Ok I have a 94 dodge dakota extended cab and i was going to take out the back seat(screw my friends system more important) and i was looking at building a 2.5 cube sealed box for the 2 shivas and theyd be run off a newer model kicker kx600.1...i am looking for mostly sq but spl would be a nice little bonus...do you think this setup would achieve good results? from what i hear a good sounding system is a little tricky in a truck...any tips?
