Sub Blown?

[Ryan@RhynoTune]

I had a couple of questions for the car audio guru's. I have a JL stealthbox that I think I just blew the sub on. I just started the truck a few days ago and I heard a weird sound, I turned on the radio and the sub sounded weird. To me it sounds like one voice coil is out. So to check that, do I need to OHM each individual coil, or can I tell just by checking the leads?

Is it tough to replace the sub in that box. I didn't do the install and I haven't really been into car audio in several years.

Thanks

i would check the ohms by just seeing what reading the meter gets at the wires going to the amps...if it hovers around 4 ohms your good. also push it in with your hand and see if its "crunchy"as far as changing the sub it isnt bad, hardest part is getting it out of there. changing the sub just involves removing the screws and then pulling it out of the box.

Thanks I forgot all about the feeling. I know exactly what you're talking about.

Dallas I'm running an older Alpine MRD-M300. It's a V-12 mono 300 watt amp.

Thanks fellers

Mine started sounding weird, like a little hollow. I found one of the RCA jacks wiggled loose where it plugs into the amp. Plugged it back in and it's been working fine for over a year. Might also check your ground wire on the amp. Sometimes the easy stuff will get you to disassemble the whole thing to find it was a 30 second fix! Hope this helps.

I replaced mine with a Alpine Type R.

That should be the best "fit" with the demensions on that box!!

C Dillion, how does it sound?

Also I ohmed the sub, the readings don't bounce around much, they go between 5 and 6 ohms. I thought if it was blown, it jumped ALL around.

[jvillefinest]

not exactly it would just be really high or none at all

Sounds great!
