What is the ohm rating for your Type R? If its a DVC 2 ohm try this amp http://ecx.images-amazon.com/images/I/41K1h--nogL._SL500_AA300_.jpg If its the DVC 4 ohm try the Hifonics BXi1210D or BXi1209D. Just do a google search and you can find those amps brand new for around the price of both the amps you have listed and would push that 15" Type R with the power it needs. I paid $248 for the BXi2010D which @ 1 ohm is 2000 watts rms. Their a little overrated but are great budget amps. Hope this helps...
