I'm not gonna lie, that was not helpful in the slightest lol thanks though.

The amp IS hooked up correctly, and it's not like I don't know what I'm doing. If it was overheating it would shut off after a certain amount of time, not delay the turn on process. It's also quite cold in the trunk, being that it's winter here in Minnesota. The amp is in an open area, albeit mounted sideways, and is hooked up with 4awg for both power and ground to the respective distribution blocks, which are trunked with 0awg. The amp for my sub works just fine, which is hooked up in the same fashion.

Like I said, it's a strange issue.
