Subwoofers / Speakers

Hi- I am going to add a little midbass to my ride (it doesn't really have any atm). I am going to buy 4 MLI-65 midbass woofers. I am going to make a sealed enclosure for all 4 for the rear deck. Any recommendations on how big this should be? Thanks.

So lately one of my friends insists that we "have a concert" every time were in my car because hes never really heard any good speaker setups and mines the best hes heard, but all I have are kicker ssmb6 midbass on ~55 watts and 3.5 coaxials in pods on the a pillars run off the HU. The sound impresses him but if its going to be a concert I want a louder more full sound. I dont know much about what component sets are good and I was hoping for some input as to what I should get, assuming a passive component set will be a decent improvement. SQ isnt the most important thing, I really just want a loud clear full sound. This is going in my honda accord and I only have abou…

I'm not 100% sure that I'll say all of this right, but I'm going to wing it. Let's just say you want to build a single reflex bandpass box, but you want to use a sub that isn't recommended for sealed enclosures. How do you find out how large to make the sealed part of the enclosure?

Right now I have 2 RF T110D4's in sealed box fiberglassed to floor under back seat. I want to up grade to get it a little louder and sound better. The box now is about 1.9cuft I think. I will tear this out of course for new box. Is there anyway to jack up the seat brackets a couple of inches to allow more volume to the box? And still make it look good, and functional. I've always wanted 12's but was told they wouldn't fit. Is there any way I can get better option's with leaving the seat back there? My amp right now is a RF T10001 power series. I will upgrade that if I need too. Is there any customizations I can do to allow me to get some good quality 12's under the back s…

Not sure if this belongs somewhere else. . Okay, because i have a hugeee box for my sub that barely fits in my trunk of my crown vic. ya lol The sub faces upward toward the trunk. Whenever i turn up the volume my trunk piece flexes and moves like crazy. Although it doesn't sound as bad as those 200 watt shitty bass system that is just rattle. The previous owner of my car put some type of insulator in all of the cracks that would normally rattle in my car, not sure what he used. But the only thing that moves like crazy is the dam trunk hood thing itself. If i face the sub toward the license plate there would be about a minimum of 10" inches possibly more , between…

hey guys i was wonderin if any of you guys could help me out an do a free box design for me? i can email you a box design that was done for me but idk if the tuning is correct an i want it changed a lil bit. but i want the same basic design. the box will be for 2 12" fi bl's off a aq2200d. so if any of you guys wanna help me it'll be much a appreciated! also if you guys have any recommendations on specs for the box that would be great. the current box i was thinkin will be 2.5 cubes per sub dual chamber. 32hz. double baffle. any suggestions?

Ok I am planning on getting 2 Fi BTLs Dual 1Ohm, and running them to a Sundown 3500D, but I seen the Mayhems and started thinking, I know you cant really hear the difference, but Im looking for the most, should I get two Dual 1 and run them to a 4500D? the box will be 2.5^3, 32-34hz IDEALLY. Electrical will be big 3, not sure if I 1 or 2 XS3100s, should run around 13+V(you get the point), 220A HO alt. Budget : $7500, gotta love the army bonuses.

So right now i have 2 15" Fi Q's but im starting to get annoyed with them, They are in a 9 cubic feet box tuned to 33 hz (thats probally 7.5 cubes after port and displacement) Anyway they hit the low notes very hard but the high's suck, I heard the can somehow be reconed into a bl or changed into a bl is this true?

hey guys, right now i got the box build already, it's a 11.2 cube box sealed. I was using a bunch of left over wood. one IXL 18 is going to go into it. I could add (3) 4 inch ports and make it a 10.7-ish cube box tuned to 16hz, or I could keep it sealed. it's going to get about 900rms. what should i do? I haven't ordered the sub yet. If I was to do sealed, i thought i'd go with the high Qt. I'm just afraid the 10.7 cubes is too small for ported, or will it be ok? since sealed would be in such a big box, wouldn't the lows be comparable to the ported box? say in the 15-20hz? or not really?

Frankenwoofer aint scared of nothing! First burp Second burp

I'm trying to install them but the post are not marked which is positive and negative, how can you tell which is which?

how can i tell if i have 2 or 4 ohm coils if it dont say on the woffer

Hi guys, My Durango has 6.5's upfront with factory 1 inch tweets and 6.5''s in rear. My plan was to put new comp set up front and a midbass spkr, in rear, but after reading some peoples posts they say rear spkrs. won't be heard anyway. Is this true? If so instead of a 4 channel amp do I just run a 2 ch. and wire it to the spkrs and tweets or just the spkrs and run the tweets off the radio? Thanks for your help.

I'm planing to purchase a lvl 5 15" in the very near future and so I'm working on the box design and I was hopeing someone could give me the volume of this woofer. Thanks...

I was listening to my stereo on the way home and stopped to get some pizza and waited in the car with the stereo on. I decided to not be a prick and I turned the sub off. I missed the bass so I turned my HPF off at the HU, which I usually have set at 63, and the mids actually do pretty well with the bass. I turned it back on and set it at 50Hz and it wasnt bad but theres so much bass im missing with it on. I am going to continue running the HPF at 63 when I have the sub on, but the times I turn the sub off I would like to disable the HPF to the mids to get some bass back. I was thinking of going to the amp and setting its HPF so that if I turn the HU's HPF off, the amps H…

well i could really use some help with my box design.. i ordered a 15 Xcon on monday and i want to start on the box for it.. i have a table saw and router and have built a couple boxes before.. but i am kind of new to this and want this box to sound good,, it will be going in the back of my 06 ford-f-150 fx4 supercrew.. i plain on putting it were my small side rear seat folds... i would like it to be 21x21 then 27-26 tall. ( sub on top ).. i would like it to come out to the 4 cu.ft ported.... they say 26-33 hz..... i listen to mostley rock...hard rock... but i like most music that sounds good.... i love good bass... i am not very good at figureing out all the math...…

I want to put some bass blockers on my speakers until I can upgrade to a set of components. Which one of these would be best to get? http://www.parts-express.com/wizards/searchResults.cfm?FTR=Bass+Stopper&search_type=main&WebPage_ID=3&searchFilter=Bass+Stopper

Looking at a earthquake amp. Says its a 1000d Is it any good and would it run my p3 dual 4ohm. Amp is 50.00

Building a wall, and need input on sub(s). It's in a 1974 Mini, so not that much room, but have thrown out the back seats and the wall is in progress. I'm guessing maybe 12-14cu.ft. total airspace? Will check later. I have a 2 x 1000 W RMS @ 1 ohm OR 1 x 2000W RMS @ 2 ohm amp (Helix Dark Blue 1000.2). What's the best "ground pounder" option for my wall with that power and space? To explain what I like, I have two JL 10W7's in my daily driver, 9 cu.ft. @ 20hz, and love them to death! I want decent SQ aswell. I want it to go deep, only playing 50-60hz and down. Have (3) Morel Elate SW10's for 50-60's and up, which will go in a separate enclosure below the wall. RE XXX-18 a…

I guess I don't know much about this subject. I did a quick search on here and didn't find all the info I was looking for on the questions that I've had lately. To my understanding, it's just the natural frequency of the sub. I'd like to know a little more than that. Recently I saw a topic where some 8's with ~38hz FS were for sale and someone described them to play really low on music, how nice they are for music, on and on. I didn't know if these subs were meant to play lower than 38 hz or if those people just called +38hz 'low'. Correct me if I'm wrong, but the FS is 1 frequency and not including the + and - frequencies (to some small extent) meaning that the sub can p…

Which is better to run my p3 dual 4 ohm sub? With my rockford fosgate t400-4 I can wire my sub 2 or 8 ohm, Which would be better?

I have a 15" sub in a box that is 4 cubes before port and sub. The box has 2 32" ports. I tried google and the search function on here but i couldn't find a way to figure out the tuning frequency of the box. Thanks for the help If any more information is needed please let me know.

Comments are always welcome! -Drew

Any one think there is a better quality and sounding sub out there for the price.

This sub was tested in my 05 four runner. DbDrag style seald on the dash. This is only the 3rd time testing in this vehicle, but it works well because as an suv it has a large cargo area and doesnt have some rediculous peak like my old crx had. I ran into some heat issues throughout the day and this is only 2/3s of what I planned to test. Look for frequency plots in a few days. SPL results From the beginning of throwing the sub in the box i realized I had a decent spl sub on my hands. I started testing with very minimal power, 10.4 watts , just to show the effeciency of this sub and the fact that you do not need to drop 2000 watts on a driver for it to be loud. Afte…
