Help me find the solution...
to my little audio glitch.
First off, system description;
Car - 2002 ford focus zts sedan
Head unit - Factory in dash 6disk changer
Front speakers - Polk EX3550 5-1/4" component set, tweets at base of A pillars
Rear speakers - Polk EX3550 5-1/4" component set, tweets halfway up C pillars
Sub - Pioneer VCCS Pro 12" 4ohm sub in sealed box
High end amp - MTX6304 running polks at 4ohms, HP xovr at 180hz
Sub amp - MTX8302 bridged 4ohm LP xover at 70hz
Battery - optima red top
wiring - big ass as fat as it gets monster wire to dist blocks and monster wire rca's. all high quality qold connections
configuration - line leval converters off "front" channel of factory player, amps daisy channed with rca patch cables.
Okay, on to my problem;
99% of the time, this system sounds GREAT with excellent imaging, fantastic definition and increadable punch at super high volume. however, when its up fairly loud (not super duper loud) i sometimes get a 'crakling' through my tweets during high bandwidth passages (high volume across the entire pitch spectrum). example, the song 'awake' by godsmack just makes my system crackle up like rice crispies.
okay, i know the factory stereo and line level converters could be definite culprit, but i'd be really sad if i had to go with a CHEEZY looking aftermarket single disk unit instead of the clean looking, intuative and convenient in dash 6disk changer.
i was cranking it up while sitting in it at night and noticed some definite flickers in the dash lights during loud passages. maybe when both of those big ass amps are cranking they are running out of juice and its time to add a capacitor to the system?
okay, whats the verdict? of maybe something i havn't thought of yet? i've noticed NO other audio anomolies, other than this objection its my dream stereo.
