i was just wondering how hard it was to get up to 150? i'm asking because this guy on another site thinks he is just the car audio god ( and a real smartass) because he has 2 lvl 5 dc 15"s with a wall in his truck and this is what he said to another member the other day Quote {
quote:
its not cheap to get a 150, 90% of people will never hear one that loud, and 95% of people wont ever have a system that loud...its not cheap and its not easy, lots of hard work, hell the average person is a 130 if that, id say if anything your maybe a 135
another post quote{better be prepaired to fix lots of broken parts on your truck and spend some cash..im lucky enough to be real tight with some companies, but its not cheap to be doin a 150+ from 26hz-50hz}.


so can 150 be done with say 10"s or 12"s? im not trying to do a build with 150 but just curious.

i've done 152 with a single 10. not with music, all burps.

he is rite, it isnt easy to do, especially in a low frequency range. it's either very expensive (need lot of cone and power) or requires alot of work, testing and tuning (making maaaaaaaaany boxes).

just to give u an idea, in my 04 grand cherokee i was doing just over 150 with music and the system consisted of 3 DD 9512's and 2 DD Z1 amplifiers. Also had 2 hawker 2150 batteries and lots of wire. Total for that I would say is around $4,000, and thats rounding it off. I didnt have a wall, just a normal box in the trunk. For a wall add another $500-$700.

it is not cheap or easy!! but things are getting better than they used to be years ago!! IMO I don't think that he should be talking anyone down there are a lot of people that are doing well over a 150.9 DB and we all should be a little more humble@!! no matter who you are you can always be beaten!!

My wall of 4-15" did 55's @ 42hz and I was sad over that, I thought to myself that I might as well not even bother compete with that! lol

To do a 150 below 50hz on music for sure isn't easy for the average person. Pure spl box with higher frequency is easier but won't play music.

Last two vehicles I've worked on had at least $3000 in equipment to do 150db at 45hz or lower for music. And that's with our knowledge of knowing how to build a loud box.

well i started a budget build, consists of 4 18's that are bastardized RE sx's, a wall, orion 2500d.

its doing 153.0 db @ 38hz...the faces are taped in cuz im still in "testing" stages, i keep breaking things(port peices, face screws, and random screws) cuz i havnt used any glue other than for the outer shell.

this was my first attempt at a wall, im pretty happy with it, i cant seem to gain any more with the imperfections in the wall, so its gonne be marked, ripped out and re done with less restrictive parts and glue/fiberglass rather than tape...lol

so far i have like 1600-1700 in it with equipment, cheap thrill for now...only gets more expensive from here...lol

GL with ur build

back in 2001 they didn't have the new style of meters either. So that score was probably only a 143-145.

I can easily do over a 150 on music and consistantly bassrace 149.9's. It wasn't exactly easy getting there and took almost an entire year for the car to get there. I don't have a ton of money wrapped up in equiptment like some do, but part of it could be because I'm sponsored by Sundown Audio and that's what subs and amps I run in my car. I can't tell the cost of those products, but everything else is game so I've got around $1000 in everything but amps and subs.

Your leaving out alot of pertinent information.

You need to look at the type of vehicle your working with. And suv or small hatchback car will be alot easier to reach 150 db in then if your trying to do it with a trunk car.

It can be done in either application I would just plan differently for each.

IMHO reaching a 150db on music with a wall is not that difficult.

I managed a 150.3 @ 30hz with 8 10's and 2 Hifonics hercules (4000 watts). It was mostly luck for me.

I agree with you Fred when you say a 150 in a wall on music isn't that hard. Hell, I'd bet that on my first try I could build a wall with 2 12's and do a 150+ on music. My car is a no wall setup in a hatchback with a backseat, so it's not as easy as a car like a crx or a panda but easier than a trunk car.

Zach, your doing some nice numbers from the hatch of a Focus, and playing music with it is a +. I always thought those car had potential to get loud and glad to see someone is actually doing it. I am a bit biased towards loud daily drivers and have lots of respect for those that can break the 150 mark in the 30 hz range.

I believe the original poster was lead to believe that a 150 db is the holy end all of being loud and it doesn't get any better than that. What most don't realize is there is a huge difference between doing it at 60 hz and doing it at 30 hz.

i was just mainly curious as to others thoughts on this the guy that i quoted competes and has 2 dc lvl 5 15's on a 7kw amp with a ported wall in a newer model ford f150 screw. i have never done any of this measuring db levels and such so really have no idea how loud of a system would be around a 150. i have seen some of his videos that he's posted and think that my grand am i had with 4 12"s in the trunk would do about the same as what he showed on his videos with the hair tricks and such it would push the air out the windows to do that stuff.

I have done 153dB@44hz with 1500wrms(one battery too) in my vehicle. It was four 15's but I am sure 2 would be still over 150.

Get your vehicle, reinforce interior while keeping it stock looking. You can either wall it or not, both will do what you need it to do. Get 2kw power and a couple good 15's. Easy 150 at 30-50hz.

Playing up to a 150 is easy and can be done cheap even in a trunk car. Past a 150 it becomes a choice of money OR time. You can buy loud or build loud some get lucky and get it right on the 1st try others spend years getting every last 1/10 they can.

What I have seen,150 Burp in most any SUV or hatch back can be done for $500-800. 153-155 burp is the right hatch(cough crx) or a suv(cough explorer)is in the $1200-2000 range. I would execpt 20-50% more money to make the same vechiel be able to play music.

Trunk cars area diffrent type or beast. A trunk is not going to play high freq's and that will make it harder. To get a 150 burp in most trunk cars I would guess $1000-1500 in gear maybe $200-500 more to be able to play music that loud. To get a trunk car playing music well into the 150's would be doing something. I dont think a 1st time builder would be able to do this, experince would be a key factor.....or lots or money.

Walls....well lets not go there point being they get loud easyer then any of the other types or build listed.

To get your 150 the 1st thing you have to forget about is making it look good, that can come later. As for keeping it stock that depends on what you mean. Dynamate will almost have to be used but that dosnt realy affect the "stock look"

My sugestion would be lots of power and stong subs......and lots of MDF. I'm sure it can be done but unless you have to prove to your self it can be done it may not be worth it. I know a lot of people that spend every last dime and every waking minuite to reach there goal. I guess YOU need to decide if you just want to do it for the hell of it(or to make some 1 eat there words) or if you are wanting to push your self to the edge.


Link to said site and thread with smart a$$ ????? Depending on the context of the remarks the person ranting might need a realty check for some or the memebers here.

He speaks of this site like he knows of it but I dont rember seeing that screen name. Could be diffrent or maybe he has never been to this site.

To me the guy seems like he is just full of him self and gets off cutting people down. I realy dont think I would pay much attn to the guy. If he keeps talking smack just get his real name and look him up on here to see if he even has a stats page with real numbers.

Also looking at his profile eather he likes messing with people or he is real that young and just full of him self.

I would move on and stop letting the guy get to ya. Negitive comments like that do nothing to help new people grow this hobby.

he doesnt bother me im 30 years old and mature enough not to let it. but he seems to down talk alot of people on that site that are just starting to do there very first audio builds and such.i guess it just kinda aggravates me just a little when people think they are the **** and no one can be better or do better than them. but i was mainly just curious as to how hard it was to get a 150 since he said few people will ever have a system that loud. he real name is logan berry of (team nor*cal bass). says he competes in 149.9 bass race and phyclone
just how do you go about pulling up some ones stats on here i have seen it before but i just cant seem to find it again.

the truth is your average joe is not usually going to have a system that loud and that's what he's going to get at, you're not going to have someone who has no clue what they're doing pop a 150
