SOURCE: dual voice coil wiring to class d amp

The easiest way to think of wiring voice coils and subs is this:

  • Two items of the same impedance in parallel = Half of the impedance
    • 4 ohms in parallel with 4 ohms = 2 ohms
    • 8 ohms in parallel with 8 ohms = 4 ohms
  • Two items of the same impedance in series = Double the impedance
    • 4 ohms in series with 4 ohms = 8 ohms
    • 8 ohms in series with 8 ohms = 16 ohms
In this case, you want to wire two subs, each with dual 4 ohms voice coils, so that the total equals 2 ohms. Your options are:
  • DVCs in parallel, 2 subs in series = 4 ohms
  • DVCs in series, 2 subs in parallel = 4 ohms
  • DVCs in parallel, 1 sub = 2 ohms
With two, dual 4 ohm subs, you can only have 1 ohm or 4 ohm total impedance.

SOURCE: c.b.radio-power won't come on.(red & black wire show short!)

Hi,
The fault is probably at either end. Yes, it could have been reversed, but most radios are easily protected against this.

If you are getting no lights or anything when keying mic, then there may be an inline fuse along the cable. As you are getting continuity, open the case up, and look for any evidence of heat at the components nearest the power supply - particularly the protection diodes - Black cylinrical components with a silver band.

You really need a meter or scope to go in much further, and check supply voltages between components and -ve, and downloading a copy of the circuit diagram will help this.

The other main fault is usually the output power transistor - which needs a sink for all the power getting thrown at it. If you remove the antenna, it can quickly overheat and fail.
Both components can be checked in-situ for voltage (or not) but the output can only be tested with a scope.

Of course - the "on" light could have blown, so may be functioning without indications, - but I doubt it.

Also check Mic outputs on the plug to make sure that is working. Some units won't function if this is disconnected.

Unfortunately, those units have a circut board at the power source and if there is no fuse you more than likely destroyed that board. Take the casing apart (the part attached to the boat) it should be two halves. That inital board you see is probably what is destroyed. Of course before i did that I would look for an inline fuse near where the cables attach to the battery or under the unit in the nose of the boat. There is nearly always a fuse if it came from the factory or dealership with the unit so i'd play a little extra hide and go seek for that before doing anything else.

Best of Luck

SOURCE: need to charge 12v car battery

Hello,

If battery is out of the vehicle, connect positive lead to positive terminal and negative lead to negative terminal.

If battery is in the vehicle, the proper way to connect leads depends on if it's a negative-grounded or a positive-grounded vehicle.

Here is a link to the manual for this charger.
Click where it says "Get This manual" (it's free).

Scroll down to pages 4 and 5 and it give detailed instructions on the proper way to connect leads and a lot more. It's a good manual to keep for future use.

I hope this helps.

Wiring diagrams for clarion dxz535 car stereo


Here's how it goes:
Speaker wires:
grey=right front pos.
grey/black=right front neg.
white=left front pos.
white/black=left front neg.
violet=right rear pos.
violet/black=right rear neg.
green=left rear pos.
green/black=left rear neg.
red=12 volt switched power source
yellow=12 volt constant power source (direct to battery)
black=chassis ground
orange/white=illumination (switched source,not to head light switch)
blue/white=amp turn on lead (to remote turn on lead of amp)
blue=auto antenna (switched power source)
brown=phone mute lead (to cell phone mute lead)
RCA connector leads:
grey lead:
red=right front
white=left front
black lead:
red=right rear/right rear subwoofer
white=left rear/left rear subwoofer
(connect to external amp)
red lead:
red=right aux input
white=left aux input
(connect to external unit)
green lead:
red=right dual zone output
white=left dual zone output
(connect to wireless head phones)
That should be all there is. on the yellow that goes direct to the battery you need to use an inline fuse holder with 30 amp fuse.
