dude is was like a 29hz tune i think

 

118.6db

alpine 9856

13w6v2

custom ported box tuned to 28hzs

autotek ss1900.1 amp

0gauge

not fully tuned yet

 

only 118 db with 750w??

that cant be right

 

db- 157
sub- legacy 8 inch 8 ohms (110 watts rms)
amp- (legacy 200 watt max 4 channel)
deck- stock radio with a casset adapter
mids and highs- walmart roadmasters

no but seriously...
2 15 inch kicker comp vr's with a ported box that was fin huge...dual voice coils wired paralle
2000 watt lanzar amp
148 db

 

x2 if you play your cards right you can usually get about that with door speakers

ya i dont know about that

 

2 12 inch 08 Kicker L7's tuned to 36hz (slot vented) --looking to sell for 9500's
powered by a MMATS 2100.1 amp (1550 rms)

street wires 1/0 awg and rca's
two kinetik hc1800's
stock alternator

4 Infinite Kappa's powered by a class D 4 Channel Alpine amp (PDX4.100 )

With my Kenwood DNX9140 I get 150.x depending term lab (5 volt)

with my older Sony Specialty Series (150 dollar lol) radio I was hitting 151.x (4 volt?)

 

told you it wasnt tuned...break in period still haha =] and im taking it all out and matting my car this week and im trading for a new w6 so ill have to break in period again i hope i can meter around a 140ish

 

my box was tuned higher than that so mine should be a little louder..... maybe 150db isnt as loud as i thought it was


and do you mean DD 9500s or mtx 9500s

 

2 10in power acoustik pw3 subs (800 rms each)

1 power acoustik lfa 4000 watt class d (1700 rms at 2ohms)

1 db link 4 farad cap

4 gauge wiring

Custom built bandpass enclosure

Keep blowing the subs..... anyone heard anything good about the pioneer premiers?

 

i used to rock old school premiers...i loved emmm i dont know bout the new ones though

 

they are ok nothing great thou. dont pay attention to the rated rms numbers because they are bullshit. put 1kw to a pioneer champion and see what happens

not all meters are created equal... i can get 151db out of an audiocontrol without a car or speakers

hopefully DD because the mtx 9500's suck. infact we had one at the shop that was like sorta broken but still played (cracked dustcap and the terminal broke off but coil and everything was perfect) after much debate we just threw that bitch away

 

Im running two 12" hypnotic zen series subwoofers in a ported box, powered by a memphis 1100 D amplifier. They are running at 1ohm and at the local USACI contest i hit a 140.4

 

damn makes me want to go buy a db meter and find out

2 12" Audiobahn AW1206T Subs Bridge to 1ohm
1 JBL BP1200.1 amp approximately 1350 watts RMS bench tested (Tuned to 33hz)
Custom Fiberglass sub box ported and tuned to 33hz
3 Farad Capacitor
4 Guage wiring

 

lol buying an actual term lab meter is pretty expensive but i bet a local shop might have one.... i dont even remember seeing a pic of you whole setup when its all said and done

 

lol slacker...I know I can buy a db meter at RadioShack...quality wise I dunno...

Another pic:

o boo only 126db

 

ya we actually have one of those meters at the shop as well... the only thing i found it was useful for was measuring to see if some sound dampening i did made a difference (passenger side vs drivers side)

Even if it did go higher i wouldn't buy it to measure bass output

 

you think my lfa power acoustik amp that puts out 1700 rms at 2 ohms would be ok running two pioneer champions that are dual 4 ohm? idk the rms wattage on 4 ohm of the amp.

 

whats the model of the amp. assuming its actually rated at 1700 it should work well because those subs cant take 1k rms as they claim and the PA probably wont produce its power rating anyway either

 

who has a good meter?

 

TermLab
http://www.termlab.com/

 

LFA1-4000D. says 1200 rms at 4 ohms on PA.com. and with my bandpass box the subs magnets are in the same sealed enclosure. I dont want to change the box

 

you should be fine at 4 ohms. 5-600 per sub is much more realistic

 

haha back in the day my friend had a Mazda with the loudest system in the county,

I had my Cavalier it was pretty loud but not as loud, but my advantage was that my system was crystal clear, his was just a bunch of noise.

So I'd always take him in sound offs.

And Yeah that setup for the OP looks fucked.

 

Whats the difference of a 2 ohm sub running at 275 watts and a 4 ohm sub running at 750 watts? or is it the other way around...? idk
Someone please tell me the difference lol THANK YOU

 

um one is 275w the other is 750w. the ohm or impedance only changes what amp u need to get to run full power. there is no gain either way
