The amp barely needs any power to be on! only a 7.5 amp fuse in it! This amp is great for very small speakers, tweeters? I hooked them up to my kicker 6×8’s and they power them but not enough cause the speaker is 60rms. I hooked them up to 2 powerhorns i bought off amazon and it is loud!!! the powerhorns are hooked up to a switch so i turn them on when i need to and off to stay outa tickets;) but for around 60 bucks you can have this and 2 powerhorns and i promise!!! i mean promise when your driving around some people will start dancing it is that loud! People hear me coming from about 100 yards away! crystal clear music from a distance!!!
