Software zapco amp

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.

I have a jl audio 500/1. I had the amp professionally installed. The amp played for 2 days and no it has no sound but the power will come on. what could be the problem. I have new rca jacks, 4 guage power...


Go back to where you got it installed and ask them to fix it.

If you don't want to do that I would recommend going to another good car audio shop and getting them to check it out.

You can test it yourself by hooking up an iPod to it using a Headphone to RCA cable.. test at low volume first.

Bass only going to rear speakers. How do I get


Hello michaelandta,

Check your filter settings on the front channels. It sounds like they may be set to "high pass" which would eliminate the bass frequencies. If you are using the amp to power normal speakers, it's usually best to set the filters for "full range". If the amp only has "low pass" and "high pass" settings, turn them both OFF.

Hope this helps.

JL Audio 1000/1 hook up to alpine type x


it is all up to the user, you can start by turning the input up slightly, I would not go over halfway because it usually starts to distort, then the bass boost up till they distort a little then back down a quarter turn.

Jl audio 10w6 x zapco350


These subwoofers are dual 4 ohm voicecoils.

Parallel wiring the 2 voicecoils would net a 2 ohm mono load.

Connect both + on the sub to the + on the amp.
Connect both - on the sub to the - on the amp.

Many professionals simply jumper the 2 + and 2- on the sub.... then run 1 set of wires from one of the terminals to the amplifier.
