I have an Alpine MRP-F300 four channel, specs say it can do 50w at 4 ohms and 75w at 2 ohms.

I'm running my active two way setup with this amp. My tweeters are 4 ohm and mid bass are 2 ohm (2.2 to be exact).

My question is: Since the amp is stable at two and four ohms, can I use two of the channels to power the 2 ohm woofers and the other two channels for the 4 ohm tweeters without harming the amp?

I'm not concerned with the differences in output level or anything like that, just whether or not I will harm the amp. In my mind it doesn't seem like it would be a problem but I figured it would be smart to check.

Thanks in advance.

Yea. It'll be fine as long as the amps 2 ohm stable. Many people run different impedances on a 4 channel amp.
I run an 8ohm midbass, 8 ohm midrange and a 4 ohm tweeter on a 4 channel amp.

Yep what he said..i have a 4 channel running 8 ohm midranges and 6 ohm tweets
