I was looking to buy a S-10 ext. cab. My question is where do I fire the subs at. should they be facing toward me to get the most sound? I know I like the sound in my trunk of my car I have now. They are facing toward the back of the trunk. Is there a certain way to get the best sound in a ext. cab truck to get the most of the subs? Any ppl that have had prior experience with this would help alot.
