well I went yet another direction and now selling my Alpine amps. I have 1 MRP-M450 and 2 MRP-F250s. I am still using one of the f250s running my comps active. I have the mono out and ready to be shipped. 80.00 shipped each. They are good amps. No issues at all. Look like new. Here is a pic of the M450. Its rated 220w @4 ohms and 400@2 ohms. I was using this to run 2 Nak subs and it hits hard.
