Just recently I ditched the stock head unit and went with a Pioneer AVH-P3200DVD. Everything works great but now i want a sub. Nothing serious, just something that will improve the overall music experience. Everything speaker wise in the car is stock. I want just one sub in the trunk of my convertible. What should i go with? A 10", 12"? What amp, wiring, etc. I have no knowledge of audio whatsoever. Are there any premade box's that will fit on one side of the trunk? thanks:beer:
