I didn’t want to use the one out of the dsp for fear of overloading the circuit.
simple relay make short work of that. Amps turn/off together with no load to the source unit.

I also re-powered the factory Klipsch subs with a JL HD750/1 I had laying around to hear how they sounded with more power. My initial impression was louder and more full.

Like MLA said, a relay would work well.... although that is an extremely low draw circuit, and itís doubtful it would cause any issue.

How is the unwanted noise situation on your setup? Is there any?

In talking with JL, it sounds like the VX series amps are the key. They can easily accept the 8v signal the DSP is putting out, and can easily filter out unwanted noise. They donít have a Marine version yet, but if they are installed in a proper location, they should be fine.

Are your Klipsch amps powered from an isolation relay that is on all the time when the battery switch is on? It appears the way my boat is wired, whenever the battery switch is on, the DSP is on so I donít know if I can use the DSP amp turn-on circuit. Even with the stock amp setup, if I left the battery switch on for more than 3 days it would kill the battery.

The HD amps accept the 8V signal from the DSP fine. No noise as long as everything is grounded properly, same as other setups.

I saw ASA released a new DSP under the Polk Audio Marine name - looks to be the exact same as the Klipsch DSP manufactured by ASA.

https://www.asaelectronics.com/polk-...sp-module.html

It says it's compatible with Polk Audio Ultramarine amps. I think we'll be seeing more of these systems installed in other boat brands in the near future.

Below is the pinout of the DSP outputs as I have tested. I think that one of the channels of the subwoofer output is inverted so a speaker isn't blown if the DSP outputs are accidentally switched. (i.e. swap pins 4 & 6)

Mini Din female side
1- 12V trigger (not strong enough for my JL amp though)
2- 1V trigger (not sure what this does)
3- Left +
4- Right +
5- Left -
6- Right -

As I said previously this provides a 5.5Vrms output that can be used through a line output converter or directly into certain amps if they can handle that range (Most JL amps, some wetsounds amps, etc.)

I bought a couple 6 pin mini din cables (M-M) on amazon, cut them in half, and made adapters for the inputs to my amps.

Here are my finished RCA adapters for the amp inputs:



I used these RCAís from amazon
