Aj11 Posted February 23, 2014 Report Posted February 23, 2014 your right! my system wasnt even a Lil loud! and I'm sure if they werent in.a shared space box it would have been more noticeable jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out)
Krakin Posted February 23, 2014 Report Posted February 23, 2014 Thank god you pulled out the book, I was just about to do all that math myself... Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.
33hz Posted February 23, 2014 Report Posted February 23, 2014 I forgot to mention but you should be seeing 1.6Ohms Basshead not audiophile
truthsayer Posted February 23, 2014 Report Posted February 23, 2014 i have 2 dvc 4ohm subs inverted so changing the resistance is waseasy for me. if you guys tell me what to do I'll run out change the wiring And make a video. i know your talking about dual 2ohm but you should still see the affect. i know my amp can take .5ohm so no worries on the low end. i can make a short video Oh ok you have dvc4 subs, I misread it. But yeah the same method applies and you'll see 0.6Ohms. It's easy enough to wire it up, you'll only need to change one sub. As for how to do it... That's a little hard explain in text so just look up a sub wiring diagram series vs parallel and do one of each Here you go. You like the fancy diagram program I used? LOL Actualy if you have two dvc 4 ohm subs, and you wire one sub parallel to get a 2ohm and the other sub in series to get a 8ohm load. Then you wire both in parallel to the amp. You will see a final 1.6ohm load. It;s the same as having a single 2ohm sub and a single 8ohm sub, wired in parallel for a 1.6ohm load. Without going through all the math calculations, just go to 12volt.com to simplify it. truthsayer
Aj11 Posted February 23, 2014 Report Posted February 23, 2014 yea it was 1.6 at the amp. i wish i had a box with separate air space, i think it would look much different. i knew there was gonna be a difference but my system was so much lower in volume it was like i had a single ten in a sealed box instead of 12s in a 6ft box jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out)
33hz Posted February 23, 2014 Report Posted February 23, 2014 ^Ha I noticed I got it wrong and thought I edited it before anyone noticed... I guess I thought wrong haha Basshead not audiophile

It shouldn't have been quieter Basshead not audiophile
Rail Posted February 23, 2014 Report Posted February 23, 2014 Formulas guys... Its simple stuff, no need for 12volt.com 4 and 4 parallel = (4-1 + 4-1)-1 = 2 ohms 4 and 4 series = 4 + 4 = 8 ohms Then take the two of them 2 and 8 parallel = (2-1 + 8-1)-1 = 1.6 ohms And also I don't doubt that it was a lot quieter, there is likely phase issues coming from different levels of excursion Chevrolet Tahoe Crescendo PWX6 (2) and FT1 (2) Fi Audio SP4 15" (1), AQ3500D.1 (1) Enclosure: 4th Order (Ported) 4.5cu ft @26Hz Mechman Elite 370A & Kinetik HC2000 Sky High 2/0 Wire Future Plans: (2) 18" @25Hz
33hz Posted February 23, 2014 Report Posted February 23, 2014 My experience was going from 2 8Ohms subs to 1 4Ohm + 1 8Ohm and it was a lot louder @ 2.7Ohms vs 4Ohms Edit: dual chambers though Basshead not audiophile
truthsayer Posted February 23, 2014 Report Posted February 23, 2014 ^Ha I noticed I got it wrong and thought I edited it before anyone noticed... I guess I thought wrong haha No problem, and my son is here and is giving me flack for not giving the simple answer the way i tought him. Simply put. series connections you just add the values together. Parallel- example 2ohm and 8ohm. 2x8=16, then 2+8=10. So take 16/10=1.6 final ohm load. Maybe that will help to make it easy for some. It's the simplest way i know how to explain it. truthsayer
