I would love to, but being my car is so small, big amps are out

Hey PPL, Need some advice. I'm building a demo/comp car here and Japan, and of course DC audio will be the star attraction" My question / problem is, which would be better 2 10s or 1 12. My car is a "Honda Zest" http://www.leblogauto.com/2006/02/honda_zest.html I know its not in English but you can see what the car is like. For power, I'll be using a crunch gp pro 3000d amp and 2 12v batts.

It's already been said but.. you got a heck of a fan buddy. It must be nice to be at that level!

I think I'll be hanging out here now. I got MY pen(s) and books ready! Since class has began, I have a question for ya. in your 2003 build, how many cubes / liters was your box? and, how do you figure your cubes with the angle boards? I got my box done and its 52.61 cubes right now and tuned to about 50Hz doing a 56 / 57,(no angle boards installed yet) I'm trying to get it down cubes down and the Freq up to at least 65Hz. This is where I was told that astros play best.. Teacher.. advice please

Steve, I just peeped out your tear down and rebuild. All I can say is that, thanks to pics like this, it inspires me to keep going when I'm ready to quit! I'm in the mits of doing my astro for DB Drag, and taking her apart seems to be the biggest job. I'm trying not to even think about the box build. I also noticed that your almost a one man operation, same here and its no joke, after doing your day job and come home to do your night work is a killer, but again looking at your work. I know in the end, it will be worth it! Thanks steve, keep the pic coming, they help and inspire more then you could ever imagine.

sounds good, keep us posted. if possible take some pics as you build. The more you give us, the more we can try to give you!

No need for 2 boxes!! 1 box, changable ports. Unless you just want to build 2 boxes

Did some more checking, as for ports, you can do changable ports, the would be your best bet if you want to walk the line between comp and street.

Boss man, I'm not a pro at this but I do suggest that you chamber each sub, reason being is that if one sub goes, the other 3 subs will be off as far as cu.inches is concerned. Also, a street box and comp box are not the same, one your building for ground pounding(street) and the other (comp) is for the mike/sensor.not your ears!! depending on how serious your gonna get, I would stick with the street build, it would sound better. Comp boxes are made for 1 note/freq. If I'm wrong, I'm sure someone will correct me.

Tony is a Great guy! I met him at MES here in Japan. Steve your name came up a few times!hehehehe Steve, If you get to talk to tony, ask him about the girl at the MES show!!!!! watch him bust out laughing!

I followed his build, though about it, but being here in Japan and building it on my own, Not willing to trash my stuff again. gonna go simple this time, besides, I can get more advice on a box build that mostly everyone is using. :w00t:

I bit scared of the bandpass design, I built it wrong last time and It cost me a recone, and living in Japan, a recone can be expensive! but I did want to try a design that I saw a while back, the same type of design that is in scott owens truck.. the tube design, I hear dante and some others are using it. I have no idea on how to build it or tune it.. suggestions please.

Pretty loud man :w00t: x2 The test bed will be my accord wagon, the coop da greasy will be the astro. gonna add 2 more D1's to the mix. and 10 moe batts :weight_lift: Gotta break the 160 mark this year!

There has been an update since this post started!! the autoteks are for sale, I'll be using 4 goliaths and as many 16v batts as possible in the accord! :^ so it goes like this: 4 Goliaths 10+ 16v batts (another 10 on hand!) 2 ATOMIC apx18D1's ported wall. size tbd Moe power :nuke:

Any pic's?? :shifty:

Hammerdown, ya got that right, its costing me almost everything I got :rip_1: to become Japan's champ :w00t:. as for the edge, I was thinking the same thing, ripping out the front and building it up ,then replacing the everything to make it look normal! :whistling: As for the box, My van is virgin, nothing has been done to her yet! I will go ported wall with 4 18's, 4 Goliaths and 20 16v powermaster batts! :weight_lift:oh, I forgot to say, I also have a 350amp alt included! :^ :^I'm trying for 160+, if everything is done right, what do you THINK I will be seeing? a ray of sunshine please, because when this bill hits, its gonna be dark for a long time! :'( :'( :'(

5k on shipping alone not including japan custom taxes etc. batts + shipping + japan tax= almost 9k! :'( :-

dam, no replies from the astro guys???? :'(

Some pics would be great! Right now, I'm a one man team, My sweetheart still has not been striped yet! so any pics would help a lot! I wanted to do steel and crete, but again, I have no idea on where to start... besides the gutting part! LOL As for cheatin...They cheated first! I was running a basic 12v system.. everyone else was 14 and 16v! fair is fair! Hey, another question. about batts. how do I wire 8v batts to get 16v to the amps? lookin at picking up at least 20 golfcart batts.

PPL, I in the pre-stages of building my astro, I got the equipment part done, box design almost done, but now the sound deadner delimma.. Since over here in J-town (JAPAN) they don't really check things like back home. USA. I was thinking of using fiberglass to sound deaden my doors and roof! SD over here cost a ton of money, and foget about importing it! I wanted to use Magic Mate but just too much right now.. :V My idea, since I'm in SS, remove all the plastic in the front area, FG everything I can, and put the Plastic cover back over it.. so it looks like nothing was ever changed! but under neeth, everything is sealed and hard as hell! :^ Your thoughts please. And before anyone asks, we only have 2 brackets here.. SS and EXTREME, and the only difference is the front is done in EXTREME, after that ANYTHING GOES! > :-X :V

how about for 16v batts.. same suggestion? My new baby! can't help but to show her off. She's gonna be the TYSON PUNCH of DB drag over here. The exteme king over here is doing 160.4 out of a Benz! > I'm in SS. there are no classes here, Just SS and EXTREME. so my goal is to knock out the SS king who is doing 156.* with 7 RF T2000bd and 8 turbostart batts! off the big chair, then its on to the extreme class. where 160.4 is the record her in Japan.....FOR NOW THAT IS! Any advice you can give me on building this machine to U.S. standards would be welcome. :^

No advice from all you Pro's!!! :'( Dam, this is what I get for living so far away... :'( LOL

I will pickup 4 Hifonics goliaths over the winter for my new setup. ;D Question, how many 16v batts do you suggest to give these monsters? This will be an all out SPL vehicle. (astrovan)

Gotta agree, using sweeps heats your coils up quick and it also pulls battery power , so by the time you get to the sweet spot, your coils are hot and your batts area semi drained. :-[ Trust me, I learned it the hard way. :'(

To all the SPL astrovan users out there.. what are some of the do's and don't of this van. My team mate and I are now really thinking about switching. All the big boys are using these vans so I know they can get hella loud! It will be walled off, holding 2 18" subs, 4 goliaths and 8 16v power master batts. It will be all out SPL, (SS 1~2) I know I will use a ported box, but what W D H (cu.ft) measurements worked best that you know of?
