How do I install extra speakers on my stock 1993 Chevrolet S10 Tahoe?

[WheelMann]

My 1993 Chevy S10 has the stock speakers in it, and i'd like to add one extra speaker behind me in the ext. cab.
How do I wire it to the stock stereo? Or can I? And where do the wires connect to?

it sounds like you dont know much about the subject so you need to go to somewhere like bestbuy and they will tell you what you need......
and it would be hard and alot of time to explain how to hook a car system up on here so go to best buy if you buy the car audio there they will hook it up for you...
you want to add a subwoofer you need a car amplifier to supply enough power to run the subwoofer....
