Cdizzle Posted May 4, 2007 Report Posted May 4, 2007 I was wondering why I have my dual 2 ohm Kicker Comp VR hooked up for a 4 ohm load, and it reads 5.3 ohms on the meter? Damn Thiefs
sean 371 Posted May 4, 2007 Report Posted May 4, 2007 It's called cabin gain. When it's placed in an enclosure and in a car, the resistance increases slightly. That's why a lot of high end sub manufacturers make there coils .7 and 1.4 ohms instead of 1 and 2. A couple links to some box builds: Tahoe Box 1, Tahoe Box 2, Nissan Titan, VW GTI, Mini-Bump, Hummer H2, Ford F-150 My own car builds (current setup --- under construction): Overall Thread, Kickpods, Dash, Back Doors Subwoofer Wall
ChevyBoy Posted May 4, 2007 Report Posted May 4, 2007 also, rarely is a coil exactly what it says in the first place. and its actually called box rise.
sean 371 Posted May 4, 2007 Report Posted May 4, 2007 Gah...youre right. Cabin gain is the apparent increase in enclosure tuning when a box is placed in a car.

ChevyBoy Posted May 4, 2007 Report Posted May 4, 2007 I thought it was impedence rise? same as box rise.
Slinky Posted May 4, 2007 Report Posted May 4, 2007 5.3 ohms is really fuckin high. did you take that reading with the amp turned off?

dleccord Posted May 4, 2007 Report Posted May 4, 2007 i bet you're using terminal cups or bolts. some of the resistance on those shit are stupid. refs: chode69, superduper
