whats wrong with my system?

[j0hn311]

i was in my car the other day and the music wasnt even on loud and i heard a little boom sound and the light on my amp turned red(its normally green). when this happened i thought it was the amp that was blown but about a day later the light turned green again but still nothing worked. I bought a new amp thinking it was the amp that was blown and i hooked the amp up and still nothing works. I noticed however, the subs hit really really really softly, i can feel it and see it a little bit. What would be the problem? are my subs blown? any ideas?
thanks

my guess would be blown subs

you probably blew the sub(s) .... that red light means the load impedance is too low.

well i just bought and installed 2 new 12" P2's and still its doing the same thing, just barely hitting, atleast now when i finally figure out what it is ill have 4 12"s and 2 amps haha. im guessing im gonna have to rewire everything...
