Bose with aftermarket Headunit
 

Trying to get better sound form my stock Bose sound system with Kenwood DNX5220BT. The issue is, that couldn't set bass output. Is possible to get wired Bose sub with connecting to sw outputs?

The real problem is the bose part, the stock HU is not too bad, but the speakers and amp in the bose system suck.
If i'm getting the questions right, you can switch the rear RCA's to sub and use that, and just disconnect the rear speakers.

Ya I am not real clear on the question either.

Maybe this would help?

Also, agreed on even if you change the head unit your not really going to get much better sound. If you use the bose adapter which has rca's to accept your new head units pre outs you should be fine with getting your bose sub to work.

Yes, already read this. And many thanks for nice write up. Do you have pics or link for that adapter? Know just that installed with 4 RCA connectors - one set for rear and one for front.

Is any 6RCA adapter to BOSE or wire up SW differently. Already read about seperate amp cor SW.

Yes the bose adapter only have 2 sets of rca's which is how bose has their system setup only with using a factory harness instead of rca's.

There is not much you can do in the terms of taking control of the sub from the head unit.

If I understand to this diagram which I'm thankful to you http://www.the370z.com/audio-video/7...iagrams-2.html

The Bose Amp has 5 channels and stock HU is also have 5 channel output (never used stock HU) and Bose adapter use just 4 channels (rear speakers with sub).

And anything like MTX-re-Q5 can help?

The sub output is actually split FROM the 1st bose amp and goes to the sub amp.

So by using a re-q you only have to tap the front speakers to get a full signal. The req is only going to help you if you want to add new amps and speakers to your system. If you are already running a new head unit you can bypass the entire bose amp and run your new speakers from the new head unit.
