The maximum continuous current/ampere output can be calculated using the formula P=IE, power is equal to current(or amperes) multiplied by voltage. The Club 704 boasts 100 w(rms or continuous) x 4 at 2 ohm, making a total of 400 watt output. I am not concerned with peak or max output because those are for short dynamic bursts. Music is not static, it is dynamic. Which is to say that the signal strength for audio is constantly changing, Just because the radio screen may say 25 or 30, the output power is changing due to the data being reproduced is not at a single constant level. Because the output is continuously changing, the amount of current the amp requires is continuously changing. By figuring out the max continuous current used, you can figure out the lowest fuse rating required. Vehicle voltage varies, 12 v with the engine off, to 14.4 v with engine on and no accessories operating. 400w/12v = 33.3 A. 400w/14.4v = 27.8 A. If you push the amp to its limit of 400 w, you are looking up to a 33 amp draw on the vehicle's electrical system. 280w/12v = 23.3 A. 280w/14.4v = 19.4 A. If you run 4 ohm load on the individual channels of the amp, you are looking up to a 23 amp draw on the vehicle's electrical system.
Sorry, there was a problem. Please try again later.The fuse rating is 30A x 2.
