[QUOTE="JChap, post: 7725542, member: 641409"] i had my system installed by a professional. I have an Alpine INA-W910 in dash head unit with nav. all brand new equipment JL door speakers and 10" JL subwoofers. 400 watt 4 ch for the speakers and a 600 watt for the subs. system worked great for 6 months. then the level of bass started dropping randomly. the status lights on my amp did not change indicating any major problem with it. i took it in to the audio store and got another amp put in due to a high pitch whine coming from the amplifier itself. they said it indicated an internal power issue with the amp. my system was back working great for a couple months and now it is happening again. there is no high pitch whine this time. all connections are good and i have a steady 14 v of incoming power. the volume out of the speakers remains the same. just the subs dim out sometimes for an hour or more. they never cut out completely tho. any insight would be appreciated [/QUOTE]
