Was in a accident an amp came loose an ripped out remote wire that's on a separate switch, repaired remote wit sodder jumper an amp powers up again! But jus makes a crackly noise through the sub an...

Hi There. Any impact damage that was able to rip your ampifier loose may possibly have done some damage inside the amp. I would reccomend that you disconnect your amplifier and take it in to a reputable dealer to be bench tested. They will be able to give you the diagnosis.
P. S. If ypou feel that you are technically minded and are able to solder proffesionally, then open your amplifier. Check the board for breaks or hairline cracks under a light. Repair if any are found. Check for broken solder joints on the reverse side of the board. Repair any that you may find. Stripping your amplifir is NOT RECOMENDED and WILL VOID your warranty.

Hope you solve your problem. :)

I've been running a kicker kx 800.2 and it has worked until now

Hello highryguy420,

It sounds like one or more of the output components is failing on the amp. You can contact Kicker support directly for instructions to return the amp for repair: . Alternatively, if you have a local car audio shop that does component level repairs, they could perhaps save you some money and time.

Hope this helps.

Won't stay on, turns off by itself

With a 1.5 Volt Dry Cell (AA Size), connect two pices of wire with the Cell. Momentarily touch the wires with speaker several times. It should produce click sound when wires are touched. If not then speakers are defective and need repair. Do not touch the wires for more than a second, touching the wires for a long time may damage the speakers.

I have a sony 1200 watt amp and if i play it for a while it shuts off for 45 secs then back on and repeats cant figure it out any ideas???

hey i kept having the same problem with mine
it does it cause it is hot so its a built in safty feature
make sure yr amp is not covered in any way or against the seat or something like that.

if you want also you can put some spacers between it and where you have it mounted with some longer screws obviously, and pices of ply wood or some htink of that nature for better air flow all around it. if you really want it to look good make the "feet" as i call them out of 2 3 pieces of 1" ply wood. say 2"x2"
stack and glue each layer together and then wrap them in some carpet to match yr sub box.
if then it still does it as said b 4 turn down yr knobs a bit i have mine at 3/4 of turn and bridged it sounds great and never shuts off any more

Good price

Hello smoot_dog,

Well, you did not specify whether you have the 2 ohm or the 4 ohm versions of the L7 and that will impact your choice of amps. But with 8 voice coils and 4 subs to work with, you certainly have lots or potential configurations.

If your subs are the 4-ohm version, I would recommend the Alpine MRP-M1000. Currently it is on sale at for $347.00. With this amp you'd wire the voice coils in parallel (2 ohms), wire each of the 2 pair of subs in series (4 ohms), and the resulting pairs parallel to the amp for a final load of 2 ohms.

If your subs are the 2-ohm version, I would recommend the Rockford-Fosgate Punch P1000-1bd which is stable at 1 ohm. Crutchfield sells it for $349.99. With the Punch and 2-ohm voice coils, you'd series the voice coils (4 ohms), parallel each pair of subs (2 ohms), and then parallel the resulting pairs to the amp for a final load of 1 ohm.

Either of these amps will provide an honest 250 watts RMS to each L7. They'll not only rock your vehicle, they'll rock the pavement.

Jl 500/1 no output audio

You can send it to JL Audio and they will fix the output stage you toasted and will also perform any mods or upgrades to bring it up to spec. This will set you back $ 180.00 plus shipping cost to send it to JL. I know it's expensive but you damn near get a whole new amp to rock your world. mark..

Cadence z1200 stays in Safe Mode!

If the subs are rmoved from the amp (wiring), does the amp still go into protection without them hooked up? If no, shorted sub, if it still des, unplug RCA's, does it still go into protection? Also check voltage. Make SURE you have greater than 12 volts AT THE AMP using amps ground to check the power AND remote wires. Hit me back wth an update.Those amps rock.
