Looking at getting the Kicker ZX700.5 or ZXM700.5 to power a sub and cabin speakers... The "M" is Kickers marine rated version...

Question: should I get the marine rated version? Does it matter since it will be in a "dry" location?... I never run in salt water. Obviously, if I can get either amp for the same price, I would go with the marine rated amp... But it is looking like the non-marine rated amp is going to have a cheaper pricepoint online... FYI My other amp powering the towers is a wetsounds syn2, marine rated...

Thoughts, experiences? Anyone? Phil?
