Hey people. I have a very simple question that i need answered. I have one hcca 15.2 and i have one hcca 25001 amp. I plan on buying another one of each to put in my car but just out of curiosity, both the 15.2 and the 25001 amp have been sitting up unused for quite some time, and i would like to know would that cause any malfunctioning in either of the two? Just curious, Thanks!
