Making a high powered substitute voicecoil

I have the wires and the former but not the adhesive. Recently my Jlaudio 12 w0 burnt out. I usually repair speakers and make coils for low wattage speakers for home use. I use epoxy to make the coils for these speakers. I tried making a coil for a high powered car speaker using epoxy but the coil failed at an early stage. Does anybody know what kind of high temperature adhesive is available to make high powered voice coils? I want to know the name of the best adhesive available for attaching copper wires to kapton formers that can withstand searing temperatures(above 600f) and thermal shock. Also tell me how can I access this type of adhesive. Please help!

What's the board substitution relation among different versions?

The TN52NS3 can be created as NS3 on the NMS. The former can substitute for the latter, without any software upgrade. After substitution, the TN52NS3 functions as the TN11NS3.
The TN56NS3 can be created as 55NS3 on the NMS. The former can substitute for the latter, without any software upgrade. After substitution, the TN56NS3 functions as the TN55NS3.

My head light went out. Checked the bulb with 12 volts of power and it worked. Checked the fuse and its not burnt. But there is no power there. Either side.... Now what do I do

It sounds like a headlight relay might have gone bad. They're usually in a fuse box under the hood. Do you get high beams and/or fog lights? If everything but the low beam went out, then you may be able to find a wiring diagram online for your make/model/year of car and start tracing back from the bulb until you get power.

When you get to the circuit where you get power TO it but not OUT of it, then you have found your culprit. I am still guessing headlight relays. If you have two of them, swap them and see if anything changes (like, lows work, but not highs)

Just got 84 lasharo rv ac blower dont work cant find fuze

If a GM chassis and problem is dash air, remove the power wire from blower (under hood) & apply 12 volts directly in order to confirm blower even works. Next, pull blower relay harness & check for arcing/burnt wires & contacts (usually the culprit this year GM). If good, trace wire to relay and check for 12 volts at relay (be sure to use a test light) and do this across the ground and power wires to relay and, relay to blower. Bad grounds and burnt contacts on relays are more of a problem than fuses during these years.

In my display is says 3-03 when ever i plug in my rca cables and no sound comes out?

From Page 7 of your manual... this is indicating a grounded speaker wire (blown voicecoil).

It has shut down to prevent damage. Disconnect the speaker wires from the amplifier and power on the amplifier again. If the error persists - you will need to have the amplifier repaired.

Check the voicecoils for proper imedance.



Wiring diagram for dual voicecoil subwoofer

To wire a DVC subwoofer, treat it (in the diagrams) as two seperate speakers, called coil one and coil two. This makes things easier.

To wire them up, wiring them in series would be safer, but if the amp is 2 ohm stable, put them in parallel. Look up dual voice coil wiring in google imagesfor more information and pictures.

Bright lites indicator out, recently installed head lite modulater

The "high beam indicator" lamp gets it's power from the high beam wiring to your headlamp. Usually, it's wired in parallel with the high beam filament. The high beam filament is usually powered by the white wire going to the headlight. Evidently, this circuit has been bypassed by the modulator.

Sub cutting out

500W x 1 @ 2ohm

How did you "switch the sub from 2ohms to 4 ohms"?

If you have the swr-1222d as listed, your only options are wiring 1 or 4 ohm, as it is a dual 2 ohm voicecoil.

If it was wired @ 1 ohm - you may have already done the damage to your amplifier - as it is not rated @ 1ohm mono.

There are 3 reasons the amplifier will go into protect mode while playing...
Thermal - overheating due to too low impedence.
Ground Loop/Short Circuit - Blown voicecoil, bad amplifier ground, tinsel slap, etc.
Overload - Impedence not within specs.

Disconnect every wire (including RCAs) from the amplifier. Reconnect only power and ground - make a short wire to loop from power terminal to remote terminal.

If the amplifier stays on without turning off - remove the jumper, add the remote wire, and try again.

If it turns off - the problem is internal and needs repair.

Still on? plug in 1 rca, and re-try.... then the other.

Still going??

Now use an Ohm Meter - or Digital multimeter set to ohms 20, and check both voicecoils. They should read 2ohms +/- .5ohm.

If they are OK, wire up the 4ohm load (series the voicecoils) and turn the gain on the amplifier to 1/2.

Retry -

If the amplifier continues to fail at higher volumes - the thermal protection relay has become weakened because of your improper wiring, and will need to be repaired to solve your issue.

Trying to figure out what kind of amp i got amercian pro vs-3507?

The VS3507 Is a class D monoblock.
Your optimum wiring for this amplifier is a 2 Ohm load - so it produces its full potential power of 350W RMS.

To Achieve a 2 ohm load, the most common load is one of the following...
(1) Dual 4 Ohm Voicecoil Subwoofer Wired in Parallel.
(2) 4 Ohm Voicecoil Subwoofers wired in Parallel.
(1) Quad 2 Ohm Voicecoil Subwoofer wired in Parallel/Series.
(1) Single 2 Ohm voicecoil subwoofer.
