hzsogood Posted December 22, 2012 Report Posted December 22, 2012 Just hot the subs in my new car but only problem is they sound like shit. Hollow and quiet. And it's from the same setup I had before nothing was changed. So I checked each vc terminal with a dmm and one coil was all over the place and would hold on any particular number. What should each coil read when not wired , and or wired in parallel ? Subs are 08-09 model lvl 3 12s. Quote
hzsogood Posted December 22, 2012 Author Report Posted December 22, 2012 Also it seems to sound worse the more I turn it up. I set the gains with a dmm and as far as I can see everything on the HU is good to go. HU - jvc kw60bt ( brand new ) Amp- audioque 1200d ( brand new ) Quote
CJ18 Posted December 22, 2012 Report Posted December 22, 2012 read each coil separately. If one jumps around, then it is blown Quote
hzsogood Posted December 22, 2012 Author Report Posted December 22, 2012 read each coil separately. If one jumps around, then it is blown Thanks man. Yea they were all right around the same impedance except for the one which was bounding all over. What SHOULD they all read separately, with no jumpers on? And I noticed when I wiggled the tinsel lead it stayed on a number... It's really weird Quote
hzsogood Posted December 22, 2012 Author Report Posted December 22, 2012 Under the hood reads 13.86 volts. As well as at the amp. The remote/ground on the amp reads 13.35. Is that low? Quote
will77530 Posted December 22, 2012 Report Posted December 22, 2012 they could read around 2 ohm or 4 ohm depends on what coils you have my guess is around 4 ohms sense you have two Quote
hzsogood Posted December 22, 2012 Author Report Posted December 22, 2012 they could read around 2 ohm or 4 ohm depends on what coils you have my guess is around 4 ohms sense you have two Yep. I have dual 4 ohm coils. Just didn't know if it was supposed to be dead on. One was 3.6 one was 3.9 another was 3.2 then the wild one that was all over. It still plays but just sounds like crap , like I said especially when you turn it up Quote
ChevyBoy95 Posted December 22, 2012 Report Posted December 22, 2012 Make sure they dont have reversed polarities. Sounds like they could be canceling each other.

CJ18 Posted December 22, 2012 Report Posted December 22, 2012 Dont worry about anything else said here. Your question is do you have a blown coil. Take your dmm and set to ohms. Check each coil separately. If they dont match, and 1 is jumping all over the place, then you have a blown coil and need a recone. Quote
