Unless it's Tri-capable which we know it's not. But questions like these shouldnt even be made.. The question is if the 8" sub is causing a loss of power to the 12" sub... Well, there is one simple test.. UNHOOK the 8 and find out.. What if we said no.. Then you'd never unhook it and be left confused til eternity. For every action, there is an equal and opposite reaction. hook up another speaker!!!! get less bass

there are competitors who use them in the lanes too.. People just like to use this as their base- They don't put out a clean signal at their rated power output. Well.. if they do or not, i don't know, i am not here to measure the specifics but like others, know of people who run them without problems... Hell, i even remember one time, lol, we took an ap3001d(stable at 2ohm) and wired it down to 0.45ohms to try and burp it.. We tried 4 different burp sessions. At full tilt rolling volume, all 4 times went into protect. We got a schematic which showed protect circuit kicked in at 1.32ohms and lower. And we clamped it dirty and was pleased with it's power to ohm ratio as well. If i could have ran 16 AP amps in my car i would have.. but no room, lol.

there's a difference between not having port noise and not hearing it. I've ran 4 15s before in a wall with only 144sqin of port tuned at 29hz on 14,000w worth of amps. I never heard any issues. I then rebuilt using 3 15s on 21,000w worth of amps using 265sqin of port tuned to ~36hz and still sounded fine. My new build in progress is 4 18s on ~310sqin of port on 22,000w (0.5ohms) I highly doubt i'll have any audible problems again.... speaker wise, not my ears.. oh no.. hehe.

i believe anything over $300 is a felony.. or is it right at $300?

How long can you wait. This holiday season is shaping up to be good with all kinds of possibilities. I can wait Make sure whatever phone you do get supports LTE. Many providers are finally starting to transition over to that new 4G and no current 4G phone by itself can accept LTE unless it specifically says it can.

It would have to be built inside the trunk firing forward, but it's possible.

i got 3 piezo sirens inside and they aren't all that loud. Just use external siren(s) inside.

sounds like you're driving the signal too high.

4.5cuft is too small to get low end out of it. Now, if it were like 6-7cuft tuned to 40hz, it would get deeper but obviously if you were to rebuild, you'd have control over tuning as well.

Hey guys, i've been talkin to Chicagofan for a while and decided to share with all the IAK some information to help you guys get LOUD LOUD! Do NOT distribute the following document to anybody outside of your team as you don't want your opponents to walk all over you. Knowledge is power! Don't forget that. Here is a link to a Word Document. Read it again and again and call me if you have any questions. I wish you all the best in getting louder as the season continues. Sensitive Competitor Design Info - Re-encrypted This document is encrypted and requires authentication to be read. I will be texting you Porkchop later this week with the authentication to unlock it. Do NOT give it out to anybody outside of IAK. Anybody else in IAK that doesn't have it, text me for it or pm me for my number. Again , I wish you all the best and good luck!

Its official I am not back in the game. I will make finals and the system, trying like HELL!

Haha... he's in X1 in MECA and only did a 121.8.. People can break over 160s in that class.

When doing just burping, make sure that trial and error tuning gets you the correct tuning. that's primary! IF you can ensure that you can always achieve the best tuning, then use the largest port area you can. I believe Gary Fletcher was using in excess of over 600sqin of port for just 2 18s in ~20cuft net on 2 sundown-1500s. He achieved a 159.4db

Alan dante.... I'm mobile so can't elaborate on everything We are getting to techy for this thread but comp, daily, etc has bearing on A common comparison when looked at.... averaging. Cone area and enclosure are both crucial. However, sacrificing one will require more power to compensate. The application is the factor in determining that.

For everyone that reads this... A STOCK alt is more durable than a HO alt. I'm mobile and can't explain why right now but think about Heat dissipation

Stop being technical... What about resistance in terminal? Did u perfectly crimp it? Heat inside engine bay lowers current flow of wire. What about resistance in material u are connecting terminals too?

Might wanna find out why the alt died now.

The long run cables to the rear is to help keep the voltage up for your alternator. If that ground cable you have ran from rear to front attaches to your front battery, then it would be wise of you to run an extra power AND ground cable from the alt to the front battery. The front battery itself doesn't need an extra ground on it. This will help keep the voltage high from the alt to the front battery since your rear battery has been decided to attach to the front battery.

Reality says otherwise. It's a well known fact that in competition, if you are burping, you use the LEAST cone area and if you are doing demosor averaging musical runs, you use the MOST cone area. Now why is that? Well, for averaging, more cone area equals better heat dissipation which means louder longer on AVERAGE. For burping, least cone area is required because the more cone you install, the more complex the output will be. Cancellation will be a problem, time alignment will be a problem. And the last thing, space. It's easier to fit less cone area than more. This allows for a more optimal or should i say EFFICIENT enclosure. So, what's more efficient, the enclosure or the cone area?

Yea.. sadly the videos are showing what these subs do at rest, lol.. pretty much. Get some 16hz or whatever it takes to get some movement on those bad boys. Unlike other new companies.. there will be something interesting with this one.

If you really want to get technical experience, you can purchase an SPL-Lab's meter and sit there and watchmeter what you are doing in the vehicle. This will better help you see what's happening than just reading about it because in the real world, there are many uncovered variables at play that's not talked about in this thread and probably will never be because it's too much to cover. Many people that do not compete own pressure meters for this very reason. They eventually get their daily setups louder without buying extra equipment. Positioning, box tuning, vehicle environment mods, etc will all effect pressure and when it starts to become audible that what you are seeing is having a great effect on your ears, you will then gain a large understanding and like others out there, maybe even start competing.

it's bester right now... In a few yrs, it will be bestest.

oh.. well to give u an example, i am reusing a bunch of my wire for this build from years ago of previous builds.. Some wire has had E-tape on it for years and those wires, only the tips of them had the tape coming loose but only because dirt got under it and lost it's adhesive. I doubt i'll have problems with it. that thermal insulation does make a difference. wish you could just stick your hand down there and feel the difference.

how about sealed at the headrest on classical music?
