It will work, but it might leave you a little underwhelmed. You can find a quality amp in the 600 rms range for maybe a 100$ difference, I’d just do that now rather than potentially buying another amp a few months down the road.
Is the amp they are trying to sell you much cheaper than that?
SEE EDIT
Original comment: That amp only puts out 1000watts "MAX" which means the RMS value could be anywhere from 400-500watts. The GM-D8601 Actually puts out more real watts. I suggest neither of those amps... and go with a Rockford because it does have a subsonic filter.
It's more money, but it is much higher quality.
EDIT: I'm incorrect disregard the above.
You would be paying quite a bit for an amp that puts out 800W rms @ 4ohms. It would be much cheaper to find one that puts that much out at 1 ohm. The difference between running 800W rms at 1 or 4 ohms has little to do with SQ and more to do with the efficiency at which the amp operates (4 ohms being more efficient).
For simplicity's sake, just get 1 amp that puts out 800W rms @ 1ohm. Having two amps would be better for heat dissipation, but you're not in any SPL competitions so that isn't a huge factor. I am sure others have better budget amps, but since you already have Rockford subs you should go with this amp:
RF r750-1d I have one and it puts out 900W rms on the birth sheet @14.4V. I set the gains to about 800W rms for my T1, and even after running it hard for 1.5 hrs it barely gets warm in the center.
Yeah I thought that amp seemed a little low for this sub. It's rated at 750 RMS. Would this sub sound better wired down to 2ohm than 1 ohm because I was looking at this amp Rockford Fosgate Prime 750 Watt Class D 1 channel Amplifier https://www.amazon.com/dp/B004T166L8/ref=cm_sw_r_awd_BBd5ub11KXKKZ
Morel Maximo component set - $150 shipped
Kenwood ddx374BT - $220 shipped. Comes with $40 off the dash kit you might need
Fi Alpha 12 v2 - $180 with the "Dual 2 Xmax" option (absolutely necessary), plus shipping.
Rockford 750.1d - $223 shipped. These are underrated little tanks.
Knukonceptz OFC 4awg kit - $60 shipped.
Other supplies (wood, glue, wire harness) - $70
Total - $903. This would be ideal. However, if you need to skimp on something, you can get these options instead: Hertz dsk component set - $115
RF p2d2 12" sub - $104
Alpine single din HU with BT - $161
PPI monoblock amp - $132
New total - $642 plus up to $70 for the dash kit, so $712. If you get the PPI amp and RF sub, run it at 4 ohms.

This one would give the best sound for both?

Also, a 4 AWG wiring kit from Knu Koncepts
Get the 4 ohm version of the sub so you can wire it to an amp at 1ohm - Either way just set your gain properly so it is feeding your subwoofer 750 rms.
Did you have this in mind? Even with wiring my subs down to 1ohm would that not still underpower the subs? or is 50WRMS not too big of a deal? Appreciate the input.
Thanks, I was a little worried about the amp too. I found a Rockford Prime 750.1 D on Amazon for $192. I'll probably be picking this up today.
