Ok well since I had posted my question I have been searching internet and looking at different 8" subs for this box. WOW just so many to choose from and to find the right one. Single voice coil 4 ohm, dual voice coil, 2 ohm, coil dual 2 and 4 ohm, ohm and coil, this magnet and that power rms, Man oh man am i confused. I have seen many decent or maybe not, brands from anywhere from $50 to say $90 is a good place to start looking.
I have Seen, Rockford Fosgate, RE Audio, JBL, Planet Audio, Lanzar, Kicker, MTX, Infinity, SoundStream, Cerwin Vega, Polk, Pyle, Boss, AudioPipe, Crunch, Power Acoustic, Massive Audio, Sundown, MB Quart, Image Dynamics, Bass Master, (oh no bass master made that up) Get my point? Many Many brands. What oh what will work well and sound good for years to come.
