Take off the outer ring then take a razor to the under part of the rim . carefully cut the sillacone glue from the metal rim .After that remove the coil fin the same way . find the wire and take really thin solder wire and use a very small amount to repair

I need to wire 3 woofers but 2 are dual voice coil and one is single voice coil

sure, if you wish to wire them all together, wire the first dual voice coil subs first voice coil negative to 2nd voice coil positive, second voice coil negative to single voice coil sub positive, and single voice coil negative to 2nd dual voice coil subs 1st voice coil positve (again with the second dual voice coil sub, run the first voice coil negative to the 2nd voice coil positve) your speaker leads will be attatched to first dual voice coils 1st voice coil positive, and 2nd dual voice coils 2nd voice coil negative)

Remove main battery and try again, if no! sub out the ram memory one at a time and test each, if nothing! the DC jack in the laptop is a common source of trouble. The computer must be dismantled down to the motherboard level to attempt repairs.

How do i power up my acer ferrari 4000

Remove main battery and try again, if nothing! check power adapter for correct voltage, If okay! sub out the ram memory one at a time and test, still no change! the DC jack is often the source of trouble and the laptop will need to be dismantled down to the motherboard level, the DC jack will probably need resoldering.

Infinity 1250 watt dual voice coil wiring diagram

how you wire it depends on your amp, I assume that the sub is a 4ohm DVC from what you have provided.
If you have an amp that can handle a 2ohm stable load you can connect one voice coil + and - to the amp and then run wires across the sub to the other side + to + and - to -

If your amp won't support 2 ohm you have to run it at 8ohm, to do this you connect from the amp to one + and to the - on the other voice coil on the sub, you then run a single wire between the + and - terminals .

Below are some images to help

Parallel (2ohms)

I need to see a wiring diagram of an MPX 210 speaker box. My brother-in-law bought one from a friend and someone completely jacked the wiring. I just need to see how it should be wired. Pictures would be...

It really depends on what subs you are mounting in the box. If you are mounting single voice coil subs, it's easy. positive of the sub goes to positive on the inside of the box and the negative of the sub goes to the negative of the box. Then you would repeat the process for the other sub. Then wire the box to the amp using the push or screw terminals.

Now if you have dual voice coil subs, that's where it can get tricky. You really have to know what amp your using and what ohm load it can handle, and how many channels you will be using.

I'm going to give you an example that has two dual 4 ohm voice coil subs. Let's assume you will be hooking them to a 2 channel amplifier that is 2 ohm stable.

wire the positive of both voice coils to the positive post of the box. then wire both negatives of the voice coils to the negative of the box. Repeat the process with the other sub. This is called a parallel set up. Two 4 ohm voice coils wired this way will produce a 2 ohm load. since your amp is 2 channel, you will hook the positive and negative to the positive and negative of one side of the box, then repeat with the other channel to the other side. This will allow the most power to come out of a 2 ohm stable amplifier.

If you have something other than the equipment I gave you an example of, repost with your equipment specs and I will walk you through it.

Where is the cheapest place to find the cables i need to hook up the smaller speakers?

A second hand store/pawn shot. The cable is a proprietary design and you cannot replace it with something else unless you are willing to dismantle the sub to take out the wire connectors and join them manually.

Mirage LF 150 Sub Woofer. sub not working

within the sub amplifier is an electronic amplifier, that is shorted and blown a fuse. This is all internal. If you can dismantle this module, I suggest do so and any electrical/electronic individual will identify the part needed. you could also check on a replacement module-complete.

Very minimal sub-woofer power

The speaker is most likely blown out, and if it is there is no way to fix it, you will just have to replace it

Subwoofer is crackling - maybe blown? Was

Crackling is usually a sign of a blown speaker or a misaligned coil.

Both can be very difficult to fix themselves.

However you may be able to buy a new speaker .

You would have to dismantle the sub and remove the broken one first.

A goo hi-fi shop or even musical instrument shop may be able to help you with that.

You would need to know the impedance of the blown unit along with its frequency range. That information would usually be in your user manual.

Its not a difficult job but if it is a powered sub then be aware of electrical hazards and ensure it is disconnected from all sources before attempting any work.
