I asked this question already didn't i?

lol...How big is your box now per sub anyway? If you go a good amount bigger you could lose a little bit of the higher frequency bass because technically sealed boxes still do have a "tuning". The trade-off still isn't any near as bad as with a ported box though. Shit sometimes you won't even notice & and sometimes i heard people gaining all over the spectrum because the original box was "choking the sub" so it's a toss-up depending on how big the box is now.

It's only like 1.7 per sub right now.

I just remember my dawg had (2) MTX 8000 15's in his shit yearrrrrs ago, and he couldn't even play "bia bia" cause that shit wouldn't hit the note. I don't want my music to be like that. I wanna be able to play EVERYTHING and it sound good. It's pretty much like that NOW but the lows could be a lil' better.

Maybe I'll try that polyfill.

DAMN YOU CHOKING THOSE 15s, GIVE THEM SHITS ATLEAST 2.25 , MY CVR 12s had 1.7 per speaker sealed up, and boy did the low end play and still punch the shit out of ya, i use to play notes so low you couldn't hear them but you would hear shit on my car shaking like a mutherfucker, and i still hit every note in the book, damn near make me wana go 8 pack with re se 12s

J, how much more space can you provide? & Polyfil that box, even if you get a bigger box.

x2...Did you get that electrical up to drop that ohm load yet?

I aint booming yet. You must be referring to J, about dropping the ohm load on the AQ2200?

I got plenty of space to provide. The way it sits right now I could fit 2 more 15's if I wanted to. Alot of room in there.

Go ahead and build a bigger box. & still throw some polyfil in there.

If you can provide me with some measurements (Length,Height,Depth) of the useable space you got, I can draw something up for ya.

I guess I could do somethin like this. (if this shit here dont bang) SMH

yeh that gotta bang but I have no doubt he is getting port noise. Only thing i'd change is i'd take that divider that divides the port up so you get a lot more port area.

Off topic, L!no, anymore pics of your install? And how were you digging those T3s?

And ive had alot of exp with the Kicker CVRs, J a bigger box would give you the deeper lows you are looking for. I went with a big box for a pair of CVR 12s and the box was weak on the upper notes, but would drop to the gotdamn bottom....didnt need alot of power either.

All you need is your box to be around 2.25 to 2.5 each sub and you should be golden.

no hate but that looks like alot of cancellation. get the measurements, and do your subs face the same way as in the pic?

whats tha difference in doing what he did n having subs up port back and no his car doesn't really bang he has a video of it pulling up with the beat on didn't look to impressive to me, and def not enought port area for 2 15s

And the almost finished pic...never really got around to 100% finishing it because of skoo


and it's been the hardest hitting setup i have had. It's the loudest around 45hz and i'm tuned to 35. When the weather clear up it'll be time for me to break it down. It was almost as loud as i wanted it to be. Added another batt and set the gain where it was supposed to be, but it's still not there yet. Haven't found a second BTL so i think imma build a 4th order with these just to see if i like the sound.

how do they handle playing below tunning alot, that was the only problem with my last setup, subs didn't like playing below tunning at all, even though i was over powering them

Well I'm supposedly overpowering these subs but no matter what i do to em I can't get em to stink at all. But playing this song Snoopdan remixed over on ca.com with that like 15hz note i can get the coil to slap bottom plate if i full tilt it.

oh ok

Well in a trunk, that setup is not the number 1 choice unless you trying to make alot of noise.

But the difference in that setup, and all subs up, port back is that with the subs up & port back, you have direction. as your subs moving in, the air is going out the port so it's less cancellation that 2 ports, 1 up and 1 back, all that pressure is meeting right at the back curve of the trunk over the license plate. Its fighing each other cus there is no sense of direction flow.

Like I said it would be good for someone who wants alot of noise. There isn't 1 bit of SQ coming out of that. & before anyone as, there are Ported systems winning SQ comps.



NICE!!!!!!!!!!!



That nigga over there lookin like this --->

Lino speaking in audio head terms, break it down for my audio declined folks, the subs bottoms out @ 15hz if he has it up all the way.

You can't hear 15hz , you can feel it tho! But 90% of music doesnt even stoop down in the 20's hz.

Thats damn impressive to be tuned at 35hz.

ok i gotcha (referring to the box question in the imp)............ and naw i knew what he was talking about, just didn't care to speculate further on the subject....... dont turn into another caps cause i know when subs play to far below tunning they are basically free airing little to no compression inside of the box blah blah blah blah blah

I know you knew that, I was referring that to those who may read it and not know what he was saying. But that smiley was for you cus I know ya responce was your way of saying, "i dont care anymore"

Another caps????? I will never be a phoney know it all, failing scam artist, and habitual liar.

oh i take that back then you ain't another caps and yeah your right, i was thinking that

I need to hurry up and get this box builder program so I can be on point with these designs, Tired of running into big mouth people who swear they can do this and that then when it comes time, they wanna ignore ya and hide.,

ok another question, what would be the difference in sub up port back in a trunk than a suv, i see some people say thats optimal in a suv, wouldn't it react the same in trunk, ignoring tha fact that there is a backseat separating the trunk from the cabin

Nothing to cause cancellation in the SUV, trunk.backseat cuase cancellation in trunk

The main reason in my opinion is because in a trunk you have a limited height you can go. The sub has to be a certain amount of inches away from the trunk lid. Plus if the sub is real close to the trunk lid, I can almost guarantee that the box is too big for the trunk and you'll be choking off the sound from getting in the cabin.

oh ok coo, so basically only the back seats makes the difference, but my rear deck is gone be damn near deleted so that would allow alot of that bass to escape, and therefore reducing cancellations, am i right or wrong????



naw box is only going to be 10 cubes, and subs will have 3-4" of clearance from the trunk lid, and still have room for sound travel over the box and around the sides, only reason i have to do subs up port back is because of the number of subs i'm running, box is going to be no bigger than that black imp posted with the 4 15s solos, so subs won't be getting choked, still able to breath, but i know what you talking about when people stuff they trunk with a big ass box and them bitches can't breath

Yea have a minimum of 3" from an opposing wall, same rule of thumb with ports.

x2...if you gonna have 3-4 inches of clearance you'll be str8.

man have yall ever seen real world power testings of that old Clif Designs CD4800.1LX, the guts look different from any other amp i have seen, and have some very good spec numbers but just don't know how true they are, wondering if any of you know, here goes specs and gut shots, that bitch pretty damn long too

Clif Designs CD4800.1LX
5200rms@1ohm-13.8volts
12,000rms 2amps linked-13.8volts
True .5ohms stable
6kw@.5ohms-13.8volts

wouldnt doubt it. them and ma audio had ties, both old school products were badass.

i just got an old kicker amp. first 6channel kicker made, gotta get this fixed cus its nice. rated at 35x6 @ 4 ohms @ 12volts....with (2) 30 amp fuses

You got a nice pickup, I remember that amp, I believe it was the Impulse series, but its been so long im not sure. Every kicker amp I ever owned was well underrated, that amp is more like 50x6 @ 4ohm.


And yeah, Cliff Designs was the shit, too rich for my blood back then lol, but that amp does look beast though.

Very nice homie, looks clean, and I bet it sounds even better....I hope to have my 18" installed in the coming months, found a guy outside ATL to build and install the 4th order for me, just got to pick up somemore odds and ends, plus money has been soo slim lately.

Yehh i feel you on that money part. For me it's Christmas+tuition and books+girls birthday aint no joke lol. But man how much of a difference sealing around the box does. Today I ripped out the foam from around the sub box and its still loud but it feels like i lost soooo much pressure. Tomorrow Imma destroy the box and then Sunday i guess it's time to try to build this 4th order.

Sounds good, and I can imagine, im firing my box straight through my rear seat, then getting my local interior guy to cut a slot in the seat and recover it so it looks factory. Hoping to get max output inside the car, and retain use of my backseat if nessacary.

Going with the T3s with your bandpass, and who did your design?

yes its the impusle amp, its big. teezy that setup gone be nasty, everything inside ya car gone shake like a bit. lino, im jealous of ya for the moment lol. gotta find me another job, they straining over here man

Yeh I wanted to keep my backseat but now i have some glassed pods for horns and mids so thats out the window.

Imma design it myself. Don't plan on keeping it for too long. Just want to try it out since EVERYBODY is switching over to em. What imma end up doing is making the sealed section small as I can and the ported as big as i can tuned to around 55hz. Should be around 2.5cubes playing into like 7+cubes ported Probably gonna end up being peaky but I'll see.

And this morning I noticed that it's not that I lost a lot of pressure at all. It's just different. Before i had to roll my windows down to feel the pressure on my ears. Now I can feel it with the windows up, but with the windows open it gets quieter now. Imma play with it a little bit more before i rip it out today

i was gone scoop it up but dude sold it already

Best thing to do now is design it yourself, for some reason these fools on these audio sites are acting shady lately, and plus you do it yourself, you just gaining experience, bass box pro is all you need, shit thats all the "designers" use. I aint paying a fool $20-50 to design then another $150 to build when I can get the whole program for $130 via parts express and do alot more.



If you still choose to go (4) 15"s sealed, do like this, its a SEALED blowthru., it looks like a 4th order but isn't, its just two sealed boxes enclosed into one enclosure. There is no loading wall or port so its still sealed, just an opening that be pushed up against your arm rest. ( and dont put those dividers in between.)

My Kicker Impulse 356xi (old school) 20" Long

isobaric loading

Isobaric loading? Your subs have to be real close(basically on top of each other) for that.

Think about clamshells. & the 3" rule.& the BP setups you seen from my area...

oh ok

man i'm like fuck car audio right now, maybe i'm thinking to hard or whatever, but all i know is when i had a small setup (hifonics 1600 4 cvr 12s) i had no fucking problems at all bro, for got damn a whole year, each time i step up setups i encounter a problem, when i went up to the hifonics 2600 on 2 strokers, dumb as shop build my damn box wrong, blew the subs and had to have another shop build a damn box, and i had to recone the subs and finally got back to playing with no problems, then after that, stepped it up to a 5k amp, ran into all kinds of problems with that, subs didn't like playing below tunning, damn fuse block on the second alternater shorted out so it wasn't even charging causing my damn amp to blow, not to mention fucking up my damn trunk that still ain't right, i hit a damn bump on the interstate yesterday, and that bitch just popped open for no reason smh, maybe this is telling me something, but you know i'm a hard headed as nigga i ain't gone listen but got dammit i wish i would

sorry for the long vent, alot shit been going on lately and this smothering ass female don't make it no better, this bitch talked to me from 7:00pm to 6:00am this morning with maybe a 3hr break in that 11hr time frame, so i finally get off the phone and you know what tha bitch had the nerve to say before i hang up, to text her when i wake up, bitch i just been on the phone with yo ass for bout 7hrs, i don't wana text you when i wake up

Man like I said before, more power = more problems. Just like with motors, high performance parts working together, one lil mishap and boom boom boom, and I aint talking about bass.

Simple shit usually does best man. Fuck all that high priced, multi-functional products. too much to deal with.

I'm an old school car dude, I dont want a lex or bmw or audi but after working in a car shop for a lil bit and seeing the price they pay for maintenance, or lil simple reapirs, shit have me lookin the other way. 1 thing mess up and everything follows behind it, I told yall about dude who gave a jump someone in his 3series BMW using the battery which is in the trunk....$1400 fix cus he blew 3 on board computers, not supposed to use the rear battery, they have those jumper blocks under the hood.

& damn at that female situation, mine already know I dont talk on phones, text or in person. and shit....my lady live with me now...

man fuck these hoes
