[Jetts]

Well im running a Rf punch 150s amp bridged at 150x1 at 4 ohm with a 300 watt wiring kit, pushing a Rf punch z 10" well this morning while driving to school my sub stopped hitting and later on today it frequently just started hitting and then would stop

tonight after work i redid all the connections made sure they are good

im always getting power to the amp when car is on, checked the crossover and nothing happened

really tickin me off cause i love just the little bump this cheap once effective system gave me

i have had this system for probally less then a month and i have had no problems up until now

thx for any help

You should check on the backside of the cone of the speaker. My friend had the same problem and it was his voice coil. Make sure your voice coil isn't touching the cone, if it is then you've probably already burned the voice coil and the sub won't work. The frequent yet nonconstant bass is from the coil touching the cone. You can either have somebody fix the coil or you can buy another sub.

[Jetts]

figures i'll have to check that out

thx for the help

[AirAllen01]

No problem. Any more questions just ask.

[Jetts]

will the coil be stickin out or what should i look for?

thx

[AirAllen01]

If you look at where you connect your speaker wires to the sub, running from the sub to the back of the cone there will be a couple of wires, one from the positive and one from the negative. If one of those wires is touching the cone anywhere other than where connected then it will cause a short in the coil. There should be a black mark on the wire and on the back of the cone where it was touching. If the sub is DVC, then check the wires running from both connectors.

[Jetts]

none of the wires are out but there are black marks in like the middle of the wires

[AirAllen01]

That's what I was afraid of. Sorry man, but your voice coil is fried. You'll either have to take it to a professional to fix the wire, but most likely you'll just have to buy another sub, cuz this one's not working any more. Sorry again. On your next sub, if you wrap these wires in electrical tape, at least where the wire will possibly touch, or the whole wire, it will keep the wire still and will also protect from this happening. I had to do that on my Audiobahns. If you have any other questions feel free to PM me if you want and I'll help the best I can, or you can ask any one of these other fine qualified stereo people.

thx for all the help
that was the problem hooked up this shitty ass jensen that was laying around in my garage and it works so yeap it was the sub fuck me not another one

[AirAllen01]

No problem. Sorry about the bad news. Are you thinkin about buyin a new one? If so, any ideas on which ones. If you like the bass of that sub, then go for it again, just take the neccessary precautions to prevent the same thing from happening again. If you wanna try something new then you can go with Memphis, MTX, and I hear the Alpine Type-r is a pretty good sub also. Just a few suggestions.

trying to figure out the cubic feet of air and the depth of my box to get a infinty reference

[AirAllen01]

Sweet choice. Infinity has always been a pretty good brand to go with. Good luck.

[Jetts]

found the depth it is like 6.63 and .50 cubic feet of air

but now i cant find a crutchfield mag to look at the specs for the sub

[AirAllen01]

And Crutchfield says, Reference 10' : Depth : 5 1/2 Sealed Box : .45 cu. ft. Ported Box : .68 cu. ft.

[Jetts]

really only cost me 15 bucks

stupid restockin fees
