I have an Alpine MRP-MP500 am. I have had it since 08, and it was pushing an 07 Kicker CompR 15" up until a few months ago. I just replace that sub with a Kicker CompS 2-ohm 15". All week I have had the amp turned down to break in the sub. I turned the amp up to where it was before, and today the amp started smoking. Please help! Is my amp done? It still runs the sub, but like I said it either starts to smoke or smell like its burning????.......
