BassHead1990 Posted March 8, 2022 Report Share Posted March 8, 2022 Has anyone came across this issue before? Amp will randomly shut off while driving and I'll pull over and check across the terminals and it reads ~2-3V; then it'll randomly come back on and reads 14.8V. Ground seems good, getting 14.8V across remote and ground. Nothing is loose under the hood ( only 0.2V drop from front to back). I got a couple more tests I'll run but just seeing if anyone has experience this before. Would Clipping perhaps be a cause?

Dafaseles Posted March 8, 2022 Report Share Posted March 8, 2022 When you say check across the terminals, I assume you mean just the positive power wire? 2011 Chevy Silverado under construction My build log here. Check it out! Link to comment Share on other sites More sharing options...
BassHead1990 Posted March 9, 2022 Author Report Share Posted March 9, 2022 Yes, the positive and negative inputs on the amplifier. I haven't yet been able to set a proper gain on the HLC-2, I'm wondering if a clipped signal is a factor. Next time it happens I want to remove the power wire and check power to ground to see if it's a "high Resistance" to drop it down that far.

Dafaseles Posted March 9, 2022 Report Share Posted March 9, 2022 It could be a bad ground or grounding location. But, I know you said you checked everything, but to me it sounds like something is loose. On the battery terminal, or a fuse, or any place they'd a connection. I'm not saying 100% it's that, that's just what it sounds like. What amplifier is it? 2011 Chevy Silverado under construction My build log here. Check it out!

SnowDrifter Posted March 9, 2022 Report Share Posted March 9, 2022 Yeah this reeks of a funny connection somewhere Go through everything. Disassemble, inspect, test, clean, reassemble. Alternator stud, ring terminal, battery clamp, battery terminal, wire into fuse block, fuse, wire out of fuse block, amp terminals, ground terminal, ground location, etc etc etc. Give every crimp / solder, termination a HARD pull too. If you're worried about it coming loose, re-do it. If it comes loose, re-do it. Skip nothing, assume nothing is good. Actually go out and do it. If it were all good, this wouldn't be presenting as an issue. Gotta find it. Also check your fuse. Half blown fuses do funny things. Easy check here is a DMM across the fuse while the issue occurs. ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
Kyblack76 Posted March 10, 2022 Report Share Posted March 10, 2022 Id look heavy at the ground. SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
BassHead1990 Posted March 11, 2022 Author Report Share Posted March 11, 2022 Okay, I'll do a breakdown this weekend of EVERYTHING. I keep hinting at the ground too but it's like it it'll be playing @ 15 volts no problem then on a certain songs the voltage will just drop to 3 volts and shut down (no protect mode) then after a while boom it's back and playing 15 volts again, amps not even warm. I agree, there's something that's off or I wouldn't be dealing with this. I'll keep you guys posted!

BassHead1990 Posted March 11, 2022 Author Report Share Posted March 11, 2022 I wish, no the amp shuts off usually at high volume, If I'm playing at a normal volume, everything is good.

Oh, i miss understood. Its good its shutting down. Every time ive seen voltage drop to insane amounts, it was always a ground issue. Comes and goes type of shit, always a ground. Id give that a real real REAL good look over. Good luck. SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
