Sorry Yimmy no advice for you as I am very pissy about my subwoofer I had installed by Tweeter up North. This is my seventh fucking speaker I have replaced in the spare tire hole in the trunk and I am sooooo fed up with it even though its under warranty. This has gone on for over a year now. JBL, Kicker, doesn't matter....whatever.....piss...moan...bitch...sulk. ..frown...guess it doesn't like my trance....fuggit...blah....the batteries are now going on the keyboard....AA or AAA? Grrrrrrrrr........
