(4) Custom Fi 18's (4) AP30001Ds 45 cubic feet 20" port @ 24Hz

holding these just isn't the same as the IB3s and all the other subs I've done, so here's the break in rig I built for the cute little guys. Again thanks to zora, he has been an amazing seller all the way.

Im already getting lots of comments on the break in vids and I havent even posted them up yet, so I know when I do I'm going to get a lot more of this but: it is NOT bottoming out. I've been running subs free air full excursion as well as running subs full excursion loaded in enclosures for over 10 years. I generally know the difference between tinsel slap, air slapping the dustcap being forced through a pole vent, spiders pulling tight, rocking, scraping, bent coil, coil on bottom plate, cone on spider landing, surrounds pulling tight. I am no expert but I am no novice (despite loving to **** everyone off and doing things different, MY way not YOUR way //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif )

Anyway, yes the sub is very noisy and I haven't figured out what it is yet or whether it will be an issue loaded or not, but here they are //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

the EP4000 doesnt like a 2ohm load, even with just 1 sub free air //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif


 
Can an EP4000 be clipping without the clip indicating lights coming on? They are set to go on...Ive done it enough times with the IB3s to know, but maybe with it being at 2ohms it "doesn't know"? The sub is really out there in excursion before it gets too noisy, the amp gets warm, and the master volume is at -11dB which is 4dB louder than I ever have it and 14dB louder than I usually have it. Master volume being that high with 1/2 the impedance has me wondering, though even if I bring it to -9dB and it really gets loud, the clip lights still dont even tickle.

 
Hope youve got a big electrical
Flare the port to make it pretty

I love it

I don't! I could only afford three AGMs, two are 100aH each, and I have an Iraggi 220A alt and an Excessive Amperage 300A but I can't get brackets to add the 300A //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

If I can get 2 brackets to mount the 300A then yeah, I'll have the electrical //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I can't flare the port //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif I want to so bad, but I only have 1/2" between the port and subwoofer cut outs... when the subs are in and mounted, they are right up against the port!
