Hey guys first time posting here so go easy [img]smile.gif[/img] . well I recently installed my new system and now im getting some funked up problems. First i'll list what I have.

Alpine cda-9807 HU
Alpine 500watt mono amp
Alpine 200watt 4-chan amp
Alpine 6.5 coax (rear)
Alpine 6.5 component (front)
2 Clarion Power subs
and a 1000watt cap for the mono

Everything i have hooked up have 12 gauge power wiring and i have a 4 gauge power wire leading to the back to a dib bloack for the amps.

Now just in the past month my speakers seem to but out every once in a while when i turn the volume up past around 14-18. The subs still pound but the speakers cut out and quite frequently too. I have tried a ton of things including grounds and magnetic issues and cant quite figure out what the problem is besides the deck because its a power handling issue.

sounds to me like one or more of you speaker wires maybe shorting to ground.

Agreed, check your door speaker mounting, the speakers may have "shifted" themselves over time, and with vibration, g-force(tight turns), the speaker terminals may be too close too the door chassis.
If those connections are safe, look for a pinched speaker wire.

okay ill try that today and get back to u guys. Thanks for the tips

Well thanks for the ground tip, I belive it was one of my rear speakers touching my trunk spring and grounding there. Once again thanks guys.
