please help with stock sub install

[wicket]

I have tried searching all over this site and haven't been able to find the help that I need. I recently replaced the factory HU in my '93 EB with a pioneer cd player with separate sub level capability(I think it uses a set of regular audio cables to connect a sub). I used the amp bypass, but now my sub doesn't work, because the sub amp was connected to the stock amp. How do I make my stock sub work with my new HU? Thanks in advance.

You are going to have to figure out the wires going into the factory amp. There should be a ground, 12 volts. You will have to plug your factory radio back in and use a volt meter to do the checking. When you find all your power wires there should be 2 wire left that should be the input into the amp. I have done this numerous times at work. It just takes some investigating. If you do not feel comfortable doing this take it to a good stereo shop.
