### My amplifier for gale 3090subwoofergot damaged, the speaker and the box still intact. I need replacement

Hi,
It will be very difficult get the exact replacement for the subwoofer you have. If you sech in the internet you will get lot of subwoofer modules. Buy one which will fit in the dimension of the existing amp module..

Check the link for sub woofer modules

Subwoofer module

This module will be perfect for you if the dimentions are correct. If not then you have to do some cuts on the box to suit the same.

### I need Dogbone bearing dimentions

The outside edge of all bearings have a maker and bearing number i.e. "NGK2604". Get the number then go to an industrial bearings company. They can look up the bearing and see if it is in stock and if not, they can look up a matching bearing from a different manufacturer i.e. " SAS3107". The actual dimensions will likely be available at the same location. By the way, most people have no idea what you mean by "dogbone". Do you mean the crankshaft main bearings?

### What car amp to use to run 2 dvc subs

You need a stereo amp that can run 400amps
continous, with an output of 4 ohms. These should
not be too hard to find and they are getting smaller
all of the time. Make a practice look on ebay.
They give you pictures and you can check the dimentions first, so you know it can fit between

### Dimentions

You can contact Sharp at 1-800-BE-SHARP (1-800-237-4277) or visit them online.

They should be able to tell you what current model is comparable to yours.

### Wires

Hi Gott Mudd,

I can relate to feeling it in the bones. You got the stuff to do it.  You should try the Alpine MP3 head units with bass boost, those are bad to the bone.

Wiring:

Amp to Speaker I like to use the code VC for Voice coil, and AO for Amplifier output.  Also + for positive.  If I say VC1-, I am referring to the first connector starting left to right on the Alpine Sub. Now I have not seen a Kicker KX1200.1 amplifier.  All I see are MRA, MRP, or PDX prefix on the part numbers. So take what I am saying as a guess. You may want to revisit looking at the model of the amp to be sure your giving the right information.

We are going for  2 Ohms. Paralleling the two subs, not the voice coils. The voice coils will be series.  Bridge the amp if necessary to get mono channel. only using AO+ and AO- for output.

AO+ to Sub1VC1+

AO+ to Sub2VC1+

Sub1VC1- to Sub1VC2+

Sub2VC1- to Sub2VC2+

AO- to Sub1VC2-

AO- to Sub2VC2-

Adjust the bass gain down to lowest until you test.

Set the Frequencies to midrange between 40 and 100hz

Your box can be ported or not. It depends on the space your have.  If you do not have much room, go Enclosed and build a box that the inside space is less than 1 cubic foot.  Make sure you give barely  enough clearance for the speaker to fit.  If you have room, Go with a box and vent it with a 3 inch Vent tube 10 inches long.
