Magnum s980

The 2 mic jacks are supposed to allow the radio to be mounted in different ways while allowing max reach of the mic cord. Or if you mount it dead center of the cab you can add a second mic so you and a buddy can take turns talking on the radio w/o having to hand the mic over.

 

Oosp, didn't see "mic" in the OP.

 

X2 on what Turbo-T said!

 

How much power is the 980 putting out?

A straight 4 pill amp you will want a good driver for it, around 75-100 watts.

 

If your Midnight special 400 is this one, Your radio will drive it just fine. I would have the dead key set at 10 watts and let it swing. [TABLE="align: center"]

I would not drive a 1x4 or a 2x4 with that radio. way to much for any amp with a driver pill, and a 2x4 is something I would be looking to sell to the first guy with cash.
