I would only get 2. or more power. 1500 would move them but not to their full potential.

Type-Rs are rated for 500w each, and they dont really like being overpowered. Id say 1500 would be great for 3 subs, if that amp is actually putting out rated wattage. Being a MA amp i believe they are rated at 16volts or something like that. Which would actually put you in the 1000watt range on a 12-14 volt....
Just my .02

my amp is rated at 2000@2 ohms. I had a single type r 12 wired to 2 ohms in my car and beat on it pretty good every day. I never had an overpowering problem with it.

i would say go with 80inches he knows what he is talking about buddy of mine had a box designed by him and it turned out pretty good even though he didn't enough power.
but if this is going in a trunk i and i know a little about trunks i would say do about 1.5 cubes per sub cause i think that is what the subs call for and go with the port area 80 gave you. now if you are in a suv or ext cab then you do the 6 or 7 cubes and go from there but me i don't like doing those huge *** boxes takes up too much space and if you have a trunk you to make life changing changes to get it in.

Just because your amp can put out 2kw doesn't mean that you did. You'd reach thermal/mechanical limits far before you put a real 2kw to a type r.

no, im just saying i was running alot over rated power and nothing happened. Lots of people way overpower them with no problem. you cant really say they dont like to be overpowered.

I gave my R's 600 watts each (probably more considering it was a kicker amp and they're underrated) and they wanged :)

I know it's not a ton over the rated value but it just shows they CAN be overpowered and handle it fine

Yes, they can be. I ran mine at 750 rms each, but he was talking about 1500 to it. I dont think these speakers could take 1500 true RMS wattage, but thats just me...
