How do I put my car stero in auxiliary mode


how to put your amp in aux mode is that the question? I would think that your head unit should be taking care of the aux modes. Your amp is only going to amplify the sound sent to it it's not like a home stereo that has a preamp built in that's what the head unit does on car audio.

Have a jl audio 500/1 the red light blinks and no other light turns on. whats the problem with it?


I think you might have your remote turn on from your deck to amp hooked up wrong check that out!! I not are you familliar with the mr. butterworth crossover JL developed for that series of amp? Just like its big nrother the 1000x1 class D the built in smart crossover has many built in pretect modes. If your subs are drawing to much power it shuts down if they draw to little of ohms or to many but that 500 is 1 ohm stable so download the crossover settings from JL and go from there

Volfenhag zx 8200 amplifier cooling fan not working


open the back of your amp and see if the leads from the fan are burnt anywhere. trace them from the fan to where they are soldered into the board. if the wires appear to be fine, then test them using a volt meter. if the positive is not recieveing power you may want to solder the lead to your remote turn on.

I got power and it hits but then after a bit it stops and red offset light comes on? whats that mean


The amp is overheating it doesn't have a built in fan. This will be more occasional in the summer months. The best solution is to build a box and buy a few computer fans, install a fuse link run the positive of the fans to a remote wire and ground the fans to the chassis of your vehicle. You need a way to recirculate the air inside your amp. I've decided to remove the bottom plate of the amp, mount the amp on a board. Cut holes out of the board and have one fan flipped to pull hot air from the amp and two fans to push the air away from the amp.
You can buy the Antec and Rocket Fish fans for under $15 from Best Buy.

Earthquake mobile amplifier- fan overruns


As far as I know, no amplifier runs the fan after the remote turn-on voltage is switched off. If the protection light it lit, the amplifier is probably damaged. If it's brand new, you should return it for repair or replacement.
