check your settings on your stereo and the amp make sure you have changed to 1 ohm on the amlifier for a briged connection to a subwoofer and change from lpf to hpf on the amp there should be a switch.

Storing as in Distortion? If that's the case lower the output gain from your amp until it is suitable to you ears. It might be all the way open, besides this should be adjusted system to system.

If the amp uses TIP35Cs and TIP36Cs, those will be the output transistors. Measure the resistance between legs 2 and 3 for each of the output transistors. Do any read near 0 ohms?

You will need to call the manufacturer, ZAPCO - 209-577-4268, or email them at tech support [email protected] , in order to purchase the part you are missing. It is possibel to hard wire the RCA parts you need and creat a homemade fix, but in all honesty it is not worth it, and it will probably introduce a lot of interference in to the quality of your signal path rendering it a bad option. Give them a call / email. If they will only sell the part to a dealer, call Car Depot @ 615 - 269-8080 and they can have the part purchased and delivered to you for a small fee. Good luck.
