Confused on what this switch is?

[waterboy 10+ year member]

I think i must have missed something in the ad. I was looking for a good, slightly used set of 12''s for my boat install. Went to town today and picked them up..

They are the Infinity 124.7 12" subs with a ported Memphis box. On the back of the sub where the wires plug in theres a switch that says "2" and "8" and is selectable between the two. I didnt see anything about this in the ad.

Now Im confused.. Will my 2000 watt 2 channel amp work for this? How will I hook them up? I went through the wiring diagrams on here and none of them mention this switch..

Heres the specs on the sub:

Speaker Type assive

Speaker Diameter :12"

Nominal (RMS) Output Power: 350 Watt

Response Bandwidth: 18 - 250 Hz

Input Impedance :2/8 Ohm

Sensitivity: 90 dB

Magnet Type: Neodymium

Connectivity Technology: Wired

Additional Features: Dual voice coil

Any help?

switch for 2 or 8 ohm mehbeh?

that's what i'm thinking, but how is that possible? it switches the wire when you hit the switch?

Car Audio & Electronics got their hands on a new Infinity Kappa Series 124.7w and put it through the paces. They ended up giving it an above average score of 70.5 out of a possible 100 points.

The most promising feature on the new Infinity subwoofer is a simple switch to adjust the resistance between 2 ohms and 8 ohms (there is also a dual 2 ohm model available). I know similar things have been done before, but it is nice to see this being employed more often just for simplicity.

this is the closest thing i can find online to a pic of the rear of the sub but you can barely see the light blue switch.. its directly above the pos/neg inputs and says 2/8.

I also meant to say that the amp is a 2000. 4 not a 2000.2

ok, so that allows you to select the ohms, but how in the heck do i wire it up off of a 2000watt 4 channel amp and how do i set the switch?

what amp do you have? I doubt if it'll make that much power

surely someone can offer me some advice on a wiring scenario
