No, Not yet.
I really haven't had time due to the holidays and juggling work.
I'm gonna conquer it Saturday morning.
I'll let you know.
Thanks for all your help.

I replaced the RCA's coming from my EQ to my Amp for the Sub, Since that fix I haven't had it happen again.

I do have another question though, That’s Amp related;
Can a single channel on an Amp go in and out whenever it wants?
My highs on just my drivers side keep fading out, It seems to be when I'm on a long trip, Like more then 20 minutes of driving.
It may be coincidence but that’s when it seems to happen.
All my door highs are connected to a RF amp, The passenger side never fades but the left side seems to always be the culprit...
Any Ideas?
hey man i think that it might be the amp. what year is your car and how old is the alternator? i think that the amp is sucking all the power out of the alternator and i think that is why there is the "in and out" instance. i think that or a loose wire somewhere, perhaps in the amp itself. if you checked all of the wiring, try to test it with another amp. u may need to get a capacitor. if u check the amp and all the wiring and everything checks out it is probable the alternator/power supply. gell cell is in your future perhaps, or even a capacitor? i have a capacitor brand new in box if that is the case. let me kno i helped at all.

I'm not sure but I think I may have just found my problem. I do have a 1.0 Fared Stinger capacitor, But as we speak I'm tearing my components out and found some brown syrupie stuff on the bottom of the Cap, Could it be leaking something? Could that be my problem all this time?
Also I've noticed that when I let off the gas my volts meter on the cap reads 14.1ish, But when I give the car gas (both day and night) the volts drop to 12.2 and lower in some instances.
If I'm not getting enough juice to the amps...could that be the reason the sub pops and the highs fade out at times?

Man...I wish someone with more knowledge about stereos could physicaly help me out.
I'm in Spring Hill, The only people that know anything around here is AVS, And they are so damn expensive.
The Holidays killed my wallet and I'm slowly getting back on my feet financially,, I don't need these headaches right now.....Damnit!

Anyway, Thanks for everyones help, I think I'm about to just tear everything out and say screw it!

The amp is in great condition.
It's a Power Acoustic Hammer series 800 watt, I'm only trying to power a 12" Cerwin Vega with it. It's not even a stroker.
SO if it was my Sub amp...why would I be having problems with my Rockford punch 100 at the same time, I only have one component set running off of it.

Also, with my capacitor, It used to turn it self off after a minute or so, Now it's constantly reading out the Volts...even when nothing at all is on in my car.

try everythign without the cap..
cap could be providing power irregularites..

the thing about both amps.. if one amp is shitting the bed and drawing crazy current.. the other may not get full pwer..

yeah it sounds like the system is protecting itself from blowing up due to irratic current.
