More runs of 0 gauge?
profundus-sanus replied to boxman420's topic in Electrical-battery- Alternators- Wiring
as stated with a 270xp you need AT LEAST 4 runs of 1/0(2+ and 2-) i would do 5 (3+ and 2-) plus those chassis grounds you already have. imo power wire is the most often skimped on piece of a build... -
you can attempt to simulate cabin gain by inserting the linkiwitz transform. i really only use bassbox pro for bandpasses though

yea man. thats exactly what it looks like. clipping light is lighting up when the voltage reaches a certain point. Since the deck was obviously clippin and the light was not conastantly lit*. no way it could actually be measuring any form of distortion. good stuff! at least jbl is trying haha. keep people from just runnning the gain maxxed out... although a -15db track is kinda on the sketchy side

yes!!!! can't wait for a dd1 I can actually use haha. oh damn, i wasn't sure what type of reception it would get but there should be a few that will love it. I will tell you what, the HV will be like $15.00 more but i will waive that fee if you buy one and make you the first to own one....just post a few pics and give an HONEST review. We are confident the review will be good so i say that with confidence. should be ready in about a week. thanks! yea man. An aq20 @ 15.5v input toasted our regular dd1. You actually have it for repair right now. I knew I was right at the limit so i was watching the output voltage like a hawk. I loved the thing man, so it'll be great having one i wont have to worry about when i'm firing up these ns-1's at 18.5volts.

Yeah looks like they'll be slapping around everywhere, stitching them to the spider yourself? actually they wont do much slapping, if anything, to me they seem stretched out and could use some slack. with 60mm of linear travel (30mm xmax) I think it could rip them and or cause slap. does it have the little cushions on the cone like some drivers do with leads like that? other than that its a very good looking driver, the crinkle coat looks good and the blacked out plates. Looks like zcon with a bigger bumped bottom plate. What's a rough guesstimate on weight? i will let the engineers at AA worry about if it is going to do damage or if it needs the little cushions. Oh, and sorry but the zcon looks like the Havoc not the other way around. damn man, drinkin that haterade its true, how is that hating? And whats your problem? Nevermind, don't answer that. I already know what it is....speaking of haterade. LOL the man just asked a question.... he asked if there were pads on there. and i just said i would let the engineers decide if they needed pads. I just got the f#ckin things, i dont have the answers yet. Are you done now? smh i seriously don't see what your getting upset about. the guy had a legit question about the woofers. Its kinda hard to tell if there are pads on the back of the cone or not.

HO Alt no ground?
profundus-sanus replied to Amart88's topic in Electrical-battery- Alternators- Wiring
So being a unibody car where the stock battery is in the trunk, would I benefit at all by running a run of 1/0 from a mounting bolt to the negitive battery terminal in trunk? Technically considering where your battery is located, thats part of your big 3 that you failed to do it sounds like. Do you have a ground going from the engine block to the battery in the rear? this. a ground from the alternator mounting bolt to the battery is/should be part of your big 3. no the alt should not have a ground stud on it. -
How to calculate amplifier amperage draw?
profundus-sanus replied to Chaosgrunt's topic in Amplifiers
1000 amps a piece? sounds like clipping to me haha. 3500/ 12.8= 273 amps 273 / .7 = 390 (after a less than optimistic efficiency estimate) 390x 4 = 1500 amps -
How to calculate amplifier amperage draw?
profundus-sanus replied to Chaosgrunt's topic in Amplifiers
its all a compromise. make sure you ahve a voltage gauge up front thats wired right before your amps. its a safe bet that your amps will be 70-75% efficient at 1 ohm full bore.. so with 4 amps your looking at 1500 amps draw. 2 300 amp alts bring you down to 900 amps draw.. which you'll need at least 7-8 group 31 batts you should have at least 2 + and 2- 1/0 runs per alt if your running 300a units. -
tuning eq after using dd-1
profundus-sanus replied to nosho47's topic in SMD Distortion Detector (DD-1) Topics
this is correct. if you use a dd1 you cannot boost anything in the signal without clipping -
