139,4db
I competed in a s.p.l. comp yesterday and got 139,4db not to shabby but i could have got a little more if i had used the octaver in my player but i forgot it was there so sad.gif but i finished 6th out of 16. the guy who won got 148db with two rockford18" 1000w subs, i think it kinda sucks that he was in the same class as i was because i only got 2*12" but what are you gonna do i´m still fairly happy with the outcome, now i will be changing my whole speaker system out and getting new 2*300w 6*9" ts-e6995in the back 2*220w 7" tse175c components up front and 2*1000w 12" tsw1201dvc subs in the trunk. can´t wait to see how it works smile.gif

The main thing you have to remember is that speaker wattage doesn't mean JACK! A speaker has ABSOLUTELY no power. If you go and put in high wattage speakers it takes more power to drive them. If you do not have a lot of money them look for speakers with a higher sensitivity rating, preferrably 92dB and up. Don't worry about wattage as most speakers can handle far more than what the box says as long as they are crossed over. The specs on the box are usually rated from 20-20,000Hz. In a car they should only play from maybe 80Hz up. That essentialy means that you are cutting out the most power consuming and demanding bits of music from them.
So for better results go with bigger amps and more efficient speakers. I personally hit a 141.2 with two tens in a Geo Storm.

are u referring to the ****ty score or the db drag event cause if u are refering to db drag he would be in a different class no matter what because he has 18's. if u have 2 18's and dont have alot of power going to them your stupid anyway.

You're right low power and 18 is stupid. But I would say out of the FORTY or so DB Drags I have judged that classes are divided into watts. It didn't matter if you are talking about 30 10"s or one 18" for that matter.
Gappi, what power class did they put you in and what is your current set-up.

ok tunez correct me if im wrong but in db drag arent the classes divide as such. Street Division
· 1-2 Woofers, 12-inch maximum woofer diameter – 1 subwoofer amplifier maximum.
· 3-4 Woofers, 12-inch maximum woofer diameter – 2 subwoofer amplifiers maximum.
Additional Guidelines for the Street Division:
· Each subwoofer amplifier is limited to a maximum of 4 “non-bridged” output channels or 2 “bridged” output channels.
· Amplifiers used for non-subwoofer applications will not be counted. · Subwoofers may not contain more than 2 voice coils per sub.
· Competitors who qualify for the World Finals must move up into either the Super Street or Extreme Divisions the following season. Once a competitor has moved up, they may no longer compete in the Street Division.
Super Street Division
· 1-2 Woofers – No Walls
· 1-2 Woofers
· 3-4 Woofers
· 5-8 Woofers
· 9+ Woofers
for this class u may use more then 1 amp.n and subs larger then 12 inches
Extreme Division
· 1-2 Woofers
· 3-4 Woofers
· 5-8 Woofers
· 9-12 Woofers
· 13+ Woofers
for this class u may use as many amps as u like. and what ever size woofer u like.
so if this is true that would mean that there is nooooo way he could compete against someone with either 2 18's or some one with 30 10's if this was a db drag event. and i dont think watts is a issue just the number and size of the subs and the number of amps.

Actually yes for the most part you are right by IASCA standards. All the one I have done have been by wattage not cone area. Heres the funny part, it can be looked at in different ways. 2 12"s with 500W would "out-perform" 2 18"s with the same wattage. The reason being is that the 2 12"s would play to a "full potential where the 18"s would be power starved. The biggest reason for the cone area changes that I can see would be the cheater amp. They are a higher cost therefore the people with big money would always win. If it is done at a configured "What power the amp it set to run at" basis, it takes some cheating away. Getting someone to tell the truth would be the hard part.
Anyway, here is a link to look at the true breakdown of what you stated. http://www.iasca.com/definitions/index.html
