no1sirbutler Newbie 2001 KB'd GT Join Date: Jun 2008 Location: WVa Posts: 4	^^^ that sounds like a power issue. I would meter the power at the input of you distribution block and see what it is. Several amps draw a lot of amps and if you cant keep the power they need they will shut down. Also when they act up, are there any lights on the amp that light up? __________________ Don't make KENNY scream at you!!!!

moneygreenstang Regular 99 v6 Join Date: Jun 2008 Location: Southern Florida Posts: 54	well i sort of fixed the problem for now i wired two alpine type s 6x8 and 2 pioneer 6x8s to the power acoustik amp and left the subs how they were they worked fine and sounded great until the volume got to 20 or above when i turned the volume above 20 usually around 22 or 23 the subs would quit but the amp for the subs would stay on and the 6x8s would keep working fine if i turn it down the subs come back and dont miss a beat subs are brand new and work great without the second amp __________________ CAI True Duals 17" GT500 Chrome 4.10s SCT SF3
