hey guys, i DIY'd a full sound system (HU,subs,amp,speakers) and everything worked fine, BUT, i recently changed the HU to a crappier one and now when i change from tuner to cdplayer (vice versa) it makes a loud *pop pop! from the subs irrespective of the volume setting..
i think maybe the RCAs make be in the wrong slots, but i want to be sure thats the problem (its a bloody hassle to get to the HU) or could it be the HU itself?!?
