And bill has I believe still does use them as midbassjust use a very small sealed box -
8" M2 question

They can fit You have to trim the edge and put a perfect layer if glue down -
In all fairness to this amplifier, I've never tested one so can't say for sure. Although, basic math would suggest it isn't possible. From their published data: 20kw @ 14.4V with 86% eff. = 20,000 / .86 = 23,255 watts input / 14.4V = 1615 Amps DC. / Three 0 AWG = 538A per 0 AWG. Maybe possible, sounds a little sketchy. But the devil is in the details. That efficency rating is at 4 ohms. At 1 ohm it will be around 65%. They don't mention that. Now doing the same math with real numbers we see that we would need 2136A at 14.4V. This isn't happening on 3 runs of 1/0. It gets better than that Zapco says its current consumption is only 600 amps Don't get me wrong but come on 600 amp draw and producing 14k

me too except the only problem is i have 8 amps on 8 coils and my wiring is all nice. I'm not pulling it all apart any time soon and even if i did, its just gonna give me an amp by amp reading. (nothing is strapped, not even a single pair of amps. They are all individual)anyway, i am planning on trying the AD-1 on all sorts of things. Like Tony said, moving the cap further away from the amp was enough to change the results. Also, forget Amplifiers, don't make me do a "wire shootout"....ill take tests @ 50 ft , 10 and maybe 18" or something like that and see what brand delivers the most power. Ill even toss welding cable in the mix. The Dyno isn't just about your amp making or not making power, lots of things can be a factor Don't make me do a battery battle too if you catch my drift....do they even make those pretty blue things anymore? That was kind of a of derp statement by me I guess. Didn't think about the multiple amp thing, clamping one at a time.So maybe then, A setup with alts and batts and a single big amp, like an AB1100 or something. I know lots of stuff factors in, just curious about the caps on a more powerful setup. Rays setup (dc98hoe) It's 2 amps but he has caps real caps (I beleive it's 2 banks of maxwells now) It would be interesting to see how much power he's clamping with and without them

call Scott, at ascendant, and tell him you would like steve to quit sandbagging. I could have put 40 RF woofers in the van by now but like everything, i wait, and wait, and wait.......even the spiders that moved in, moved out (cob webs).i guess its a work van until i get my woofers. Then i can start planning. think maybe a petition for them to hurry up could work? would also like to point out that they didnt move out because of it taking to long, they heard its gonna be your next big build and didnt want to get caught in the airflow. if he has a plan he is making us wait. if he doesnt i would say its because they are still doing testing on the subs he is gonna be using. Steve does the initial testing Ill let him tell u I asked a specific question... But what do I know ha

Lets guess c&d batts? Either way my point is still valid. The gas in idle time for the vehicles entire life will be less than half of ur batts..... Plus people saying ill hurt the batteries, probably not especially if u charge at nights (deep cycle batteries need to cycle full to empty or they will never work to their potential) that being said ur amps will smoke before u kill ur batts! Amps get warm when they have to work harder heat is ur biggest enemy, at lower voltages the amp will have to work harder, a lot harder! Thus becoming hot and then smoking etc... Just run ur car when u play ur stereo! It will save u $ in the long run

Nothing about mounting more than one alt is easy... I had a sure thing bracket been used a million times on cop cars everywhere.... still took me few hours and I'm pretty damn handy with wrenches... But good luck building your own props to you if it works out Might want to talk to cj18 on here he built his own but recently dropped back to 2 alts cuz 3 really loads ur engine down A high output lay draws 8hp ish at max production.... That being a said it strains ur engine..... Don't let anyone EVER tell u they don't, taking hp/ torque directly from the crank is the fastest way to loose hp!

It all comes down to port velocity..... Which is determined by port area and tuning frequency You need a specific number.... Also very important and a good quote from Hackmunch "Port flares Well enginering studies show that a 20% radius is optimal for spl and cutiing down turbulance to an absolute minimium. So a proper 8" flare should have a minimium of 1.6" radius . 8" + 3.2" =11.2 plus flat for mounting. Anyone making pvc flares (won't mention any names)with less than 20% radius is really wasting peoples time and money. Don't get me wrong a little flare is better than nothing but a proper flare is wayyy better than a little one."

I'm at 28 inches of port per cube with my 4th My buddy bill is right around 20 with a similar box to urs I would at least do 20 but that's just me 18 would work

Need more port imo Closer to 18 or 20 inches of port per cube

DC Level 6 question about FS
CortezDTV replied to the_garynator's topic in DC Sound Lab - Big Bass on ANOTHER LEVEL!
Wasn't trying to be rude before..... Also how a sub is broken in can change the specs from one sub to another One that is burped at break in vs one that is gently massaged for a few weeks or months etc etc In general the ya specs are close but look at it like amps they don't all clamp the exact same numbers but they are the "same" and have very similar numbers
