Question about Earthquake Sound PH-D2 Car Audio Amplifier
When I connect input cable from the headunit the red light in the amplifier is on of the 6 input channel 1000watts earthquake amplifier,
but without connecting, green light is on I check all wiring cables they are all fine.
Cables are either shorted, or deck is putting out too much power for input on amp... many new head-units will put out up to 7v on the output jacks (RCA) the amp may only want to see up to 1v will need to consult head-unit manual for adjustment of outputs.
