Sub magically stopped working

[jaywood]

I was driving to school this morning, plugged in my iPhone (via USB to headunit) to play music like I do everyday...but today was different. There was no bass!
Everything was working fine yesterday, so what could have happened? I didn't change any of the HU settings.

did you check if the power cable or ground maybe unplugged from your amp? Stranded cable has a tendency to slowly break away from the typical amp screw connector. Maybe the RCA's? if they are plugged in then get a DMM and see if there's voltage coming through the cables.

I didn't have time to check much this morning. I will check it out after school. I just want to know what to look for!

I'd say you listened o loud and blew it. However.... If it magically stopped working I say get som lucky charms a few Harry potter books and a magic wand from the dollar store... Should fix it

How could I have blown it? I play it at the same volume everyday.

Can I test if it's blown? The woofer isn't moving at all when I play music

Maybe it's my iPhone cable...I'll try a cd because I have no radio :(

What all is in your setup?

Check your power connections

You do know if you don't get the plug all the way in on your phone you get no bass, right? I assume everyone who uses a miniplug knows about that

Polk sub, kenwood amp, pioneer HU

It's been working fine for over a year now...maybe something got loose.


And yes, it was plugged all the way in ;)

Well, I plugged my phone in after school and it worked. It doesn't sound the same though.

Deep bass sounds the same

Higher bass.....there seems to be a rattle inside of the box. Maybe part of the sub? I'm not sure.
