Blown Sub?

[NINYO]

Hey guys i hope u can help me out!

I gotta alphasonik PMA1200DA amp and a alphasonik PSW912 SUB connected 2 a alphasonik 5fared cap running at 1ohm am using a audio control matrix as a line driver and also a epicentre.

When i first installed the system i was told 2 keep the gain to low and if i wanted more bass i should use the epicentre. i was still not happy coz the epicentre provides more of a rumble then a punch so i kept the turning the gain up and kept it 2 about a lil more then half way.

Untill recently, everything was working fine but then my sub just used 2 cut out now and then. then start working again like when i closed the trunk or went over a bump.

so i thought it would probably be a loose connection and re wired and mounted everything again.

i didnt drive this car alot coz i was still registering it but am sure the sub sounded a lil more distored then usual - i put this down 2 tuning coz i adjusted the low pass filter, phase and the sub sonik too.

The problem disapeared for a while but while i was driving on the highway the sub cut out! i was expecting it to start again if i go on a lil bump or something - it did for a few seconds then died again.

when i got home i checked everything, it all seemed ok, there was no strange smells or loose connections. the amp switched on, and am sure there is a signal coz the light on the driver is flashing to indicate diffrent volts and the light is flashing on the epicentre everytime the beat comes in. i opened up the amp but there was no visable burn marks. and the same with the sub - they both still look like brand new!

there isnt even that 'thump' there fron the sub when u first switch it on.

so what u guys think it could be? am praying its not the amp! //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

ground wire for your amp might be loose or the remote turn on wire for your head unit might be loose causing the music to stop then start again.

x2. I would re-check your ground wire or rca's.

could it be a problem with the ground even if the amp is powering on?

Yes, if it's making contact but not good contact a bad ground can give you all kinds of weird issues.

check the terminals where you connect the amp wire to the sub, sounds like the same thing my were doing, found out the wires were burnt and came apart.
