20 Most Recent PPI DCX-1500.1 Car Audio Amplifier Questions & Answers

Hello montyski20,

The amp outputs 500 watts RMS into 4ohms, 750 watts RMS into 2ohms and 1000 RMS into 1ohm.

The L7 can handle 750 watts RMS (375 watts per each coil). If your L7 is the 2ohm version, you should wire the voice coils in series, the positive marked coil to the negative unmarked coil. Then connect the remaining positive and negative to the amp terminals. This gives you a 4ohm load (500 watts). If your L7 is the 4ohm version, wire the voice coils in parallel, both marked and unmarked positives together, likewise both negatives and then to the amp terminals. This gives a 2ohm load (750 watts).

Paralleling the 2ohm sub will result in a 1ohm load (1000 watts) and that is too much for the L7.

Hope this helps.

Sounds like the amp is fried, most likley in one or both of the output sections. Good luck.

the remote wire goes in between the front speaker connects. the extra spot in the middle.

Try a place online called Allied Electronics. I use them all the time things just like that.

Sounds as if you may have a bad ground. try running an external ground from the radio to a bare piece of metal underneath the dash.

you can try to open google.com type the model and diagram
