My goal is to be Brutal on Music, BUT 150+DB on music, I have the power supply and equipment so the box is my only let down

I thought 10square inches was enough?? Do I defo need double that?? Will the box still play flat??

Cant remember exact dimensions, I think its 450mm wide, 150mm high and 500mm long, but final tuning was 30HZ

Woofers are AA Mayhem 18's they require 6-6.5 cuft each, Will be looking to see exactly what I can do to increase output before I go at tearing the front baffle off

Well chaps I'm not 100% happpy with the SPL of my box, its 16.5cuft before displacement, and tuned onto 30hz, port area is 8.3in^2 per cuft, now recommended space for the subs is 6.5 per driver, and I presume port area should be 10^2inches per cuft, so should I line the entire inside of the box with an extra skin of MDF(flex is another issue except on the front baffle) this will reduce area, and also should I change the port for a larger one on the same tuning?? Any advice greatly appreciated lads

Did some small testing today, there is 1.1 DB difference between 30-45hz, so box plays good and flat, will be taking it apart though, not happy with the SPL side of it, so I'm going to reduce Box volume, strengthen it, increase port area, add 45's etc etc this should see the SPL increase

Cheers mate some testing with a TL and some videos are a must today

Maybe in Cornwall in England its chav's there's well over 100 walled cars in the UK I would think, In Ireland on the other hand, I am one of very few with this level of audio, I think I have walked into the number 3 spot of loudest in the country with this when its finished, which is a shame dude, would love to live somewhere where people dont think I am insane to have this much bass lol bass over here is a 12" bass pack of all 100 watts and 8gauge power wire, I know thats where I started off but thats the limits with people, main thing over here would be drifting and car tuning for draggin, sound is a dying breed but I hope to help build it back up

Holy shit batman Defo need to rip my box out and re build after seeing this!!

Will take a longer one just for you today

Some flex and lil hair trick And my first hair trick More vids of flex tomorrow, ran out of light today lol

lol We wont begin to talk about the postage, but long story short, second amp is in cork for the last week!! Lazy Couriers!!!! So collected second amp today, down to Rookies house to hook it up as I left my RCA's in his place, as Marko Said it burped 148 @38hz, loads of work done to the box but a hell of a lot more to do, back wall is flexing crazy so I need to put another 2 skins of MDF on, but its booming and fook me I am happy plays brutal on music which is exactly what I wanted as its not a build for numbers, but for sure there's a 153ish in there somewhere just gotta hunt it out Got some juice in the laptop, gave it one more burp @38 and: so there's defo 3 odd DB left to find some videos soon of the carnage

Welcome chap

Small video of the system there, hit 145 @39 hz sensor on the windscreen driver door open, fingers crossed second amp lands tomorrow so I can run beefy power will get more build pics up tomorrow

She booms Finally hooked it all up today, alot of tweeking to do tomorrow but its finally in and booming only off 1,700Wrms as I'm waiting on a second amp but once thats in I will be booming 5,200Wrms some pics of today, will take more and some term lab readings This power is only tickling the subs but it is nice to boom again after 3 months with no bass in my life well worth the wait, now the finishing work can begin

Another little update, Increased thickness of the bottom and top of the box today, also did some more sealing with P40 and I measured the inside dimensions of the Box so Marko can calculate the Port Length Tomorrow will see the box finished with port installed and the third and final baffle I believe Saturday is D Day for the pallet so looking forward to that big shtyle Some pics: More to come tomorrow

Looking forward to the finishing updates on this Am Seriously good work as always

Packed and ready for shipping Should have a very big update for ye over the weekend

I've been waiting since November to see those 18's believe me there will be time spent alone with these subs before the go into the car Must make a video of the mids, best front end I have ever had

Another Small Update, Went at sealing up all the joints in the car with P40 Filler, will give this a sanding down and will coat in a layer or 2 of fibreglass as well Just need to measure out my first baffle, and then cut another 2 out of it so my baffle will be 3 X18mm= 54mm thick Also have bracing in the form of 2 M12 threaded bars, not thick enoug but will do for now until I can afford something alot bigger Also squeezed another can of foam into the roof 6days until the gear ladns, its Leaving the UK on Monday :) Some pics: Bought another 2 sheets of 18mm yesterday, so now a total of 5 sheets of 18 and 1 sheet of 12 will be in the car Will have TRD Coilovers in the rear as of tomorrow too so suspension will be 100% as I will be changing arms bushing etc too Have Twin pot brakes too just waiting on Discs and Pads so I can put them on This is coming together at long last More Updates again soon

Be an interesting test, Why not have them with matching impedences?? As small a dfference in power will be, its still going to affect the scores IMO, will you be clamping them??

Any download link to that song?? haha sleeper bass tunes FTW

UPDATE TIME Finally started at this again today, did the most awkward part of it today, bringing the side walls up to where it will meet the front baffle, alot of measuring, alot of cutting, alot of re measuring, alot of throwing the measuring tape and calling it all sorts but I have the box alot nearer completion now Should see the inside of the box finished this week, if I can get my hands on resin and hardener Some pics: also got me a new back badge Defo ain't your average E10: Less than 2 weeks before equipment lands Comments and criticism welcome

Feeding that sub with 4Kw and it blew a 155?? Says alot about the build quality of these
