you don't need to spend lots on an amp if you dno't need power. I picked up an el cheapo off ebay for like 30 bucks just to get testing and over another barrier in my project. Turns out it works great for the stock speakers. I also found an easy solution for getting the audio around the car from the trunk. Get a sterio harness for your car. plug that in where your radio used to. on the harness connect the wires for the front and rear speakers then plug the leads from your rear speakers into your amp in the trunk. they will now power the front speakers. then just run some leads to the speakers in the rear deck as it is an easy run. No cutting of the factory harness and it works like a charm. Hope that helped.
