Subs cut out, amp stays on, doesn't go into protection mode, what

[CaptainMcFunk]

Hey guys, I've been battling this car audio gremlin for about 2 months now trying to track it down, and I'm exhausted. I want to see if someone smarter than me can help me out. here is my situation, and equipment list below:

 

• 2 - Rockford Fosgate P3SD2-12 subwoofers. They're 2 ohm DVC
• Subthump Dual downfire box with amp space: http://subthump.com/Chevrolet-GMC-Custom-Subwoofer-Boxes/Silverado-And-Sierra-Crew-Cab-Custom-Subwoofer-Enclosures-by-Subthump/2014-Up-GM-Crew-Cab-Dual-Downfire-Box-With-Amp-Space-Hot-Product.html
• Power Acoustik Edge EG1-2500D Amplifier -- 800w RMS @ 2ohms
• PAC Audio PDLC21 2-channel Digital line output converter

 

Here is my problem - After about 10-15 minutes of playing my stereo, my subwoofers just cut out, but the amp DOES NOT go into protection mode, or shut off. The light still shows it's on, and the light on the line output converter shows it's getting power/signal. I literally cannot figure out what's causing it. The amp is not hot all all (to the touch, I don't know if it could still be hot inside by any chance?)

 

Secondary question: The subthump box has terminal cups on each side of the box for each subwoofer. My issue is I'm trying to wires these subs to a 2ohm load, which would be this diagram here:

 

My problem is because I have to go through the terminal cups, Sub 2 goes to the terminal cup, then from the terminal cup to Sub 1's terminal cup, then from Sub 1's terminal cup to the amp. Does this still get me to 2 ohms in theory? If not, could this be the issue?

 

 

Let me know if there is any more info I can provide to hopefully help out? Thanks so much!

90 views and no responses. cool. But for anyone reading this later, I got it figured out, it was my amp that was cutting out, there's some sort of short in the level adjustment screw; moral of the story, stay away from cheap power acoustik!

I am having trouble with the PCM cutting the alternator off and running system at 12.0-12.2 volts... this is cutting my amps off, did you not have any issues with this?

@CaptainMcFunk what part of LR are you from. I grew up in Gravel Ridge, which is now Sherwood. Got family in Searcy, Cabot, Conway, LR, Bryant. I'm all over that place all the time.

I’m having a similar problem with a 2017 and cannot track it down either
