Subs cutting out

I 've had 2 Infinity reference series 1230w subwoofers for about a year now and about a week ago one of them stopped working. The sub just kept cutting in and out. When i pressed lightly in the center of the cone it would come back on... I checked all of my wiring and everything seems to be fine and now the sub won't work at all. to make things worse, my 1 working subwoofer started doing the same thing today. They don't sound blown at all but i know the problem lies within the subs. Any ideas???

Agree with Kev. Even if the woven lead wire looks ok, it can still be bad. I unsoldered it, clipped a lil from both ends, and re-soldered it. Works great now.

Hi i just got 2 new infinity 860w reference 8'' subs 250 rms each and pushing it with sony 600watt amp pushing it but very low sound and no bass why the othier speakers i have in 10'' hit the bass fine but...


The amp may no thav eenough to push these subs, these are top of the line subs, they probably require a bigger amp, if you are running other speakers through this also, you certainly need another amp, or a bigger one with more channels. also double check all your wiring.

Why does my 6x9 amp drop or not let the sound play at all when my subs are on? it just started to happen? they worked together fine before. i turn the subs off and the 6x9 work? but when i turn the subs on...


You probably have too much hooked up for the size of your power supply which is presumably a small car battery. You either need to get:

A) New, better bigger battery.
B) Capacitor in series with battery.
C) Both of the above.

Subwoofer buldging out problem


When speakers are wired in the wrong way the will do the "pushing out" you're describing. Basically the polarities have been reversed and if kept like this over a period of time will blow the speaker. Best thing to do is to disconnect the power by the negative on the amp and take out the fuse from the power supply. Check the wires running from the amp to the subs, negative to negative and positive to positive. I know it sounds basic but many people do mix it up! I would also check to see what channels the subs have been wired into?

Best way is to have one sub from channel 1 and the other sub from channel 2 for example. Or if its a bridged 4 channel amp, have 1 sub running from channel 1&2, and the second sub running from channel 3&4 still making sure of the polarities. Again this all depending what kind of amp and sub you have.

-----------------------------
For example;
A 4 channel (bridged) 1000W amp. 250W max per channel or 500W per 2 channels! So if you have 2 500W subs, by connecting one to a single channel will decrease subs ability due to the lack of power supplied. However by combining 2 channels you optimize the output!
---------------------------

Once you know all your wiring from your amp to subs are ok/good connections/good wires etc you shouldnt have to "wiggle the wires" to get it to work as this is just a bad connection. Also ensure that no 2 wires are touching. Make sure that the master volume on the amp is turned down. You dont need this to be on loud at all, in fact far from it or you'll risk damaging both the amp and subs!

Hope this helps!

Blown sub, butIdon't know why


if you use a right channel on one coil and a left on the other different frequencies are going in different directions in each channel thus blowing a coil or badly damaging it-z

Sub works when i push on it


the woven leads between the terminal posts and voice coil go bad. they may appear intact, but they can still go bad. I unsoldered them, clipped a lil off the ends, and re-soldered them. works great.

Hi JJerky,

I suggest we go for 2 ohm to preserve the amp and not heat things up so bad.
Your Subs are Dual Voice Coil(DVC) and 2 ohms each coil. I am going to tell you the wiring to insure you get balanced response from both Subs. We will wire the Subs Voice coils in Parallel to make them 1 ohm each. Then we will wire the Amp to the subs in series to make the total load on the amp 2 ohms. When you have series to both subs each sub gets the same current.


Example of my coding :SUB1VC1+ = Subwoofer 1 Voice Coil 1 Postive terminal.

SUB1VC1+ to SUB1VC2+
SUB1VC1 - to SUB1VC2-

SUB2VC1 + to SUB2VC2 +
SUB2VC1 - to SUB2VC2 -

AMP + to SUB1VC1 +
SUB1VC1 - to SUB2VC1 +
SUB2VC1 - to AMP -

This should give you a good repsonse.

Adjust your Bass Gain down very low at first. Also cut you LPF to about 60 hz. Crank up the volume on a bass test Audio track, Adjust the Bass Gain up unitl you get distortion. The turn it back a little. This is proper setting for your Gain.
