Hello everyone. As you can see this is my first post – just signed up this afternoon as I am in desperate search for some help. Any and all input is greatly appreciated. My sig shows the equipment that I am running. I am 99% sure my wiring is good – 4 gauge ofc to each amp (2 runs, yes 1 1/0 would be cleaner but this was put together in two phases), 4 gauge from bat neg to grounding point of amps, all connections tight, etc. I also set gains with a voltmeter, understand the physics behind car audio etc…ive been in the “DIY” scene for 18 years.

Phase 1 consisted of the dsr, components, 900/5 and 1 sub. Everything working perfect just wanted a little more bass.

Phase 2 has been a nightmare. Adding 2 more 10’s and a JL hd750. I have double and triple checked everything, tried a different amp, etc. Basically it sounds awesome until I turn the volume up. Granted its turned up past a comfortable listening level for a nonbasshead…but no clipping, still sounds amazing until both of my amps turn off and turn back on. They continue to do so until I back off the volume or turn the bass knob down a little.

I had initially thought I bought a bad amp (the 750 was an ebay purchase and it is a little beat up) but now I am thinking otherwise. While waiting on the 750 I hooked up a slash 250/1 to test it out (if you solve my issue you can have it). Same thing happened – at high volume the amps would kick off and back on. At this point I went through and double checked all of my wiring, added the ground from the battery to the cab, tightened all connections between wires and at the amp. My 750 arrived at the same time so I never put the 250 back in.

It dawned on me today when it cut off and back on (I had thought I found the issue and was really let down by this…) that my dsr1 was actually cutting on and off. I came to this conclusion because I was connected to it via Bluetooth and when it happened I was no longer connected. Additionally, BOTH amps would turn off and on. Neither amp goes into protect – they both turn off and turn back on – light is green, then no light, then green flashes (normal when jl amps turn on), then solid green again. They also both pick right back up and when the bass hits it does it again.

Stranger thing is I tried to repeat it in my garage with the truck off just running on battery power. I figured if it was a voltage drop that the dsr1 didn’t like that it would be quicker/easier to diagnose if I am on battery power. I could not get the amps to turn off. Normally it would turn off between 18-22 vol level…I got to 25 and played the songs that would normally cause an issue and it performed flawlessly.

I contacted RF support to see if its a reported issue with the dsr but he was just as stumped as I.

The only thing that I can think is my 750 isn’t mounted anywhere – I never really made it through the testing phase so I haven’t mounted it. Its secure but I have it in the underseat compartment where it has plenty of airflow. I didn’t mention before that when this happens nothing is hot…the amps are barely even warm and the wiring isn’t warm at all.

I am sure there are some details I may have left out but I am hoping that there’s somebody that experienced something similar either with the f150, dsr1, or hd750 so I can wrap this up and stop taking my kids carseats out everyday to try and troubleshoot.

Thank you all in advance.
