  1. I'm not seeing the new designs if they were posted. I know designing boxes requires time to tune correctly so I'm going to condense everything down to this post for you to make it as easy as possible! At some point, we need a clear way to compensate you for your time and troubles. $200+ seems fair but we can figure that out when its done. Can't remember if I said it, but thank you for taking time to help me with this. I really do appreciate everything that goes into helping an internet stranger. I've spent a good deal of time over the years helping others on many forums so its nice to see there are plenty of people out there still willing to help. Vehicle: 92 Jeep Wrangler Hardtop with no doors Big 3 - 200a alt. (on order) - 1/0ga wires - 3 batteries - 3 300a fuses box size: 42" Length x 36" width x 18" height (height: up to 24" if you need more volume) I'd prefer two ports for symmetry - If one is better, just put it in the center if possible. I don't care how complex it is, I have a woodworking shop in my basement and a whole winter to build this. Amps: Rockville DB16 2000w RMS (x2) Subwoofers: CV st154d (x2) RMS Power 1200 watt Subwoofer Size 15" Subwoofer Voice Coil Impedance DVC 4 ohm Voice Coil Size 3 inch voice coil SPL (dB) 89.3 Re (Ω) [series] 6.5 Qms 2.8 Qes 0.34 Qts 0.30 Fs (Hz) 24.8 Vas (L) 123.0 Cms (mm/N) 0.133 Mms (g) 310.0 Sd (m2) 0.081 BL (T*M) 30.4 Xmax (mm) 16.4 Pwr (W) NOM/MAX 1200/2400 DIMENSIONS Total Diameter (A) 15.35 Inch 389.9 mm Mounting Diameter (B) 14.07 Inch 357.4 mm Screw Hole Diameter (C) 0.216 Inch 5.5 mm Mounting Depth (D) 9.48 Inch 240.9 mm Magnet Diameter (E) 8.45 Inch 214.5 mm Hole Diameter (F) 14.75 Inch 374.7 mm Displacement (ft3/L) 0.191 Cubic Feet 5.4 L 
  2. hard top. I've been thinking about the box. I'd like there to be some symmetry to it if possible. Two ports would be ideal.

    its cheap, but is it that bad?

    would have it been funnier if I said 5-10db? lol
  4. Yes. Rockville DB16 2000w RMS (I was mistaken, not 4000w RMS). I'm sure one isn't going to be enough for these subs so I'll order a second one. Two 15's with 4000w rms total in a top firing box with ports please.

    I just completed a low budget build for my friend. I'm sure its a little better then that pre-made kit that you linked but who knows without a back to back comparison. Parts list: Rockville DB14 1000w RMS - $120 12" Cerwin Vega V122D Subwoofer - $100 Ported box - $50 Boss Audio wiring kit - $19 Boss 2 Farad Capacitor - $30 Misc. connectors - $12 Total = $331 I should mention that he has a $400 Kenwood headunit (not sure which model) with a factory bose 8 speaker sound system. The way I look at it, 10-20 years ago it would take 3 times the money to get the same experience. I'm impressed with the result. Got 130db out of it so far in his Audi A4. A bigger box should net another 5-8db. Its utterly amazing what you can get from a cheap setup. I recently purchased two Pyle PLB8 8" subwoofers ($19) to try out the ultra low buck equipment. Sadly, I'm impressed with those two. Got 114db out of them earlier today. Sound like shit though
  6. Sorry shredder, work picked up so I've had no time for this project. Well some things changed over the last month so this isn't going to work anymore. Here's what happened if you're interested. Last week I gave my friend my Rockville DB14 1000w RMS amp, a set of Pyle PLB8 8" subwoofers, sealed box, 2 farad capacitor (he didn't do the big 3) and some wiring to get him back into the stereo game. I hoped some cheap equipment would give him the bite. We spent 12 hours taking his Audi A4 apart, professionally installed everything by making it look absolutely factory original. Powered up the Pyles and found that we couldn't get more then 104db out of em'... It was the end of the day, my wife was calling for me to get back home; We were pressed for time and scratching our heads. Question was; "are those pyle speakers really that bad?" We had no time to find out. I ripped the 12" Cerwin Vega subwoofer out of my jeep and hooked it up to his car. 130db right out of the gate. Told him happy birthday and drove away. I got home cracked a can of Sierra Nevada Pale Ale and ordered a 15" Cerwin Vega ST154D Stroker 4 ohm 1200rms subwoofer with a generic box for now. Embarrassing part is, I don't know anything about this subwoofer. Is it good? Mid grade or low end still? I've read good things about the stroker series. New plan is to run 2 of these subs in a custom box. Is there anyways I can compensate you for your time on this design?
  7. That's great but there is no supporting evidence that the DB series of Rockville amps are prone to burn. This site seems to hate anything that affordable which is understandable. No one wants to recommend something that, perhaps, may have a risk. I understand the risks, so don't worry about it. ;p You willing to help design a box?
  8. Cheap is good in this case cause the vehicle lacks security. There are no doors, no locks, nothing to stop a thief from jacking the equipment. Perhaps I've provided to much information. I'm looking for a box design to meet three 12's in a maximum space of 42" Length x 36" width x 18" height. I will pay for a box design that meets my simple requirements; I'm flexible (provided a reasonable argument) to meet my goal of a top firing box with options of two 15's - or one 18 to any one that wants to design it. I found of video of the DB16 on a dyno, its not that bad. https://www.youtube.com/watch?v=ZVlbCm034F0 Please don't get bogged down on my personal risks here. I just want help with the box design please. Paid. Of course.
  9. Total overall length in the rear is 42" x 36" width x 18" height. My thoughts were to leave enough length for a battery box to the front. If the extra space is needed for the box, the batteries will go else where The amp is rated @ 4000wrms @ 2ohm but I assume a <20% loss netting me closer to 3200wrms. After deliberating with a friend and a few beers. We figured we could run 3 @ 1.33 ohms with this amp for short excursions. Running below 2 ohms should net me some extra power... right? That's what we figured anyways. If the amp melts I'll upgrade to something different. If it pops the subs, I'm only out $300. Then I'll have an excuse to upgrade.
  10. Yes. 3-4" inches rearward to the gate with 12" available front. Spitballing could be the word; I'd prefer flexibility. Original goal stands but I have limited experience here. I could throw something together solo but I'd prefer to maximize the available space. I have plenty of money so I could buy different subs, provided there is a reasonable argument but I'd prefer to use 3 of the V122 CW 12" subs that I started with. Amp is easily upgradable, lets not get bogged down on it :p
  11. Cold Air intakes have been well proven to do nearly nothing. Claims that they increase HP, MPG, reduce wear, and lower engine temps, are all false. The only thing they do is make a nice "whoosh" noise when getting on it. You can find YouTube videos where they do back to back dyno runs. If you just want it. Make it from PVC pipe and buy a cone filter.
  12. Top firing with 1 or more ports facing the front or rear of the vehicle. I just want the most subwoofer I can get in a enclosure of that size. I'd prefer 3 12's but if that doesn't work. I could do two 15's or one 18.
  13. So no chance of having a top firing sub with the amount of space I have? Lets for a second say I'm dead set on having a top firing enclosure. What Equipment would be recommended to accomplish that? Would a single 15' or single 18' be better? I don't have a budget. I can spend as much or as little as I want. I just don't want to change amps. No risk, no reward.
  14. That looks simple enough. Yes the whole setup is low buck mainstream garbage. The next build will be with quality equipment. I want to get my feet wet with this build as I get more comfortable with car audio. Sure I could buy a high quality Cerwin Vega - Stroker Pro with a Crescendo amp but I'm trying to do something a little different here. Its hard for me. lol I agree with ya but lets not over exaggerate. This build isn't entering any competitions, demos, or will ever see more then 30 minutes of use at a time. Variables dictate what one can get away with, "pay now or pay later" isn't always the end all be all.
  15. I like to live dangerously. Just messing. Shouldn't be a worry with this setup cause it isn't getting demo'd, I'm not competing, and I only ever drive 10-15 minutes at a time. Well... That's good to know! After a 30 minute jam session, the DB14 unit was barely warm to the touch.. Haven't used a IR temp gun on it yet though so that's subjective. I have no loyalties to Rockville. I saw these on amazon for cheap and decided I wanted to try something new. My personality leads me to over do everything, it was INCREDIBLY hard for me to buy these cheap POS. That's why I don't want to get rid of them. I'm going against everything I do in RL by using these amps. This is good for me.
