If you are going with 2 subs on the sony amp listed... they must both be Dual 4 ohm subs or single 2 or 8 ohm subs. (if you want to get full power from the amp)
go to rockfordfosgate.com and check out the woofer wiring wizard, it will help explain how to wire them. Also check out bcae1.com, it is a great website for anyone to learn more about car audio in general (or advanced).//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
