a_steezy Posted December 23, 2008 Report Posted December 23, 2008 i know it's a stupid question ha but i think i blew 1 of the two coils on my L7 i the sub is wired to 2 ohms and has been, checked it this morning and it said it was at +-1.4 ohms, i've checked it in the past and it's always said 2.0 is there a way to check each individual coil or where should i go from here?

AI James Posted December 23, 2008 Report Posted December 23, 2008 measure resistance of each one Quote
a_steezy Posted December 23, 2008 Author Report Posted December 23, 2008 measure resistance of each one oh damn haha gotcha, i think i was putting it from +vc1 into +vc2 not staying in the same vc+ to - hardcore brainfart, thanks james Quote '98 Dodge Durango 5.9L 5% front windows, 2.5% on all backs Alpine CDA-9883 Kicker ZX350.4 Kicker KS650's in all doors Kicker 1/0 hyperflex
a_steezy Posted December 23, 2008 Author Report Posted December 23, 2008 final ohm load on the sub this morning was 1.4ish vc1= 3.0 ohm vc2= 3.6 ohm it's a 4 ohm sub... what is this telling me? i'm lost Quote '98 Dodge Durango 5.9L 5% front windows, 2.5% on all backs Alpine CDA-9883 Kicker ZX350.4 Kicker KS650's in all doors Kicker 1/0 hyperflex
a_steezy Posted December 23, 2008 Author Report Posted December 23, 2008 my L7 it's a 4 ohm dvc sub... always had it wired to 2 ohms last night amp started cutting out zx1500.1 and i believe it's because the final ohm load on the sub this morning was 1.4ish and the amp would handle it...? just checked each vc vc1= 3.0 ohm vc2= 3.6 ohm what is this telling me? i'm lost remember it's a 4 ohm sub and i'm getting 3's Quote '98 Dodge Durango 5.9L 5% front windows, 2.5% on all backs Alpine CDA-9883 Kicker ZX350.4 Kicker KS650's in all doors Kicker 1/0 hyperflex
reinke Posted December 23, 2008 Report Posted December 23, 2008 i wouldnt think anything is wrong if it is playing fine. you probably broke it in finally. Quote ----reference's---- meade916
Guest Posted December 23, 2008 Report Posted December 23, 2008 3 and 3.6 are good numbers for a dual 4 ohm coil, with box impedance rise you should be just around 2 ohms (with the way you have it wired already). check your RCA's, power, ground, speaker wire, any wire shorts. btw whats up with your avatar steezy lol, i keep staring at it Quote

banginAltima Posted December 23, 2008 Report Posted December 23, 2008 Touching the cone in any way will change the ohms. Moving the sub while trying to get a reading will change it also. If the sub is loose enough, even wind can change the reading. Quote If you build it, db's will come... NSPL World Record Holder Trunk 0-1800 watts---147.9 with 1722 clamped watts @ 40Hz(9-20-09).

Boon Posted December 23, 2008 Report Posted December 23, 2008 Wow whoever is saying it's fine is rather totally wrong (Krannyman, reinke...) The coils should be almost the same impedance. Clearly you have burnt the coil that's at 3 ohms and some of the windings are shorting together. Stop using the sub. It's fucked. Quote 10.x volts fo' life!
