20 Most Recent Sunfire True Sub Signature Subwoofer Questions & Answers

I think it will be most likely a semi-conductor device that is overheating. Probably the main amp device. Subs are basically mono amplifiers.

that's just likely a dirty potentiometer. (the circuit under the knob)

ebay has em usually

check the box for air leaks

The humming could be a couple things.. First try a different outlet in a different room..Make sure the RCA is firmly in place if using LFE and none of the speaker wires strands are touching if using Hi-Lvl input. Also if using Hi-Lvl you might be getting feed back from the Amp.

You either ripped your voice coil, or you have something jumping around inside (Screw, nail, etc.). You can tell of a blown speaker by pressing straight in, and if you hear a rubbing noise, then your speaker has disconnected from your voice coil. Mickey mouse jobs include Krazy Glue, but It's touch and go

maybe its an issues closely related to the fuse they are a fail safe so somethings failing and the fuse is your first indication ok just me but its not the fuse causing your problems i would say its a 95% chance its other issues

you can go to a hardware store and silicone caulk that is black, make sure it is flexible type. clean surface with rubbing alcohol and a cue tip to prep surface area well, allow alcohol to dry,apply silicone front and back of cone evenly bout 16th inch thick and let dry for full cure time on directions of silicone caulk tube. sub will work awesome. ive done this on many car subs of high amps and never had it fail. hope this helps you alot, i understand how it feels

phone an electronics parts provider in your area and ask who re -cones speakers.There are usually a few that do that in all major areas.A shop like that will be able to repair it by putting a new surround on it.

you may have a groung problem in the wireing of your home, buy a 110 ground tester at home depo and check your home wireing

Before we get too committed to a direction to go, or embark on unnecessary surgery, can we establish that we KNOW it's the speaker and not the amp or source? Perhaps you could swap it with the other one.

Back to basics: is this a sudden-onset problem or did it always behave like this? Try swapping locations with the other one. Bass response is a lot about location, location, location. Standing waves, self-cancellation, phasing. All players in this game.

Capacitors either fail spectacularly or in a very subtle way. Every once in a while, they'll explode, in which case it's very easy to spot the one that needs to be replaced, but generally they fail internally, with no visible problems.
(very old units used a wet electrolyte, and the capacitors simply dried out inside)

If you are able to determine which cap is bad, you will definitely need soldering skills to replace it - no way around that.

Soldering isn't difficult to learn, but I can't help you over the internet. :) If there's a craigslist in your area, you might try posting to the "Wanted" section to see if someone can teach you how.

Best of luck to y

big red
if its that old then you should keep it look for spare parts from other subs just make sure it is worth it

Hello

You need to build or buy a certian cable. The cable goes from RCA to mini jack. You plug the mini jack into your computer and the RCA into the input of the sub. I really hope this can help.

Best regards

The first thing to always check first is the fuse. This will probably involve some disassembly but it is alwayst the cheapest fix and a constant issue.

send this baby to the manufacturer, great service at fair prices...they will often repair for free
