my new system can i hit 150?

[maljr1980 10+ year member]

Yeah my box is getting rhinolinered tomorrow and installed on Saturday, curious to see how accurate or sloppy the subs will sound and how hard its going to hit

Should I pollyfill? Specs are .88 sealed for max power handling, 2.0 for sq, I'm at 1.5 per sub

why did u go L7s if u want sq out of curiousity? they are in no way sq subs at all.. i had L7s when i was in high school and they were worst subs ive ever owned for sound quality but they were loud... you should have ported them tho if u wanted to try for 150

I already had 2 in a ported box and it wasn't loud enough, so I got 2 more, and didn't have enough room to go ported and hide them under my cargo cover, I don't want people to look in and see all of it. They don't sound bad in a large sealed box, a little louder than the 3 cvx I had, but not hittin 150 now that's its installed. Oh yeah I don't have the patience to order underground subs and wait for them. I didnt have any bumps and they wether got nice so I went and bought the 2 l7's in a ****** flea market box. Basically my choices that day were L7, cvx, type r, mtx 9500, or some RF subs.

Why the fuck didnt you get the 9500s?!!!!

In my opinion what your gonna do will be loud and hit hard, I don't beleive 150db loud though. I won't compare setups, but I have 4 12's in a sealed 6cft box after all displacements in the back of my crew cab chevy truck with no back seat firing forward. With over 4000watts and at a tone of 36hz I term labbed at 135-136db at the windsheild. I really hope you would'nt see this as critisizm or think I'm a know it all, but I really think ported will be the only way you will get to 150db even if your peak tone is 45hz+. This is for comparison only from my experience

I went from 2 12's sealed at 2.5cft box with 1200watts and a peak of 40hz I term labbed 132db.

This upgrade did not yeild much difference on a TL meter, but I can tell ya that it made a huge difference to mine and everyone else's ears and makes my truck rattle way worse then before.

If you can't do ported, then I think your still gonna be happy with your results.

I really hope my post was positive in every way. I really hope your new set up does a 150db because that would be awesome.

4 12s and only mid 130s? somethings wrong with that imo. I had 2 l712s in a 4.25 after sub ported on 2 cheap sony xplods from walmart in a grand am trunck and did 140at headrest on tl

maljr, there is nothing wrong with kicker. opinions are like a****les, every body has 1, some like some dont. I feel they are over priced personaly but who cares. As far as a 150 there is alot to take in to consideration. Did u upgrade the alt? xtra batts? size wire, both powers and speaker. With the right box and power yes u can get a 150.

no one will ever, ever. hit 150 in sealed. I do not care what your friend told you, hes a dirty liar.

I have a stock alt, big 3 in 1/0, HC 800 in back with 1/0 run to it. 4 gauge run to the amps as that's what it takes and 8 gauge to the subs. It does hit loud and hard, haven't properly gain matched my amps yet as all subs share a chamber and 2 amps run it, kind of tuned by ear on the conservative side so maybe I can get more power, but if I were to compare to my 3 12" cvx from last summer, its about the same, maybe gained a db. Hard to say without a term lab and oscope for tuning, but with 70% more cone area and 50% more power than before I'm falling well short of 150, I'm thinking in a 10 or 12 cube ported box it is very managable

well thats stupid! the cvx's are the l7 motor in a round sub. a hybrid of l7 and cvx's!

Hmmmmm not sure if trolling //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

heh I'm thinking about using my MA Audio HK602sx to power 6 type Rs in 1/3 ohm loads at some point. Need more trunk though the Cavy just won't cut it.

Blah' date=' I don't see it personally.
maybe on the AC mic[/quote']

cant do a ported box, have to keep my stuff on the d/l and hid under the cargo cover, and i personally think sealed sounds better and hits harder, may not vibrate and meter as loud but sounds louder imo

if i was trolling id tell you i have 10 pyle red label 12's, 4 boss 4000watt amps, and all i listen to is justin beiber, my shits gonna hit!!

Ohh boy //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

You can't do a ported box but you have space for 4 12' L7s? Have you ever heard a ported box?

Build a new box.
~7.5-8cuft net, 3-6" flared ports. Subs up, ports back. Have the ports about 6" from the back hatch.

Start w/ the ports full length, and cut them down as you test. (you will likely peak out w/ the ports ~10-12" long)

When you get to your peak SPL w/ all 3 ports open, your set for competition. The beauty of using 3 ports is this....plug one port (center port) and play it daily //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

It will tune FAR lower and sound good for daily beating.

Kicker is about the same thing around here...

Smh.. What are your dimensions?

Yeah I'm pretty sure with 6, if not 8 and another amp or two I could hit 150 sealed, u realize what u just said right? I'm sure it would be fairly easy with some level 5's or 18" btl's to pull a 150 sealed

 

[maljr1980 10+ year member]

Yes its the same motor, the point is i had 3 running off approx 1800 watts, now i have 4 square ones, 70% more cone area, and 2600 watts, my question was wether i could gain the 5 db's needed to hit 150, after the install in a sealed box like i had last year I've concluded its not happening, it would be close with a ported box, but very achievable i feel
