A sealed box is great, but you need DOUBLE the watts to get the same output of a ported box. A ported box is the best for big bass, as long as you buy a great/clean big amp and use a cap. Bandpass boxes are awesome, but require perfect design/build. I have built about 20 subs using Bassbox 6.0 and proper designs. Some subs require a sealed box, while others require a ported box. I suggest JL Audio W-7 woofers/ported.

 

LMFAO another believe the hip bass head........

very typical..... ROCK NOTHING BUT JLaudio AND MUST USE A CAP..... LMFAO

caps dont help ANYTHING!!!!! if anything they hurt your system more than they help! be a real man and either upgrade the alternator to a high output alternator OR buy more batteries! use something that either MAKES POWER OR STORES POWER!

not trying to be an @ss or anything even tho im sure it sounds like it
but its all well know fact CAPS dont help anything...... dont believe me????????? go to the next stereo competition where the loudest of DB competitors are and check out their systems!!!!!! you wont find a ONE CAPACITOR! youll see highoutput alternators and MULTIPLE batteries.....

BUT if you wanna waste money on a cap still..... go ahead its just a waste/paperweight......

 

You know, if I was not so lazy I could honestly pick apart damn near every post in this thread and point out a number of flaws in everyones statements. Like I said I'm lazy, so maybe later.

 

well... is it later yet? lol Capacitors do help (the life of your battery and amp) if your amp cannot pull sufficient ower from your alternator/batteries at a given moment, but if you are going to play them loud for a long time, do what addiction said, upgrade your alternater and batteries, because that will be your best bet.

 

ya but capacitors dont make or store that much power.... i could fart longer than a capacitor can hold a charge.... it takes 2-3seconds to charge a decent size 1farad cap.... with a test light.... and can you realy say that that LITTLE ammount of power can help anything?

a highoutput alternator is your best option! lets face it hondas got THE CRAPPIEST BABY 70amp alternator STOCK... and a BABY BATTERY with very little CCA and reserve power..... if you upgrade the alternator and the battery or even a second battery in the trunk that will help ATON MORE than some little capacitor could ever!

upgrade right the first time and forget about it! otherwise ya just wasted 100bucks for a capacitor... when that 100bucks coulda gone into a new battery.... or half of a highpower alternator...

 

WOW. Have been to sound offs and also have many friends with systems that MOVE pavement. NONE of them have huge batts or alternators. Just a big cap or 2. Caps DO WORK. I remember 20 years ago when caps didn't exist, and many had big batts and alternators. Nothing like the bass in cars today. Think what you want, I don't really care. If you don't want to mess around with expensive batteries and alternators, just get a good amp and a cap. Enough said.

 

SHOW ME THEN........... cause im calling out ALL BS!!!!!!!!!!
look at REAL COMPETITION VEHICLES!!!!!!!!! ALL BATTERIES>>>>> MULTIPLE HIGHPOWER ALTERNATORS.... and not even a 0.5farad cap in site!!!!!!
its for a reason... TO MAKE POWER YOU NEED POWER! do you realy thing a capacitor makes power?
do more research! and proce your point! i can point you in any true competitors corner and you can see yourself... but when yoru young ANY system sounds like its PAVEMENT POUNDING!!!!!!! LOL

FIND ME A SYSTEM THAT CAN DO THAT AND DOESNT USE multiple batteries or highpower alternators! TRUST ME YOUR NOT GOING TO FIND ANY!!!
do your research MEADE is DEFINATLY a EXTREMLY COMPETITIVE BUILDER! and does SOME NICE SICK WORK!


including his SUPER SICK CIVIC!

 

A cap discharges far to quickly to do anything, larger subs do not have a lower xmax all the time and even when they do it does not matter as it is all about moving air. A single 15 inch sub will diplace as much air as 2 12 inch subs of the same make/level. Ported boxes are far more effeiciant than any other type of box, a "ABC" box generally has a wider range of freq that it will play at a higher level but is a little more peaky than a sealed box. A bandpass is a sloppy *** high bass note wonder, the bl curve with even a well designed bandpass is very peaky and the peak more times than not occures above 45hz.

Amps do not supply clean or dirty signal, I dont care how cheap. Now cheaper ones do not do what they say they will as far as power and on a whole even most that work at audio shops do not know how to properly tune a amp. The only 2 specs on a amp as far as dead set features that need to have attention payed to them other than the RMS rating is the dampening factor and the signal to noise ratio. Class d amps for the most part are low dampening amps with alower signal to noise ratio. They are in a sense a efficiant power supply that does not generate as much heat as a class a/b amp but they are also alot less precise amps as far as filtering noise out of your system. The only clas d amps I know of on the market as far as mass produced, easily found and bought status are JL Audio amps which have fixed power supplies and do not fluctuate the power given on different ohm loads.

Hifonics has good amps for the money and with that amount of power it depends on what you want to spend on a sub. Those amps make their power at 1ohm so you need a dual 2 ohm sub. I think you need to take a look at re audio and look at the RE MX 12 as it will take the power and only needs 1.5 to 2cu ft ported and get it tuned to 28 to 32hz. It will hit hard, last long, get low, and be a great sub.

 

Very nice diagram. Must be crack dealers with gold teeth and crooked baseball caps.

 

that just shows your foolishness!!!!!! meade is a very nice guy thats a hard worker! more of a workaholic id say cause after he does his DAILY JOB work... he comes home to building up some sweet @ss vehicles in his spare time!
check out his web site!

if you was anybody youd know that meade does the sweetest system instals!!!!!
dont be mad that your a JL freak and love caps......
if you wanna waste money then go right ahead. but i hate it when people say that JL is the ONLY good system equipment out thier and you need a capacitor.... dont get me wrong the HIGH MODEL of JL equipment is nice... but also OVERPRICED for the typical basshead. but no capacitor in the world can replace a highpower alternator and more batteries! only thing CLOSE to a capacitor that ive heard actualy working decent in combination with a highpower alternator is some BATCAPS. tho ive never personaly used one of them thats just what ive heard is they work preaty good mainly thier battery/cap pieces in one unit... but ill still stick to my YOU NEED POWER TO MAKE POWER...... alternators MAKE POWER for batteries to HOLD the power. whats a cap do. pisses on a forest fire..... doesnt effect anything to realy help! may look like it helps but FAR from geting the job done!
think about it... if the amp PULLS juice from the cap... whats the cap gotta do next?????? anyone got the answer.....? its just been drained....... ok ya give up it has to recharge!!!!! so while its RECHARGING its STARVING the amplifier of power... which inturn gives you the ILLUSION that its keeping your voltage up and lights from dimming but realy its just keeping the voltage down alittle so the lights dont seem to be FULLY LITE and then dimmed...

just go to your next local LARGE SPL comp and ask the BIG BOY BASSHEADS why they dont use a trunk full of capacitors instead of batteries..... tho ya might get laughed at....
