Well, it seems like you kind of contradicted yourself. You're talking about how ported is better for SPL hands down, then you say you own an SPL record with a sealed enclosure setup. The fact that it was 4 15"s proves the FACT that it is about total cone surface area-which equates to the amount of air the speakers can displace (which is of course what SPL is).

But oh man, no offense, but since you put it out there. checked out your cardomain page. Dude that Geo is about the saddest thing on 4 wheels i've ever seen. Talk about a rice job! The enclosure doesn't look to be anything sophisticated at all... just a big ole box with 4 subs dropped in it stuffed in the back of a Geo tracker.

The silverado doesn't look like anything special at all. I mean the mtx's are nice, but other than that....its just a truck.

So you have 13 hours left in your "speaker break in process".... you feel like you're hitting around 143 dbs....and you have the amp "1/3 of the way up...????

 

You guys have me lost.... whats wrong with my speakers?

 

[quote="2LoTc"]lol lets see where to start. the geo holds state record , yes with a sealed box, in m3 class. for people who dont know its hatch modified with no back seat, so in this state since that competition no one has beat it. it was only 143.6 being pushed by an 800 watt amp. in order to get a ported to beat that it would need at least 3 15's in a ported box, and would be a friggin huge huge box. how many cars have the space for a ported box for 3 15's? not many. so total cone area is not the deciding factor.

i find it funny that you say the geo is the saddest thing on 4 wheels. that car has been places and gotten recognition that you could only dream about. i admit, i riced it up a little bit, but i was a kid when i did it. as far as big ol' box with speakers dropped in,not quite. speakerboxes take more then slapping wood together and putting speakers in, so good try on that one.

now for the silverado. the paint job alone on that truck cost more then your downpayment, along with the suspension. and to make a comment like the mtx's are nice, you definitely dont know wtf your talking about. there is many more things that stand out in the silverado that would take recognition before the subs, like the 2 bd1500's sitting at the top. or maybe the custom painted 383 sitting under the hood, or shaved all around with fbss, but then again maybe i know nothing about customs.

so yes, im sitting at 1/3 power, roughly 13hours left for break in. read on spl levels and how to achieve them. anything past 143/144 db is an extreme increase, not found by 100 or 200 watts, but 300 to 400 watts increase.

 

Heres the rules, you do the math.


2006 Modifi ed Division Rules
MODIFIED - Intended for competitors with vehicles that have non-permanent modifi cations behind the B-pillars and are
designed to maximize sound pressure level, including woofer walls, but are still capable of being daily drivers.
5 Modifi ed Division “Pressure Classes”
M1 0 - 500
M2 501 - 750
M3 751 - 1200
M4 1201 - 2000
M5 2001 - 4000
A. Vehicle/Owner Requirements
1. If the owner/member or support team member chooses to sit in the vehicle during the pass, then they must sit in one of the front seats.
In addition, they may not sit on the same side of the vehicle where the sensor is placed.
2. , Brackets, panels and non-structural supports behind the B-pillars that can be unbolted or unscrewed can be removed, provided they can
be reinstalled using factory fasteners.
B. Judging Criteria
1. Any combination of open doors, windows, trunks, and hatches allowed. Hood must be closed completely during pass.
2. Peak frequency must not be above 100hz, as verifi ed by TermLab system.
C. Sensor Placement



1. In addition to the General Rules, sensor may be placed either on the driver or passenger side under the plane of the bottom of the dashboard.
D. System Requirements
1. No modifi cations to the front of the vehicle with the intent to increase sound pressure level score, except for the limited modifi cations
outlined in D.2 through D.9.
2. Enclosure cannot extend past any part of the front door jambs, except in a standard cab truck where it must fi t with the driver’s seat in
the most forward position.
3. Door panels may only be modifi ed and/or rebuilt to accommodate front stage speakers. Rebuilds are limited to the area required for
mounting of said speakers and must be fi nished and/or upholstered. Raw metal, wood, or fi berglass build-outs commonly used to increase
sound pressure level are prohibited.
4. OEM headliner or functional equivalent must be in vehicle and may be reupholstered, but not built with fi berglass or any other hard rigid
material. Headliners must be able to be removed, if necessary, to verify sound deadening on the roof of the vehicle.
5 Dash modifi cations are limited to mounting of; automotive gauges (i.e., tach or voltage gauge), for video system components (i.e., screen(s),
DVD player, game console), relocation of source unit, and/or mounting front stage speakers for SQL applications.
6. Dash may only be recovered with a cloth type material. Painting to match a color scheme of the vehicle will also be allowed.
7. Only rubberized/asphalt type sound deadening material is allowed to be used in front the B-pillars, 2 layers maximum in any area.
Spray foam, resins, duct tape, or any similar materials used to increase sound pressure score are prohibited in front of the B-pillars.
8. Vehicle must have automotive seats properly mounted in the forward only position. Neither the front driver’s nor front passenger’s seats
can be removed. Racing seats or any type of DOT approved automotive seat may be used: no homemade, marine, or other types allowed.
9. Center consoles may be removed or rebuilt as long as the design does not intentionally redirect pressure which may increase sound pressure
score.
10. Podiums are permitted.
11. Upgraded electrical and charging system allowed, however, vehicle is restricted to a maximum of two (2) alternators.
12. Capacitors are allowed. Capacitance limit is 50 Farads total.
13. In addition to the vehicle’s primary battery, M1 is permitted one (1) extra battery. M2 may have two (2) extra batteries, M3 may have
three (3) extra batteries, M4 may have four (4) extra batteries. and M5 may have fi ve (5) extra batteries.
14. 12 volt batteries only, in parallel, are permitted. Group 8D batteries and the NSB-90 are counted as two (2) batteries, Xstatic Model
8400’s and EaglePicher’s are counted as three (3) batteries.
15. Primary battery may be relocated. All batteries must be securely mounted, and must be located either under the hood and/or be mounted
anywhere behind the B-pillars, with-in the original skin of the vehicle.
- Some unique situations may arise that disqualify vehicle, system, and/or competitor from Modifi ed Division, determined by
MECA Judges.

btw sorry teecee didnt mean to jack up your thread, but for the record,here is my "JUST A TRUCK"

 

Hick trucks. not impressed at all. and i can appreciate GOOD custom work. sorry, bro..you don't got it. WAAAAYYY off topic.

I say lock this.

 

you have got to be kidding me? where the **** are you from where hicks drive trucks like that? man what kind of ghetto is that. second off ive never seen a hick slam a truck on the ground. done replying to your ignorance.

 

haha! definitely NO trucks like THAT in philly...or even the suburbs...you'd have to go out to mid or western PA (or Virginia) to find a monstrosity like that sad piece.

Dude, the silverado aside...The GEO is a ricy chick car. DON'T be proud of EITHER of those rides. HOpefully you have better taste with the tc.

wanna see some "bad" trucks.. www.blazinlow.com MY boys site w/ his "tasteful" trucks and others... Take some notes.

 

Back to what i was saying , i will not feed your ignorance.

 

lol your right that blazinlow site is way funnier than his flame trucks of doom



better than all those other ricer sites thanks 2LoT

Notes:

get custom flames
done

 

lol i wasnt gonna look at the site but now youve intrigued me. there are some nice blazers on there, but alot of stock ones with rims. but now i see where you get the redneck truck idea, man they'res alot of redneck trucks on that their page, i can see them sloshing through the mud right now ya hear, BERTHA , GET THE SHEEP..

 

Nothing wrong with your sub system, don't worry, they're just arguing about potential SPL and the best way to acheive it. If you're not going to compete in SPL contests and your system sounds good to you, nothing else really matters

Also, saw your post about painting the edges of the plexi black to make it look better. Another option would be to "edge light" the plexi with a cold cathode neon tube or LEDs using the color of your choice, which would look much better than painted edges.

 

I'm not arguing. that last pollup post was WAAYYY off topic.

You just took MEMBER pictures from my friends site of over 100 members who PAY HIM MONEY to be a member of his site because HIS 2 BlAZers (which you mysteriously neglected to post in this Scion forum) are sick. way better than your Hickerado and Geo Ricer. Go post some pics of the white blazer somewhere. if you're into trucks, you probably went to Carlisle once in the last 5 years and saw it there...

 

Wow... lets keep the ____ing contests to pm's please. Totally jacking this dudes thread. Anyway.... dude I REALLY like that box how much did you throw down for it, custom job im sure.

 

i didnt post the blazer photo in the first place, another member posted it, i laughed at it, along with many others who viewed that "BLAZIN LOW BLAZER". But back on topic.

Your box looks sick, i agree with the painting the edges or edge lighting , it will look sick.

 

you're right... "in the first place, you posted pics of your Geo Tracker ( ) with lambo doors and your Silverado on air bags ( )

OP..system looks good as i've said before. nothing "wrong" with your speakers at all. I was only talking about upgrading to Competition grade speakers to really make your car a show/SPL Sound Competition car.

But whatever works for you. its your car. enjoy. PM me with any audio questions

 

after you commented on how nice my 150 dollar a piece mtx's were, i dont think a 5 year old would pm you for audio questions lol, you obviously dont know what your talking about.

 

We spent around $2,500... after buying all the stuff we gave this guy the leftovers for himself. I didnt really like the edges of the plexiglas so i sanded them down and it looks alot better because its completely clear.... Im thinking about tinting the plexigals and cutting a scion emblem and a tC emblem out of the tint so at night when the lights are inside it will shine through and look cool... if i dont like how that looks i can get another piece of plexiglas.

 

Ya should have gone with the GM-5100T 760w 2 channel amp instead of the 800 mono because the smaller cheaper one would push those subs better.


Pioneer GM-7100M 800 Watt Mono Amplifier -- rated at 250w RMS x 1 @ 4ohm. Given you've wired each sub @ 2ohm, you're only getting 125w RMS to each sub.

Pioneer GM-5100T 760w 2 channel amp--> Rated at 190w RMS x 2 @ 2ohm.

 

/\/\ That's what i ran in my xB with the same subs
