I just got 2 phoenix gold octane r 10" subs and i was wondering what kind of box and how big it needs to be

SOURCE: wiring diagram

The LEd wires need a wire run from the speaker to the Fuse block in your car. The small Red wire from the LED will be the one that hooks to Swtiched 12 Volts supply on the fuse block so that your Led Turns on when you turn the keyswitch on. The Black wire goes to ground, or to a metal part of your cars body, probably the same point where your Amp is Grounded.

The Octane R10 is a Single Voice Coil or SVC.
AMP+ to Sub+
Amp- to Sub -
Use 12 guage wire.

are you gong to use this in your house or car?? any type of enclosed box air tight.. will do if your useing it in your house a box you can face the cone faceing down would be good with a port in the front about 3in would be good. be sure to purchase a cover for the speaker you dont want the cone smashed .you dont want any air leaks .. you can go to any car stero shop and have a box built.if you have good wood working skills build it your self 1/2 in partical board works ..you can also get the port tube at like a raido shack.and speaker port for conections weather it be rca or speaker wire type
do not nail your box wood glue is best
