wa howie damn cb

anyways, if you experience the issue only AFTER you change the HU, then consider swapping similar HU (that supports RCA for example) and if it the issue doesnt occur, then consider replacing HU (eg: non alpine/pioneer or other reputable brands such as eclipse/clarion/blaupunkt etc can be considered crap and you're probably better never purchased it in the first place) as it may be faulty
