you need to make it clear what you are looking for either spl or sq also how much power do you have for the sub(s)

If you want LOUD and your budget is open, fully loaded BTL's will satisfy your SPL needs.

a BTL would most likely be louder than a W7

how much power did you have in mind? 2000wrms, 3000wrms, 4000wrms, 5000wrms, 6000wrms, 7000wrms, and god forbid 8000wrms? lol.

anyways if you must go with fi audio, i would recomend the btl's. they get really loud. but for spl subs, they have a clean sound to them as well. to run 4 15s you gonna need alot of power. at least 10,000wrsm. so my advice to you is go with 2 18s with around 6000-7000wrms amps. you will really need to upgrade your charging if you haven't done so. also gonna need some extra batteries in the back.

now if that seems like too much, you can go with their BL lines. only gonna need around 2000-3000wrms to run a pair of 15s or 18s.

^ And you'll still need to upgrade charging. Just not as much.

does your friend have that setup or something?

i think 4 15 inch bl's with 4000wrms have a shot at being louder than 6 13w7 on 3000wrms or 4 12w7 on 4000wrms.

If you have the room go with 4 18'' BTLS and give them 1.5k RMS each for 6k rms total. You should be good with that. You might as well step it up if you're going with a setup like the ones mentioned.

noooo not maybe even a alt. its a must. before you go and get all that stuff, you should get a high output alternator first. it shouldn't be hard to find for you car.

Jake knows what he's doing Andrizzle. He liked his ED subs over the Havocs so that says something.

we wouldn't know considering you havent made a vid or anythe driz... you ftl.

evan, just because you have 4 18s doesn't make you more likely to need electrical upgrades. it's the amount of power you are running. not to mention you said you want to beat 6 13 W7s then you say you want "nothing to crazy?"

I know reece, I owe you guys videos like hardcore. I feel bad for it, school is kickin my as$ right now so work with me here :]. Ill try for something this weekend.

And Rob, I dunno if you saw the thread about Jake being dissapointed. But his port was pretty constricting for the size of the box and the drivers intruding into it. I feel like the box I have built for my 15's is almost ideal. I am very happy with it.

Ill vid for you guys soon.

Well four 18''s will get louder than four 15''s on the same power if given the same suspensions.

Mach5Audio MJ-18 Single 4 ohm

MJ-18
The simple, yet elegant looks of the MJ-18 makes it a desirable choice for home theatre and car subwoofer systems. The MJ-18 is used extensively by DIYers for infinite baffle configurations where bass reaches sub-harmonic levels. Its lightweight craft pulp cone and thick foam surround allows for tight, punchy bass, while the 8 pound magnet structure ensures control of the driver through a 3" voice coil. Its a serious sub, for serious people.

Power Handling: 600 watts RMS

Sensitivity: 93.4db (2.83 volts)

Impedance: 4 or 8 Ohms (SVC)

Outside Diameter: 46cm (18 1/8")

Mounting Diameter: 41.9cm (16 1/2"")

Depth: 20.3cm (8")T/S Parameters - MJ-18 - 8 / 4 Ohms

Fs = 30.4 / 28 Hz
Re = 7.2 / 3.2 Ohms
Qes = 0.39 / 0.34

VAS = 243.8 / 208.4 litres
Sd = 1029.2 cm2
Xmax = 12 mm
Cone Diameter = 36.20 cm

Recommended Box Sizes:
Sealed: 80 litres (2.8 cu. ft.)
Ported: 128 litres (4.5 cu. ft.) 30Hz tuning
EBS: 250 litres (8.8 cu. ft.) 18Hz tuning


Shipping Included In Price

Price: $116.00

or this one for 250.00 and is said to have more low end but needs a huge box as much as 7.50 cubes tuned to 30 hz and 5.50 if you tune to 35 hz but like I said not as punchy as the cheaper version on the higher notes but either mach 5 audio sub will work on low power 600 watts for the cheaper ones each or 800 watts for the more expensive ones
