I want to purchase this deck http://www.crutchfield.com/p_105KDPD...-KD-PDR40.html

and then this amp to power my new speakers http://www.crutchfield.com/p_500MRPF...-MRP-F250.html

the problem i have is the deck or reciever only has 2 preamp outputs and it says it would require 2 rca patch cables to hook that amp up but i also have to hook up an amp that is pushing my subs. Is there anyway i can hook the 4 channel amp up for my speakers and the amp for my subs? Thanks in advance
