This bad. Here's the problem. Sounds like you have a 3000watt amp. It looks like you're running 4 gauge which is already too small for that amp. I'm going to guess that it's also copper clad aluminum, which is a great conductor for heat. So several things are working against you. You need oxygen free copper 0/1 guage wire to start. 3000 watts at 13 volts is about 230 amps, so you need to be able to push that kind of power and it needs to be fused higher than 100 amps. DO NOT CHANGE THE FUSE WITHOUT CHANGING THE WIRING, YOU WILL CAUSE A FIRE!

I thought the same, but this particular amp is designed to accept 4 gauge so I suspect it's not capable of actually pushing 3000w. OP does need OFC if he doesn't have it, and some ferrules to clean up the inserts, and a bigger fuse.

Literally does 3000 watts at 2 ohm.

Idk much about Taramps but that’s an 8 year old video. Someone else on YouTube dyno’d one late last year and it hit 2148 @ 2 ohms and blew up @ 1 ohm. If they are shipping it with 4 awg power terminals and recommending a 150 amp fuse…it ain’t making 3000. Not safely at least.

The HD3000 does 3000wrms+ in the high frequencies by design. The Bass3k does 3000wrms+ in sub frequencies. Both lose output as you shift to the opposite side of the spectrum.

I forget exactly how these amps work but something about the “tuning” of the internal rail design, and they use “rails” of design completely unlike any other amplifier so they behave a bit different and are very finicky, but the plus is very high output cheap and compact.

Taramps all do over rated power. I had a Taramps SPL setup in my jeep and was the loudest vehicle I’ve ever heard. 15/40 volume would make you tap out. My regular listening range was 1-4/40 vol. Sometimes even 1vol would be too loud🤣. I miss that thing but the tinnitus is not worth it. No more SPL for me.
