music chopping in/out at higher volumes

no the lights on the deck do not dim or flicker at all.. no matter the voume... and also.. not to get onto another subject but.. would you happen to know why my music sounds so much cleaner when i fold my back seat down-(making the trunk and the cab one big airspace)... when i have my seat up-(separating the trunk from the cab), the music particularly from my rear 6X9's sounds scratchy so to speak... somewhat distorted..

and that is exactly what i thought it was... so what i did was i went and bought a pair of what i want to call "speaker buckets" or the things that would ideally make an in-door sealed enclosure for the speakers.. i'm sure you guys have a name for them but they're like a 6X9 fitted bucket that you sit the speaker in and then screw that into your door or in the rear deck above the trunk. well they wouldn't fit just right so i had to cut them and it basically defeated the whole purpose of the enclosure..

do you have a solution in mind? i'm actually about to create a topic about this so that it can get more visability and hopefully more solutions ideas.

thanks, seth

This has already been eliminated. i am an idiot recently asked if the display lights on the deck dim when the problem occurs. The reason why he/she asked that is because he/she thought it may be a loose (or inadequate-sized) power and/or ground wire.
