right now i have it set up like picture 2 . one inverted and the other is normal. they are type X tho. these are type R's back in the day lol....

i was gotta add 2 more 90* on top of the ones i got going on and have lengh of tube added to 4 of them, approx 25"...

Do you have one of the subs wired out of phase? Meaning 1 normal and 1 with the pos & neg reversed. If both are normal or both inverted then it doesnt matter but one each way it does

01 Chevy Silverado X-cab

2 Sundown Z18v4 walled on 2 Lanzar Opti 7k's strapped at 1/2ohm = each amp wired to 1/4ohm. Havent checked impedence rise so not sure what they are actually seeing. 6 group 31AGM's.

2-Eclipse 34230's each one running 2 Eminence 6.5" Beta 6A. These are beastly mids rated at 350w program power. I was skeptical but the eclipse amps are 370w x 2 and when there was 4 mids on 1 amp I could push it into thermal protect within a song so added the 2nd amp. 

Eclipse 4212 running 4 CT sounds Meso tweeters. and 2 DLS ultimate tweeters up high to raise the soundstage.

 

96' Ford F350 4wd 4d long bed 7.3 diesel with 91k miles. Will be the sound quality rig if I can ever find the time.

Yes one sub is reverse polarity. Like its loud now after setting the gains with oscilloscope. But would it be louder with more port area
