Question about Sony 12" Single-Voice-Coil 4-Ohm Subwoofer

1 Answer

Distortion from an unboxed 12''

I bought a sony 12'' 1000W unboxed but itched to test it, so i hooked it up to my 350W amp only to hear distortion almost like a ratling coming from the sony hexagonal emblem in the middle of the speaker...? is this sound because its unboxed or because it might be broken?

Hook the leads up to a wire connected to a 120v wall outlet and the problem wont bother you any more.

I have 2 sony xplod 4ohm subs rated 350w rms and 1200w max, i have them in really shallow boxes because i drive a single cab toyota, i know these subs **** but i do also know that they can hit alot harder...


the premier amp is better since it has a better rms rating (360w total or 160w each sub) than the eclipse (280w if you bridge all 4 channels which isn't possible but 140w for each speaker bridging 2 channels per speaker). Neither are going to push your subs but if you get another amp wiring kit and use one amp per sub they will sound a lot better and you could just hook both power wire and ground wires from the bridged channels to the power and ground terminals for the sub. That would be my suggestion since the subs are rated at 350w and each amp is 280w and 320w which will push but not blow the subs.

2 NTX-6812's. need box and amp.


if your subs are dvc 1000w max and 500rms wiring up to a 1 ohm load you would need a 1000w max 1 ohm stable amp. to put this in a pickup truck, i would not put them in a box, i would get 2 12inch tubes to put them in. cause a wedge truck box would make your system sound like garbage and will be distorted, your sql will be poor, basically you would need the right amount of air space for the subs.

Best way to connect a 15'' kicker cvr15 4 ohm dvc [single sealed box] and a volfenhag zx-4712 1000w 12'' 4ohm+4ohm dvc to my pyle 885 1000w 4 ch. bridgeable amp and how to wire the voice coils that are in...


best way is to just run the volfenhag with a set of wires for 2 channells(one set per coil) left and right @ 4 ohms per channell. The CVRs you can parallel the coils(2 ohms) and run a set from each sub to the amp in stereo left and right. This will give the kickers a little more juice than the 12 but should be fine.

No sound from sub


simply give it a 2 wire signal and you should hear something! if not then depress the cone lightly back and forth, if you hear alot of scratching/scraping sounds, prognosis in not good.

What duz level adjustment do


Hello,

The level control controls the input level coming from your head unit (receiver) to the amp.

Your Sony users manual is a little vague on how to best adjust the level and other controls.

Here is one method that some installers use and works well with most amps.

Most 10" subs sound best between about 80-100hz and below, so start out by setting the LPF at about 80hz. The HPF will not be used. Next turn the bass boost and gain all the way down. Turn on the radio and set all tone controls, bass, midrange, treble to flat, usually "0" on most head units. Turn the volume up to approximately 3/4 volume level or just until you begin to hear distortion. Now, back the volume down until the distortion is gone. Next turn up the gain control on the amp until you hear the subs start to distort then back the gain down until the distortion disappears. Next turn the bass boost up again until the subs begin to distort, then either back the bass boost down or back the gain down until the distortion is gone. You may need to play around with the bass boost and gain controls to get exactly the sound you prefer.

Hope this helps.

12w3v2 Started making distorted bass noise at low volume


Connect each speaker coil one at a time to a square 9 volt battery and watch for the cone to move.

Also try hooking another speaker to your amp just to make sure the noise isn't in the amp.

You can use a 9 volt battery to test wire polarity also. Hook up the + wire of the speaker to the + terminal of the battery and the - speaker to the - battery terminal. If the speaker moved UP or OUT then the wiring is correct. If it moved IN or DOWN then the + and - wires are backwards on the speaker.

Also if you have two or more speakers hooked together test all the same way while they are hooked to each other. ALL of the speakers need to move in the same direction at the same time.

Clipping causes more speaker damage than anything. "Dirty Power" can happen in good quality amps too. The gain control is to match the voltage between the headunit and the amp. It is NOT a volume or boost knob. If you overdrive the first stage of the amp and then clip it damage will occur to the amp and speakers at some point.

Hope this helps.
