So i went a different route to preserve my stock amp and speakers.
I got a digital sound processor from panasonic CY-AC300EX.
I got the unit to work perfectly, with only one problem.
The volume isn't very high, at the highest level with all gains maximum.
It's just loud, but not blasting loud. I want it to be at least as loud as the stock unit. Any idea how i could do this?

 

unless there's some way that the dsp is actively attenuating the volume, maybe the unit just does that

 

i doubt that, at least i didn't see any functions that does that on the dsp anyway.
the dsp gives out 2 volts, i'm not sure what the bose unit takes, but i'm going to try software preamp increase first. Then if that doesn't work i'll try to do some kinda line driver. For line driver, is it better to put it before the dsp or after the dsp?

 

2 volts is not enough.

> 4 volts is required when running with the bose.

Line driver can go either way.

 

thats what i thought too.
if iwas to put line driver into the output i'd need 2 x stereo line drivers for the 4 channels. can anyone with experience with line drivers tell me if they lower the quality at all?
And i was searching for line converter, and some produces 8v rms, would that be too high for bose?

 

No they won't lower the quality as long as you get a good one that doesn't clip early.

You need something that is adustable.
