So i took my car to a show not to long ago and saw that California Customs was having an SPL comp for free. I got some subs, why not? yanno. so i went up to the booth and got the process started. Turned the sub level up to the max (+15) and made sure the amp was tuned. heres the setup
-2 12" alpine type e's (inverted)
-6.5" boston acoustic's up front
-8g kicker wiring
-alpine mp450 mono amp
-sealed box
-Kenwood hu with built in video

this whole set up i purchased brand new, pieced together for about 4 hundred bucks
. To me i must agree it hits, but nothing crazy, or maybe im just used to listenin to it real loud, but the test results suprised me. We the SPL level on the first song to be about 134, then on the next i got it to 136.2! IDK but i think if a 2g wire were on there or a 4 i might be able to get 138-140. Who knows... not to bad of a set up for about 4 bills

 

Congrats. I would like to see what kind of SPL my system puts out, but I have no idea how to check, and I dont think delaware is big enough for stuff like that LOL.

 

walmart carries spl meters

 

are they expensive?

 

i think i saw one in the discount isle for like 20 bucks....lol, but thats at my store

 

Every Walmart SPL meter I've seen tops out at 130Db. Hell the one I bought from there won't read 130. The roof of my Blazer flexes about 2" and in my house it sounds like someone is banging on the walls, everything rattling and it barely registers 129Db... I don't believe it for a second.

looks like they have a decent one for 15 bucks!

What department would I find this in?

 

Car Audio
Should be the same in US as it is here in Canada

 

those spl meters suck... search for a dealer with a term lab meter

oh and if by turning the bass to +15 u were clipping the signal theres a good chance ur number was lower then it could have been.

 

I have one 12" Image Dynamics IDMAX and it just hit 143.3 last week

 

i wanna know what kinda spl meter they were using and were they mounted it cause i find if super hard to beleave that 2 type E's hit 136 db

 

Yea, seems a little high especially considering I bought one from walmart for 15 bucks, and put the music up as high as I could stand and only got 128.2. Im talking to the point where the highs actually hurt you, and the base made the hairs on your arm move....

 

those cheap walmart meters DO NOT WORK i used 3 brands of dm meters at the same time
1= walmart
2= termlab
3= i dont rember the brand

the walmart meter was either giving a way to high reading like 155 db or really low like 122db
the term lab meter is bang on it gave me a reading on mine at 139.6 db
and the other brand every time u moved the mic it would change the results so we didnt keep using it

so there is no way type E's even came close to 136db i would say 128-130 cause there only like 200 watts each

 

It doesnt matter about wattage, its about the efficency of the amp, subs, and box that you have mated together for the system. My buddy has one 10" sub in a box just big enough to hold it, 140 watts on it and it just hit 132.5 on a term lab meter. EFFICENCY is the key.

 

I've hit that with one 10" MTX 9500.

 

your a lier bud sorry to say ...you are right with the efficency but the term lab measures sound pressure and 140watts is not putting out enough power to make a sub do 140db

it took my buddy 1000 watt JL amp and a w7 to get 144db so your a lier with 1 10inch and 140watts






and the mtx 9500 is a beast of a sub

 

the mtx 9500 is a piece of ****. wanna buy one off us? can u take the 8500 we have as well.

 

the 9500 is a great sub you probley are running it off some piece of **** amp. its not my fav sub but its def in my top 5

 

lol im not putting that sub in my car. have u even seen one in person. I should make u a video to show u why. In reality its not that loud, def not clean and has a big design flaw oh ya and its expensive

 

Are you kidding me? I'd like to see the other 4 subs in your Top 5 list for a good laugh then.
