Question about Rockford Fosgate RFP3212 Car Subwoofer

Somethings Crazy

I have had two of these subs for quite some time and have not had any problems til today. Upon re-installing my system,i could only get my right subwoofer to go. I switched the speaker wires and had the same result, which proves that the speaker wires are in working condition. I then took the non-working subwoofer out of the enclosure and checked all the connections and all appeared to be secure. Im out of ideas of how my left sub could just stop working like so.

Re: Somethings Crazy

It's surprising to see one fail after such a long time, but most likely either one of the tinsel leads (between the speaker terminals and the voice coil) has broken, or the voice coil itself has burned out. You should be able to see the tinsel leads; if one has broken away from the terminal you may be able to solder it back into place. If it's broken on the speaker cone side, it's unlikely that you'd be able to solder it without damaging the cone. A break in the voice coil won't be visible; to test for it, check for continuity between the two terminals. Unfortunately, it's probably going to be easier to replace the subs than repair them.

Kenwoodxw1000f shut off after 10 sec

the problem sounds like your new sub is drawing to much power and your amp can not handle it. bridging the amp is a good way to get the full power out of your amp. But it isnt always suggested, my solution is to get a bigger amp. I install stereo systems for a living, and i tell my customers that it is smart to get an amp about 100 more watts then the rms rating of your subwoofer.

I have a jl audio 12w7 with a 750/1 hd amp and i want more bass is there anything else i could do to get more out of my sub. i was told to add a battery and another amp to my deck speakers will that help...

My full time job is designing and building sub enclosures. So you are in luck.
Anyway you don't want deck speakers and amp for more bass and adding a battery doesn't help unless you already have power problems. Adding an amp and a sub would help but can be expensive. My main recommendation would be to change the box your sub is in, designing it for your vehicle. If you are in need of bass that is crazy loud, then you would be adding subs and amps. Your amp can drive a bunch of subs if you want and it would probably be more economical to just add a sub or three. Shoot me an Email @ if you need specifications on adding such improvements.

Subwoofers won't work and they are brand new


I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.

My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.

First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.

High pitched noise comin from sub

if sound also goes away when throttle is released and sound returns when throttle is pressed down, then you have engine noise from car engine electronics. In older cars, this was quite noticeable when the cars had distributor caps. The electrical noise caused by arcing required for the spark plugs could be your issue. It is resolved with a noise filter which gets wired inline leading to your in-dash deck and power amp (if you have one). The filter can be found many places including Radio Shack and First find your total wattage draw for each component of the sound system (deck and amplifier), then divide by 12 to get current draw through filter. Purchase that size filter or larger.

Car sound system. only sub is giving off sound. other 4 speakers dont work at all

Could be bad outputs from the back of your head unit or also could be bad rca cables. Make sure the amp is on and powered.

Home theatre subwoofer

Sounds like you have a loose signal lead. Check to see if this cab be tightened if not replace the cable as this could be the cause of the problem. Over time the leads/plugs do loosen especially on subs as they vibrate so much. If it's not this then it's probably something internal to which I am reluctant to advise you on looking at yourself unless you are pretty proficient with electronics :P
