Is the fuse the problem?
Now, before you tell me, yes the correct fuses are in the mail. But I'm wondering if the smaller fuse is the culprit here.

I removed an Alpine MRP-M500 amp from my truck, which took a 60Amp fuse. I replaced the amp with an Alpine PDX-M6 amp which needs an 80Amp fuse. My issue currently is this, I'm not getting the same level of performance from the PDX that I got with the MRP. My gains are higher, in fact, maxed out, and the sub level control on my HU is maxed as well, usually, it's set to a 6 or 7.

So, is the smaller fuse the issue here? Will I get better performance once I get the larger and correct fuse in the mix?

No... and unless the existing wiring is suitable to carry 80a, installing the 80a fuse will increase the risk of fire.

It is 4ga. Solid ground point, all run and tied properly so that it looks factory. I'm not worried about the wire, more the performance because of the fuse.

The fuse is not the problem.
The fuse is simply a safety device that opens when overloaded. It is not a resistor or a regulator.
If the fuse is not blowing on the new amp, then it is "adequate" for the job for now.

I figured out the issue. I had selected the wrong voltage input on the amp. Selecting the right one, I have the gains at 2/3 and have some of the best bass I've ever had in this truck.
