Ok guys, after the "1500 watts amplifiers challenge" i took out everything from the sexplorer, is time to move on and try a bandpass for hairtricks using small cone area, but anyways, i was kind of boring and i wanted to try something fun, hitting over 140 dbs with a DAILY box , cheap equipment on small power and very small cone area, all of this things on a big ass cabin 1) Step one: Getting a cheap sub, i found a Pioneer Champion TS-W258D4 350 watts DVC 4 ohms for 15$ , it didn´t look that bad actually, price it´s something like 45$ if you get it brand new if i´m not mistaken Specs: Features Maximum input power 1.200 W Nominal input power 350 W Impedance 4Ω Frequency response 20 - 450 Hz Lowest resonance frequency 37,4 Hz Sensitivity (1W/1m) 90 dB Woofer size 25 cm Woofer material Interlaced Basalt / Aaramid Fibre Reinforced IMPP Composite Cone Dual 4Ω voice coils: 2 or 8Ω Yes Voice Coil bobbin type Phenol resin coated glass cloth bobbin Pole Yoke Type Extended and Vented pole yoke Magnets Double-stacked, high power Terminals Push-type Recommended sealed enclosure 18,4 - 35,9 litres Surround 3-Layer Fiber Woven Radial Surround Technical Specs Nom. Dia.(In) 10 Qts 0,48 Qms 11,52 Qes 0,50 Fs [Hz] 37,4 Vas [l] 17,63 Vas [ft3] 0,620 Vd [l] 0,326 Vd [ft3] 0,01151 Sd [m2] 0,03134 Sd [ft2] 0,337 Revc [Ω] DUAL1.5 Levc [mH] (2000Hz) 2.2 (4Ω) 0.63 (1Ω) Xmax [mm] 10,4 Xmax [in] 0,41 Zmax [Ω] 96.01 (4Ω) 19.95 (1Ω) BI [Tm] 14.68( 4Ω) Rms[Ns/m] 2,920 Mms [g] 143,28 Cms [m/N] 0,00013 Mg.Wt.[g] 2100 VC.Diameter [mm] 48 Eff [%] 0,18 S.P.L.

Enclosure [ft3] 0,80 2) Step two: Get yourself a cheap ass amplifier, i used my old trusty Almani PA1100.2 amplifier, it cost about 100$ brand new, no complains about this little baby, i´ve abused it with 4 mids for about 2 years now without a single problem, of course, since the sub it´s DVC 4 ohms i wired it at 2 ohms P.S: I forgot to take pictures of the amplifier, don´t think you need them tho, if you don´t trust me then i guess i could take some pics tomorrow if you need me too Specs: Almani PA-1100.2 Description * Soft turn ON/OFF * Nickel Plated RCA Jacks * 2 OHM stable operation * Power and Protection LED indicators * High efficiency, heavy aluminum heat sink * Nickel plated power and speaker terminals * All models are bridgeable and stable at 4 OHM * Class "AB" Technology MOSFET PWM Power Supply * Protection circuites against: Overload, Thermal, Reverse Polarity * RMS Power @ 4ohm: 275W x 2 * RMS Power @ 2ohm: 550W x 2 3) Step three: Get yourself some cheap ass plywood (had some scrapp wood on my storage so i didn´t spent anything on this) , screws, glue and wires, total cost: around 32$ 4) Step four: Build your ugly ass box with your cheap materials, box specs: 1.2 cubic feet and 17.5 SQ of port with a 40 hz tuning 5) Step five: Get your ass to my "SPL Gains topic" and use some of the tips i tested over there, if you haven´t visited yet, check it out, use as many things as you can. SPL gains topic Printing vynil 45´s on the pressure corner: DONE!! (no pics) Roundover on the sub hole : DONE!! (no pics) Sexy ass flare using 3/4" pvc strips outside and insinde of the port: Tape around the sub: And finally, metering your ugly ass box on your SUV: Score is sealed on the dash @ 47 hz, plays very nice from 40 to 50 hz, below or above those points it sounds like shit, lots of clipping on that score since i was too lazy to set the gains properly because i don´t give a fuck about that sub lol, so i just burped rolling up the volume knob of the HU and that was it, also, i bass raced a 139.4 using a song from my boy Decaf wich is constant @ 47 hz, with a couple of tweaks i´m sure i could bass race a 139.9 but i´m just lazy as hell since it was just for fun, hope you guys like it

were to put bass port ????????????
fecupe2001 replied to faderbass's topic in Subwoofers / Enclosures
Subs facing forward and port facing to driver´s side, it´s a VERY loud car on the meter if you want to compete -
Easiest and fastest way for me, they always end up looking very nice

DD-1 and my first impressions
fecupe2001 replied to dB Don's topic in SMD Distortion Detector (DD-1) Topics
Yeah, that´s what i love about this little device, looks like it´s fast as hell to set the gains properly, thanks a lot for your review man, if there´s an input i trust, would definitely be from you!!! -
DD-1 and my first impressions
fecupe2001 replied to dB Don's topic in SMD Distortion Detector (DD-1) Topics
I do have access to an O-scope, a very good friend of mine owns one and i can use it whenever i want, but you know how it is, it´s way better having your own tools, i might get that DD-1 in a few weeks -

Maybe it´s time to get the first DD-1 on latin america??? -
N8, same side that your car does Not always you need to tune higher for comps, depends on a lot of factors, for an example, my explorer is louder tuning the boxes around 38-39 hz no matter what the box size or even amount of power you have, pretty sensitive about it

SoundQuest?
fecupe2001 replied to wmrcs's topic in General Audio - Can't find a category for your question? Ask here.
I use Soundquest in my explorer, 4 runs of them, can´t tell you if it´s OFC or not lol, i don´t remember right now actually, but my electrical holds up pretty nice, like my voy SPL Blazer said, if you ain´t looking for comps or anything, you shoudln´t see that much of a difference. I can tell you this, there was a cheaper soundquest wire, i went with the most expensive between both of them, still don´t know if it´s OFC or not lol -
Depends on your goal and space available, for me, it´s impossible to wall with 4 18´s my explorer and get a good amount of port area, so i´m building a 6th order, on my friend´s almera we did port on the middle because he competes at bass race (over here we do it with driver´s door open) and that´s why he didn´t built port on driver´s side, and lastly, i built a few days ago a wall on a suzuki vitara, the guy wanted that thing for demos all day long, he wanted to get as loud as he could to passenger side, so we built port on driver´s side and man, with his door closed the passenger´s side is nasty!!! Tons of people built port on top because it´s the best sounding according to them , i haven´t test any port on top of a wall yet since i´m still a noob about walls, you should get a better input from someonelse

what you guy's think need help plz
fecupe2001 replied to pittross's topic in Subwoofers / Enclosures
hahahaha another awesome avatar, very nice -
My pleasure man, if i were you, i would get an AQ3500.1 , that thing can give you around 4500 watts @ 1 ohm around 13v , go to their web page and check it out, best bang for the buck out there IMO...

ahhaha that´s one funny ass avatar stang, very nice!! -
Is it a dumb question? maybe, are you dumb for asking it?? NOT AT ALL!!! That´s why forums exist, so you can get as much help as you get before doing something wrong; About the question, boxes don´t have to be exact to the manual, depends on a lot of factors, i haven´t look at the recommended box on a manual for a few years now lol, so don´t worry about that. P.S: 2.25 and 2.225 it´s the same thing, you are not gonna harm anything, or even hear a difference between each other, so don´t worry that much mate

my humble sound !
fecupe2001 replied to lton85's topic in Member Videos - Host 'em & Post 'em! System Vids / Off Topic
Not bad man, believe it or not, one of my favorite subs ever if we talk about price/performance, they can get LOUD as hell with small power and they sound pretty nice actually, i´ve worked A LOT with the champion series subs and they get loud on a proper box, ncie vid -
Best input you are gonna get should be from me i´m guessing lol, i´ve seen many people using the C5 but almost no one with the C7, i used a C6 for almost a full year, and i´ve tested the C7 a couple of times on a friend´s car, the specs are on 18v iirc , i clamped 2800 watts @ 3.8 ohms dropping to 12.5v on my old C6 , it´s a beast amp for sure that can take TONSSSS of fucking abuse, mine took lots of vibrations for more than a year until it died, but that´s was the reason and nothing else. The C7 CAN TAKE 0.5 ohms daily if you have the electrical to back it up, 0.75 ohms should be safe if you have a nice batts and alt, that amplifier sounds awesome on music and can take tons of abuse, just know this, you ain´t getting 7K from that amplifier wired at 0.75 ohms with a voltage around 13v , 5K is the most you are gonna get from it if you are lucky...

fecupe2001 replied to pittross's topic in Subwoofers / Enclosures
so something like this What's the specs on this one same 35x50x19 port 33.5x6x29.5 I hope you have enough power to feed those subs, box is very small if you go with the measures you just gave, i would do a port 33.5 x 5.25 x 22 , that would raise your internal around 1.5 cubic feet with a 33 hz tuning, that should sound better than the smaller box with bigger port, that´s a C pillar wall???? -
Box specs looks very good, too bad you have to go with a L shaped port, that drops down your score a little bit but anyways, build that thing, should score and still sound very nice. If you haven´t seen my SPL gains topic at the SPL room, i suggest you to take a look at it before starting to build the box, you can take lots of good ideas from it...
-
I would go with a much bigger box, specially since you are wiring the amplifier to 1 ohm i´m guessing, efficiency FTW , around 4.5 c/f and 2 6" aeros should murder, or, around 70SQ of port, this of course if you have the room available in your car...

Alpine and Kicker Product SUCK!!!
fecupe2001 replied to dagodpere's topic in SMD Distortion Detector (DD-1) Topics
I use an Alpine 9886 HU, 4 panamenian spl records, 3 consecutive 140-149.9 bass race titles and been using the same HU for the last 2 or 3 years now without ANY problems, i guess my Alpine doesn´t "SUCK" at all, oh wait, i know what i´m doing -
I personally love those w7´s , of course, is not a sub i would buy since it´s way too expensive and i know i can get way louder with other brands, but they surely can take more than 1000 clean watts for sure, just saying, as long as OP knows what he´s doing he should be fine! I remember when people said a DD 2512 couldn´t take more than 1000 watts because of the 2.5" vc , a year after getting 1500 clamped watts a piece proved they were wrong, once again, you have to know what you are doing
