Just bought a KENWOOD Class D amp 1800 watt max and 500 rms at 4ohms and 2 12 svc 4ohm Memphis 15PR12s4 and i was wondering what is the best way to hook them up to the amp for the best sound, and bass quality?

DIAGRAMS WILL BE ALOT OF HELP ALSO

Is the amp stable at 2 Ohms? If so, just wire them in parallel.

The amp is 1 ohm stable

I did a quick search for the amp, if it's the one I found, it should have connections for 2 speakers, just hook them up to those connections, you don't have to do anything fancy. That will put them in parallel and give you a 2 ohm load on your amp. I did a search and it looks like your subs can only handle 250 watts rms each, if that's correct, you'll have to keep your gains down because it'll be giving each sub 450 watts rms.

Ya thats true the subs only handle 250 watt rms but those subs can handle alot more the retailer i bought them from has 2 12 in his car and a 2000 watt that puts more rms in to them then mine does and hes had them in for a yr now with gain on amp set all the way up and the gain on head unit down in negative i have gain up on my amp almost up all way about 75% and head unit down at -6 so idk if they blow i got warranty even tho i dont think they will cuz had them wired parrell and had the bass gain in head unit at -6 and had it up to and over 20 and sounded good had it runnin for wwhile just the amp will shut off if hav gain in positives and run it for 30 min or so

n thanks for the help

Well, the gain definitely shouldn't be all of the way up, 75 sounds pretty high as well. The bass boost isn't what you should be basing your gain off of. It really depends on how many volts your preamp outputs are - the higher the voltage, the lower you set your gains. Then from there do some tweaking to the bass boost and turn your gain down a little if you have to to compensate for it. Might not be a bad idea to have a stereo shop set up your gains \with an oscilloscope though.
