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!

How do i rebuild the voicecoil on my kicker l7 15in speaker

I dont think that kicker has a recone kit available for L7, after they started building the cone as a one piece structure without a dustcap, making it impossible to align the coil in the gap.
Myself, i have considered the possibility of using the carbon fibre maxxonics recone kits, it may need some tweeking to make it work. but will be quite strong and you could try different coil impedences, aluminum formers etc.
if you dont feel adventurous, than you might be able to send in your sub to kicker for service. i think they just send off a new sub to you, at a discount......

My amp will not turn on i think its burnt how would i fix that

Using a multimeter, check the power going to the amplifier for around 12 volts, and check the remote wire for anywhere from 3 to 12 volts. If power is getting to the amplifier and the remote wire is signalling the amp to turn on, check the fuse/s on the amplifier. If the fuse is not blown, have the amplifier checked out by a stereo shop or send it to the manufacturer for warranty repairs.

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.

My 12" subwolfer has two ports how do i install it to my amp

if it is a dual 4 ohm voicecoil subwoofer - and your amplifier is rated at a 2 ohm load - both + to the + on the amplifier, and both - to the - on the amplifier will net a 2ohm mono load.
Most amplifiers are capable of a 2 ohm bridged load.

If your subwoofer us dual 2 ohm - a 1 ohm load is achieved, but many amplifiers cannot handle this low impedence and damage will result.

Verify your amplifier's capabilities before wiring - and also the impedence of your voicecoils.

I have 3 Kicker solobarics Hooked to 1 ohm, But

It likely has a blown voicecoil - or the voicecoil is damaged in a certain spot - so when you play a certain frequency it cuts out.

Aso check the integrity of the tinsel wires - if they are loose or hitting the basket, it would stop playing.

BTW - it is impossible to wire a 1 ohm load with (3) single or 4ohm voicecoils.

Be sure your wiring is correct - or the amplifier will be the next thing to go.

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.

Need to know how to repair my voicecoils

If you have removable voice coils, you can take them off and buy new ones, otherwise, the speaker is pretty much hosed. Voice coils require too much precision to be made by hand.
