Good day to all!

It's my first post, so, do not be too rude on me!

Joke apart, I would like get your expertise to correctly split signal.

For now, I want to use the integrated DSP for the first year. Will see after.

I have two 6.5 two 6x9 two 8" and 1 12" and 3 amps.

2 pre amp will be used by 6.5's and 2 pre amp will be used by 6x9's.

Don't know what to do with the 2 mono pre out for the 3 subs?

Any help is welcome.

Thanks,

Stephane

Are you using 3 amps for the subs? What's amps are you using? We need more info for the bass set up. I can tell you that you may not need a dsp it's kind of overkill for this particular head unit. I have the dmx 1057 xr and it's a monster when it comes to the eq
 
Thanks KicktheSDbasshead for getting into my post.

My present setup is all in 2 ohm:
- Two (2) 6.5 in. and two (2) 6x9 in. are driven by a 4 channel amp. Old school Infinity Reference 7541a
- Two (2) 8 in. driven by a two (2) channel amp. Old Infinity Reference 311a
- One (1) 12 in. driven by a two (2) channel amp. (bridged) Old Infinity Reference 611a

Again, thanks KicktheSDbasshead for the heads up on a dedicated DSP not needed with this HU beast.

Thanks,

Stephane

Your 1st and second at RCA outputs goes to your 4 channel amp the last 2 which are already marked for subwoofer goes straight to your subwoofer amp which you are able to control from the head unit.
 
Unless you are running the subs in the front of the car with heavy dsp you really shouldn't run the 8s with a 12.

With enough dsp and front mounted subs you could run the 8s in an enclosure 50-100hz 6.5dup from there to 3khz, and instead of rear mounted 6x9s run a set of nice tweeters up front 3khz on up.

But again using 8s and a 12 mounted in different locations will cause phase issues and the frequency range of the 8s doesn't really line up well with a 12s bottom of range so they shouldn't share signal.

8inch subs in the doors might work but often don't and just cause rattles.

An 8inch midbass would likely work better and should be able to play 60-500hz without issue.

You really need 8 channels of dsp (tweeter,mid,midbass,subs) 10 if you want to keep the rear fill and to ditch the subs in the doors. I'd also ditch the rear speakers all they do is pull the sound stage rearward.
