Hey guys, i'm new here, and not really sure what it's called but here's the thing i'm looking for, if you have links to cheaper ones or one used let me know. I want to be able to control the sub level because my amp (Alpine MRP-M500) doesn't come with a knob. Thanks. here's an example of what i'm looking for.

BUMP/EDIT http://cgi.ebay.com/ebaymotors/NEW-...udio_Video&hash=item53e4c4de4e#ht_1849wt_1165 I found that, i'm just looking for a knob to easily shut off/turn on or turn up or down my sub, i currently have a alpine type-r powered by the mrp-m500, will this work and has anyone used it? thanks!
