New Alpine typer-R not working

[Hustler00 10+ year member]

Just got another SWR-1223d and when i got it it was working perfectly fine on the first day. on the second day, i was coming home from school and it just stopped. i check all the wires to see if any were loose but came up with nothing. The amp is on so it can't be that. And it cant be blown because it doesn't make any scratching noises whenever i push on it. I tried using different channels on the amp to see if that would work but sadly it didnt. Any Suggestions?

oh btw, the only problem that i know of is that my battery would turn off randomly and turn back on, that may have caused damage but i don't think it would be severe enough to where it would stop working all together.

And to add insult to injury. Now my front speakers gave out. Anyone know that the problem is?

Make sure your grounds are actually tight and secure, not barely hanging on with enough force for it to easily be knocked off. Check RCA's also.

take the subwoofer speaker wires and touch a AA battery to the positive and negative. If the sub pops in or out, the coils aren't blown. If you have a DMM, you can just use that.
