So I’ve recently switched amps and it was playing fine, installed it on my back seats. I noticed that it turned off, laid my back seat down and noticed the screws I Installed the with amp had came out, saw it was in protection mode. I’m running it at 1 ohm. It’s still loose right now. This morning it probably played for 10 mins then shut off but when I was leaving from work it played for about 30 mins on my way home. It’s not getting hot, I just wondered if it’s going into protection because the amp is moving around and the wires are being pulled. Because I got home and it was in protection, turned the car off then back on an it was working fine.

you should start with getting it properly secured. what amp is it and is it actually 1ohm stable. In theory it should work fine even if not fully secure, but it depends on how much moving around it might be doing.

If you want, you could just play it sitting in your drive/garage for a while and see if it acts up. Are you sure it's a 1 ohm load? you don't have any stray wires shorting out or anything, do you?

An amp that is flopping around gives me reason to believe that maybe this gear wasn’t installed well in general. Make sure the amp is secure and that all wires are properly secure on both ends.

Ground could be shorting out when the amp is moving, sending it into protection mode...

It’s a pioneer GM-D8701. See I just figured since it was on the box and it didn’t really get hot, I figured it was all good to run at 1. I mean I had drilled it in the same way my last amp was and it never moved. I’ll definitely give everything a look over, it definitely needs some extra love, I installed it super quick so yeah it’s definitely not in there the best it could be

Do you know that it is one ohm stable? I doubt it is...

Honestly not to sure, I can’t find anything online about it.

Is this your amp? It took all of 2 seconds to find it directly on the pioneer site, very first result using google
Looks like you should be safe. So you need to check everything else. Like I said originally, I would also see if it does it without the vehicle moving

No, mine is the gmdx 9701, mine has (3) 40 amp fuses.

but isn't it similar? I guess I didn't pay close enough attention. just thought it was odd that both of you are having similar issues on pioneer amps.
Also; I posted 3 links for videos for you about the skar and JP amps

Yes, it's similar, I think the pioneer amplifiers are not good for 1 ohm.

very possible but would be mismarketed and not good of Pioneer to do. I wouldn't think Pioneer would do that but who knows. they are more of a budget minded amps, so anything is possible

Yelp, I agree. Wish it was like it was when I was a teenager, Precision Power art series amplifiers, they don't make stuff like they used to.

UPDATE: Unplugged all the wires re-twisted them and hooked it back up an it played consistently until it shut off and I saw the amp was in protection mode, I smelt something burning I thought something was on fire. So I got out and checked everything and nothing was wrong. Got back in my car this morning and it played fine. I think I’m pushing to much power to my kickers and burning the coils out but I’m not sure. Cause just like last time, the amp was barely even warm
