New build remorse!

[ardvark666]

Hi everyone. I am new to the forum but hopefully this is the right place for good advice. I just built a system in a 2022 Super Duty and after months of planning a “budget” system I have some regrets of my DSP choice. I went with the Alpine DSP PXE 60. It only has 6 output channels and now I realize this is a problem. I have a mino sub amp and a 4 channel amp running the front and rears. Now I want to add a second amp to run the front full active and hit a snag. I have it connected to an AmP Pro and it uses the optical output (which I converted to coaxial). Should I use 1-4 output channels for the front speakers on the dsp and basically set the 5&6 as a pass through and send that signal to my rear coaxials and sub? I have audison amps that have rca outputs. 400.3 and 500.1. Sorry for the long question. Something tells me I am going to wind up with a dsp that has more outputs. My issue came down to budget and 400.00 was really pushing it for the dsp since I dropped probably 2 grand already on speakers and the interface and amps and sub. Unless someone knows of a dsp that isn’t crazy spendy. Any suggestions on my next step? And yea I have to keep the rear coaxials. I have kids that sit in the back and blah blah. I don’t love having them but we go on long trips so they have to stay.

Realistically you need a dsp with more channels

My other thought is to use the rear analog rca out on the pac unit and connect them to the rear speakers. I could tune the system without them and possibly just connect the rears at a low level just so they aren’t silent back there. Not sure if I will have a delay though. I guess I can try that and see. It’s a shame Alpine didn’t add one mono rca on this unit or allow for the input rca to be assignable to an output channel.

I would take a look at the Dayton 408 dsp. I have a buddy that swears by them.

That doesn't always work because the processed channels will be slightly delayed and the channels will sound out of sync. You need to invest in a dsp with more channels.

That’s kinda what I figured. I’ll keep the alpine and just mess with it to get it to a good spot. It’s better than no DSP at this point anyway. I would like more control but I can always manually attenuate the tweeters if I need to.

what speakers, amps etc you using?

Currently Audison amps 500.1 and 4.300 with kappa 90csx 6x9 component set. Pair of morel 6.5 rear and a single 10” alpine type R.
