunk, Works great. I pigbacked onto the rear speakers and used this as speaker (High Level) input to the basslink. Because Bose keeps the amps "alive" even when the car is off it requires you run the enable line from the Basslink to a switched 12 vdc source thats hot when the ignition is "on" or "acc". I was lucky on my Eldo cause it has a whole electronis shelf and fuse pannel behind rear seat so I tapped into it there.

Hopes this helps
