Electrical wierdness ? !?!
 

hey people i have a 2000 gmc sierra i have two amps in it a us amps M2D2 i believe its called 3 10" image dynamic idq v3's, its wired down to do 2ohms bridged, the other is just a cheap sony 4 channel, ive got a kenetics hc800 cap, all 4 gauge wiring etc. stock alt (130amp) and stock batt

NOW THE PROBLEM: when ever i seem to blast my system like crank the volume to about 20-22 not always but sometimes it will sent the amp into protection mode.(us amps sub amp) the amp does not blow the fuses, it is not warm or anything. all grounds are litterally new, cap wiring in perfect, deck has its own ground, brand new RCA's ultralink gold plated triple etc lol, cap and amp r grounded separeate. it has done this before with diff amps aswell so i kno its not the amp. i was wondering if anyone new the prob cud it be the stock alt tht it try and pulls to much amps or ? how can i fix this any suggestions etc wud be so helpful thanks.

I cant help but wonder how ur getting a 2 ohm final load with 3 subs? :)

i do believe they r i cud be wrong there are all DVC 4ohm subs and ive got them wired like this . i do believe dont make fun of drawing i aint a artist lol

that's a 2.67ohm load no problems there... Probably a bad ground.

which grounds should i be checkin ? like i moved all my grounds, regrinded them. i was thinkin it was something to do with tryin to draw to much amperage kidna thing. or the fact im only running 4gauge if upgradin wire size wud make a difference?

use a DMM and check the voltage with bass hits

alright well i have two volt gauges in truck one nice aftermarket thts abit more accurate then stock but i do notice voltage wen im really hammering even wen im drivin will drop to just over 12.5V and then up back to over 14 then back down kinda thing, thts why i thought it might be time to get a custom 200 amp altantor and tht might fix it?

Check the voltage across the amplfier power terminals
