Yes, it can easily up to 8 speakers with this 2 ohm stable amp. Each would receive 62.5 watts rms, and 125 watts peak.

I have an all in one sub (integrated amp), and am running 4 speakers, is there an output for this, or do I need to run my sub off the head unit?

I did not see a feed through rca on this amp. So would need another from the head unit.

What size fuse should I use on my main power wire?

It depends on your wire size, for example, 4 gauge is safe to run 100 amps but someone runs a 250 on their zero gauge.

Will this run a 12 inch sub?

Yes, read the instructions, and bridge the amplifier to 2 ohms mode. Amp is good for 190 watts RMS each per channel (for 2 channels) or 380 watts for one 2 ohms dual voice coil sub.

Will this amp be good for 2 6X9, and 2 6.5 speakers?

Yes, but you will have to adjust the power. This amp packs a little more power than you would expect especially for a 6X9 and a 6.5, but you should be okay.

What is the rms power rating at 4 ohms x 4 channels?

I am not sure because I have yet to install it. 4 ohms x 4 channels = ? rms...

Pioneer GM-A6704 4-Channel Bridgeable Amplifier with Bass Boost

The Pioneer GM-D9704 Amplifier is a 4-channel amplifier that is 2 ohm stable according to the manufacturer, which means that it can easily up to 8 speakers with this amp. Each speaker would receive 62.5 watts rms and 125 watts peak, making it a good option for those wanting a powerful amplifier to drive their car's speaker system. However, some customers have reported issues with the amp, such as it not working straight out of the box, not being as described, or only lasting a short period. Others have had a positive experience, finding that it works well, has plenty of power, and is noise-free. One customer did experience a loud pop when the system turns off and found that it was the amp causing the issue, not the installation, so beware of this potential problem. The lack of an internal fan also raises concerns about how hot the unit can get during operation.

Pros

2 ohm stability makes it easy to drive up to 8 speakers
Enough power to drive door speakers and larger subs
Positive reviews from some customers

Cons

Reports of the unit not working out of the box
Some units not lasting long
Concerns about heat with no internal fan
