Default Two DSP's

Hi All!

Apologies if this is in another thread, but is anyone running more than one DSP (as in one for the front, one for the rear). If so - do you get your source for the DSP's from the head unit (front RCA's go to Front DSP, rear RCA's go to rear DSP), or do you throw everything to the front DSP and use two channels from the front DSP to go to the rear DSP (sort of a daisy chain)? Thanks!

Why would you need to run more than 1 dsp? I think most have 6 or 8 channels out, don't they??

There are some cases when more than one DSP is needed, when many different types of speakers are being used. I have one in the shop now with 2 DSP's, but it has 2 large comp horns, 4 smaller comp horns, multiple bullet horns, 2 6.5s, 4 8's, 2 10's midbass and 2 12" subs. with 14,000w., and may add more.

One DSP is ran off the front channels, of the HU, the other DSP on the rear.

I could see needing 2 dsp's in those situations. I meant in normal situations. lol Most of us dont have 16+ speakers on a bike.

I have thought of a second DSP at times myself just because I love the Arc PSM and it only has six channels. I am running two amps and four speakers now and am sort of getting by with the rear four speakers on one tune and using the gains of the amp to sort of blend the volume between the lids and pods. I don't have room up front for a bigger unit than the PSM so was thinking of maybe getting a used second PSM and mounting it in the bag with the amp if I ever get a smaller amp.

The wiring channel going down the frame is overstuffed as it is so taking things to the next level by working in the rear of the bike is tempting.

Does your bike have the hole in the frame at either ends like mine does? I ran my amp and dsp power wires through the frame instead of down the backbone under the tank and seat.

Mine wasn't plugged.
Take the seat off and you should see the hole where the side rail of the frame comes down to the end of the take.

The other end is open right at the neck under the riser.

I'll see if I have pics of it.
