I've had an ongoing problem where my amp will randomly start blinking the protect light consistently until I turn the car off then on. This causes the sub to turn on for one second and off for one second in a continuous loop. The speakers still produce continuous uninterrupted sound though. I have no idea what's wrong I've tried 3 different subs and they all produce the same outcome, it could be the amp, but sometimes I listen to music for an hour straight without it acting up. See video attached for clarification.
I have a Memphis Audio PRX1000.1 powering two Sundown EV3 10'S. Subs are wired to a 1 ohm load. So the issue I keep have reaccuring is the amp will suddenly quit providing output to the subs, when this happens I can reach back and literally just touch the amp with my hand or even just a finger tip and output comes back and subs start playing. The blue status light never changes to red or cuts off or anything just stays blue as if everything is fine. Amp isn't hot to the touch, no popping or chirping or anything issues with the sound when it is playing. There is no pattern as to when the issue occurs. I could be sitting still in my drive way this it just cuts off, driving down the road, music up loud, or music playing on low. Then just reach back and touch it and they kick back on. I've also noticed this issue while adjusting knobs on the amp, like I'll tweek the LPF and it'll stop, touch the knob again with the tip of the screwdriver or something and it'll kick back on. It's extremely annoying and this is my second amp being that I exchanged the one right before it (same make and model amp) because it had issues. I know it's got good ground I recently just added a new dedicated grounding post just for it.
So my question is, has anyone had similar issues I'm having before with this or any other type of amp? If so did they ever figure out and/or solve the issue?

I keep thinking this and can’t figure this out in my head and it’s driving me crazy. So let’s say I have a 2 channel amp and two 2 ohm subwoofers. My amp is stable bridged at 4 ohm so I wire them in series. Now both subs pound at the same time. Now let’s say I just hook up each sub to each channel and let the subs run in stereo?! What would happen? Will they pound the same or pound in stereo and be kinda off?! My real thoughts on this are really because I have a really good zapco amp that is 1 ohm stereo stable that I could potentially hook up a lot more subwoofers too but only in stereo not bridged. But I just want to know will the subs pound the same in stereo mode as apposed to bridge mode or even mono amp style? Also if I did hook them up on each channel, is there A way to just make them run in mono mode instead of stereo? Thanks guys. Also I’ve had an account here but I’ve forgotten it and used my facebook for a new one lol.

Hi, thanks in advance for any help. I've added a leisure battery to my van, using the wiring in this video: https://youtu.be/oOQHe_cZtI4?t=1044
I have this amp: https://www.caraudiocentre.co.uk/product_m-pioneer-gm-d8704_p-41014.htm and this head unit: https://www.pioneer-car.eu/uk/products/deh-s3000bt
I'm assuming the head unit will be fine if I wire it in to the fuse block (this one: https://www.amazon.co.uk/gp/product/B01IVRC9RA/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1).
Should I re-wire the permanent or ignition switched terminal from the back of the head unit to the fuse block.
And my main question...
For the amp, Should I be connecting that via 16mm cable straight to the battery (or to the isolator switch in this case) and does it need its own fuse.
So I bought used audi a3 1996 and it has a subwoofer that looks like it was installed by audi. The speaker is 6.5 inches and 2x3 ohms. So I don't really know what could do as a replacement speaker. Also there are 4 pins on the speaker so I don't really know how that works.
These are the pictures of the old sub:
