I purchased a sound system for my boat and was going to install a marine amp. for the speeker system. With a 1000 - 1500 watt amp it is reccomended to use 4 guage power feeds from the battery to the amp. I will also have inline fuse at the battery. My question is the possable interfearance with VHF or other elctronics, GPS, depth sounder. Is there a concern for this.
