Dead sub right?

Okay so my bass setup is an Alpine M450 amp @2ohms from an Alpine 12" Type-R. Yesterday I heard a kind of pop sound during play and then now it seems like my sub only plays its lower range with any volume.

So I pulled the speaker wires from amp to back of box out and put a DMM to the back of box and it's reading 9.5ohms and I also noticed when a jostled box while reading ohms its fluctuated all over but then came to rest back at 9.5ohms after box isnt being jostled.

So Im guessing this 9.5ohm reading when the dual voice coils are wired to give 2ohms to amp means my sub is blown right?

Maybe a loose wire inside the box? Take the sub out of the box and test the sub itself.

^^^ x2. Get a battery, doesnt matter which kind, C, D, AAA, 9 volt... and do a test by hooking up wires to your sub and then holding the neg side to the battery and then touching the pos.

^^^thought that was just to make sure the coils were not wired out of phase

Okay so that was correct the positive terminal in the box was loose and upon close inspection the heatshrink type insulation on the connector had bubbles in it like it probably had gotten overheated due to that loose connection.

So it does sound quite a bit better but still in certain songs I can tell its not the same.

Such as "Stay Fly" the more big boomy holding bass notes during the song dont seem like they are hitting and holding the same

Is it possible with that loose positive connection that it messed up the sub and partially took out what seems to be its upper freqs?

It's alright man,that song doesn't have a good bass line and doesn't hit hard anyways.

I think this forum is known as Ecoustics not E-opinions.

Well opinions on that song arent necessary I'm just telling you that the boomier part in that song and not the separate bass notes dont seem the same, but i guess the best way would be to hook the lappy up and start playing different frequencies and see if any are overly quiet

My bad, just tired of seeing most of Robs posts being either putting someone down, negative criticizing, or something simply to post. This is a key example of what caused ecoustics to become what it is. Not a single person but multiple people doing so.

What you said was more than an opinion and was used to make him feel ignorant. Most of your posts seem to do that to people. And by the way, that post by me was simple because I am tired of you thread dumping in mine. I'm sure many other people can agree with me. You know your stuff yet would rather post something stupid rather than help. Thanks again Rob :-)
