imadreamer1226 Posted May 12, 2010 Report Posted May 12, 2010 Picture speaks for itself. So if I am doing this test right, which I hope I am ... Im guessing I purchased the 2 ohm subs? Seller was unsure of what they were, and either way they were a good deal. Any input? I tested all 4 connections on the 2 subs, and the all are within .1 of each other, with 2.5 being the median.
97SSBlazer Posted May 12, 2010 Report Posted May 12, 2010 yea your doing it right. You dont have to clamp the basket. SUBS very RARELY read a perfect 4 or 4 ohms. As long as its close than your fine... lower tuning is just hard. I was surprised how loud 145 sounds at 35hz, and how quiet 145 sounds at 50hz. -= 2005 Tahoe LT =-Head unit: Pioneer AVH-X5500BHSSource: iPad Mini in dash Subs: 2 T1 12's Sub Amp: T1500-1bdCPWire: Rockford Fosgate 1/0 awgSignal Cable: MonsterFronts:Stock Bose for now:)Rears: Stock Bose for now:)MIds/High amp: Stock Bose for now:) 2005 Tahoe Build Log: http://www.stevemeadedesigns.com/board/topic/172529-2005-tahoe-my-17th-vehicle/ 2001 Monte Build Log: http://www.stevemeadedesigns.com/board/topic/160030-2001-monte-carlo-my-16th-car-lol/page-2#entry25309381997 Tahoe Build Log: http://www.stevemead...oe-6-15-rf-15s/2001 Impala Build Log: http://www.stevemead...katzkin-inside/

kmalinich Posted May 12, 2010 Report Posted May 12, 2010 yeah... 2.5 is kinda low for a 4 ohm coil.. too high for a 2 ohm coil...... but with box rise and all that you'll be A-OK
Boon Posted May 13, 2010 Report Posted May 13, 2010 Touch the leads together and hold it for like 30 seconds to let the number settle. You'll end up with some tiny number like 0.7, 0.9 maybe... unless you have a badass multimeter. This is the calibration error of your multimeter plus the resistance of the probes and wires. Subtract it from the reading you get off the coil. I dare say your leads + error will be about 0.7-0.8 ohms, giving you a coil DCR of ~1.7 which is normal for a '2 ohm' coil. 10.x volts fo' life!

I had a yellow craftsman DMM and when I did that it read a dead short.... does that mean i'm badass? the DMM was pretty sweet, it could measure just about anything. even temp probes and such. my dad ran it over with his suburban a few days ago though =/
