[QUOTE="Slammed, post: 7773974, member: 554316"] Subwoofer RCA cable is not connected to the amplifier yet the subwoofers seem to be playing (sounds like alternator whine/static). Subwoofers sound the same when the RCA is plugged into the amplifier. I checked all the RCAs and they are fine. Front and Rear speakers play fine (with little alternator whine). This started happening once I installed my head unit. But the Kenwood was brand new and everything was hooked up properly. The amp was fine prior. Subs also played fine when using my Audiocontrol LC6. [B]Again, static/alternator whine plays through the subs when any of the rca cables are plugged in. Subwoofers play a bit loud (with whine) only when the 2 or 4 channel input is selected on the amp...not the 5 channel option.[/B] My amp: [URL="http://store.mtx.com/caraudio/archive/thunder405.cfm"]MTX Car Audio - Archive - Thunder405[/URL] My h/u: [URL="http://www.sonicelectronix.com/item_33490_Kenwood-eXcelon-KDC-X395.html"]Kenwood KDC-X395 (KDCX395) CD Receiver w/ LCD Display & SAT Ready[/URL] Please help [IMG]//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif[/IMG] [/QUOTE]
