I have a alpine deck, (x100)
alpine amp (MRP-M1000) 1000watt rms @ 2ohms
alpine sub Type x(wired at 2ohms 1000watt rms)
All of a sudden when my music was playing low the sub stopped working and I don't have a idea why.. I bought a brand new sub to test if the amp is working and I'd get the same problem..

when I play the bass low I get a small sound from the coil like a rattling and when I put it all the way up( thats the only time the speaker will boom ) it'd be this shitty bass.. it does the same for both the type x and the new sub.

It has to be the amp then, I checked the ground which is connected straight to my car chassis and I checked the power and I'm getting 14volts which is good.
All the wires are in place, I checked the amp to deck wire, checked the speaker wires.. even connected the sub straight to amp without a box and getting the same problem..
What do I do?.. Since I never got my system professionally installed and alpine is hella far from me (i'm on vacation in new brunswick)

Thanks!
