Make sure your safety mode is off. Go to mode 9 and ENT and make sure it is off. If it still dont work you proabably have bad RCA wre or speaker wire. Hope this helps!

E-3 comes up


Hello svjonny13,

Excessive current draw can be caused by a short in the wiring, especially the output. Also, an amp may draw excessive current when operated into a lower impedance load than it can handle.

Too low of a supply voltage may result in the amp drawing excessive current, especially when operated at or near it's rated output. Voltage multiplied by the current equals watts. So if the amp is trying to produce X number of watts, the lower the voltage, the more current it needs. A power wire that is too small or too long may have too high of a voltage drop. A high resistance in the ground connection can also result in a significant voltage drop. Again, too small, too long, loosely fastened, or perhaps corroded. I'd check all wiring

Internal component failure can also cause excessive current draw. In that case, the amp needs service.

Hope this helps.

How to get amp status to come up on the screen of alpine d 310


you have to have an alpine kce-510m amp link module. You must also have a compatible amp, such as mrd-m300, mrd-m500, or the mrd-m1000. The amp link module plugs into the (ext) plug on the iva-d310 and the other end of the cable into an alpine kce-060m y-cable. The shorter of the y-cable plugs into the amp with the lowest id #.
