I want to add a sub setup behind the seats of my 1993 Del Sol. What are you alls opinions. I already have the amp, I haven't decided on whether two 10" subs or one 12" sub. The output will probably be the same, somewhat. I have a Pioneer GM-X742 Amplifier. It puts out 80x2 at 4 ohms, 120x2 at 2 ohms, and 400x1 at 2 ohms. So I can go one or two subs. All replies are appreciated. Remember space is limited, the setup is going behind my seats. Anyone with the same type setups will you please include pictures? Thanks!!
