Question about Rockford Fosgate RFP3212 Car Subwoofer

1 Answer

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.

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.

Upon entering any game the system


Call (800-345-7669)

Sony Network is experiencing sporadic outages in certain areas today.

It is reported to be "scheduled system upgrade" to the network servers - be assured you are not the only one facing this issue.

No UP time has been announced by Sony - they are working to get the system up and running as soon as possible.

The problem is not on your end.

Keep trying to connect.

Subs cut out at low volume no matter the settings


I'm not a complete audio expert but it sounds like somethings over heating or you have a blown out put bridge.

Subs fading out briefly but speakers working fine


Holy mackerel you have a ton of power i bet that ****** is loudddddd-sounds like your charging system isnt quite keeping up with the amount of current draw that your amps can pull.Upgrade your alternator and look into a dual battery system using an isolator-that way your alt will charge both batteries but your amps will only pull off the one battery-you can look online into how to set that up its not that hard for someone that has managed to install the gear that you already have- Some folks if not most would encourage you to get some sort of capacitor to store power blahblahblah-BUT a dual battery system has waaaaayyyy more storage capacity than a capacitor does-check out the pro competitors online they arent using capacitors to run their stuff they use banks and banks of batteries to get their power-brother you need more juice

Subwoofers won't work and they are brand new


Hello,

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.
