Car Stereos: 2000 nissan maxima, nissan maxima, two subs

Question
I have a nissan maxima (with bose stock) and I just put two subs and an amp in. And I found out I only had one stock speaker in the top of my trunk and an amp came stock in the trunk as well. Well, I can't get my system to work and I was wondering if you knew of any diagrams or had any useful tips or could tell me if taking it somewhere just to be checked out would cost anything. Any type of response helps. Thanks.

Answer
The speaker in the trunk deck is the factory sub.  You can use the wires going to that amp to power and feed your new amp and subs.  If you would rather leave that sub hooked up, then just splice into the door speakers and power the amp from the battery.  If you have any further questions, just ask.  Hope this helps, Scott
