Question about Car Audio & Video
I have a zapco dc1100 amp that was pro installed, it is powering two jl 10w3v3s. when i got it back the bass was lacking, but present. I got the software to adjust and heighten my bass. after hooking up my laptop i was able to open the program to adjust my sound. though while tweaking the switches no sound was changing, and after a few minutes of this the bass died completely. The amp is still receiving power, or at least the power light is still lit up green. I was unable to get the sound back and ultimately gave up for the night. Have you ever heard of this problem? Please help.

This is an indication that the MOSFETs are ok but the driver stages may have a problem. Get a schematic find the pre-amp stages and test the voltages levels there as compared to the schematic. I do believe that you will find the problem in the pre-driver pre-amp atages.

Is your sub single voice coil or dual? If it's dual, is it wired in paralel or series? It's possible for an amp the heat up so fast, the outside is not hot to the touch. Also, the next time it happens, use a paperclip and short the 12+ to the remote wire on the amp and see if it comes on. Let me know, and be sure to leave feedback or I don't get paid

Check your fuse at the battery. While AGU glass fuses "look" good, when you read the voltage AFTER the fuse, you can only be getting 5 volts or so. I can't tell you how many times I have seen this.

This is normally due to clipping of your sub. Try reducing your low pass frequency to half and volume gain on your amp to 1/2. Your amp circuitry is over-heating. It's not designed to run like that. Use minimal gain on your amp and use your head unit to increase your bass. Turn up your stereo 'til you begin to distortion from there adjust your gains to your listening volume.
