hello everyone well i have a question about my woofers im stumped dont know what it could be. i have 2 10" memphis m3 subwoofers with a 1000 watt alpine amp to them they are wired at 2 ohms. well i just recieved my new pair because i blew my first ones and i think these are going also. i noticed that all of a sudden they get louder then they decrease its weird and i think my door speakers are also doing the same which are powered by a 4 channel alpine amp? i have no clue what it could be? it happend to me on my trip back to college yest. like a 3 hour drive. i have a alpine iva-d310 headunit. i HATE it i waited 6 months for memphis to replace these for them to blow in less than a week . any input is greatly appreciated thanks.

 

I need you to reexplain your issue, in a descriptive, consise and non jumping around manner.

 

sorry jeje. ok this is my setup alpine mrd-m1005 bass amp and alpine mrv-f345 for my mids and highs alpine iva-d310 as a headunit. what happens is that some times when im listening to it at a moderate level it seems to decrease in sound then all of a sudden it will increase to its original dont know what could be wrong i have everything grounded to one common ground except the head unit its grounded to the black wire that comes out of the harness hope that helps let me knwo if u need mroe info and i greatly appreciate it.
