Autotuba loaded with a JBL GTO804

[Michael Ewald Hansen]

Hey guys

Sooo, my addiction to BF cabs has gotten the better of me and I have several projects underway.. I've ordered an MCM 55-2421 which is going to be in a T18 for a HT but i've also ordered a few stuff as I want some sound in my car! So today this puppy shipped in for an Autotuba:





However, I do have a few questions as I know absolutely nothing about audio in a car!

1. How much sensitivity will I lose by building a 12" wide cab with 11" internal width - I have a Citroen C1 and the boot is no more than 31cm deep so I cant fit anymore..
2. I picked up a: http://www.monacor.dk/produkter/bilster ... nr/142790/ and will be running it 3 channel (4 channel amp) with 2 channels bridged to get decent output from the amp to the sub (120Wrms).. The amp has built in adjustable LP and HP filters..
3. What kind of speakers would I want to put in the rear? Unfortunately I cant fit 2 DR200 in the back - Sooo, what do go with?

Building a cardboard mockup to figure out how narrow I need to go to make the sub fit.. Think I might need to go 9" internally.. Would that completely compromise the design?

Quite a driver isn't it? Have fun with your build, and please post on how good the gasket on it is, as you will probably get to that step before I do.

Hehe, yea I like it.. It feels very sturdy!

Dont think ill start building in another week or 2.. Or well, might squeeze in a bit of building next week.. Ill remember to post how I find the gasket - did notice it being very rigid!

I'm thinking my mini van is a little bigger than the Citroen C1. ha I put two 18" wide AT's in it when I don't have to haul the p.a. When I do have a load, I have to put that putrid 10" JL behind the front seat for "some" hint of bass. Here's some pics on the subject. http://s1081.photobucket.com/albums/j34 ... a%20Build/
And oh yeah.... the bass is ridiculously stupid! You're gonna love one in a smaller car!

I'd actually be amazed that you could fit anything in a C1...

For our American buddies, this is a picture of the amount of room he's got to play with:


Yes, one of the rear seats is folded down to fit 3 hats, a pair of shoes and an umbrella.

Haha, yea I was wondering if the americans have even seen a Citroen C1 when I saw Spoon comparing it to a Minivan.. Its more of a shopping cart with seats than a minivan..

Actually, here is a nice picture without any stuff in the boot.. Its SMALL! - about 35 inches wide, 12 inches deep and 18 inches high.. But I could fit an autotuba if i make it 10,5/11 inches wide - however, nobody really seems to know the answer, except Bill ofcourse




And BTW! For the price of this puny little car here in Denmark, I could buy a Ford Mustang convertible in the US!

[88h88]

Ha, I used to work for Bang & Olufsen so I'm well aware of the price of stuff in Denmark.

Needs moar update...Could you fit a T18?

[Spoon]

Yeah Phaedras, I knew your car was small. I was joking.

[Michael Ewald Hansen]

Sooooo, I started building yesterday - pictures will come later today!

However, I wouldnt be able to fit a T18 as the height of the boot is only 15-16 inches.. But i'm building the AT with inner panels exactly 10 inches wide..

Just thought you mistook it for another car Spoon

[Michael Ewald Hansen]

Started building.. Its pretty damn cold around here these days and unfortunately, i need to do most of my building outside.. However, its not so bad wearing 2 sweaters and a decent jacket..

Progress after day one:



Day two was very productive, even though the cold was worse I picked up a great pace and made no dumb mistakes which could slow things down.. Panels coming along nice with the new mini tablesaw that I got for free alone with a fast panel jig I made for smaller cuts (15" wide)

I love the simplicity of using scrap ply to hold things together - makes it easier to do more panels while not screwing up anything.. I dont have a lot of days to build, so when I take a lot of hours out of my schedule I want to be very productive..

Progress on day two:

[Michael Ewald Hansen]

Oh and I absolutely love my new Ryobi cordless drill - so far, its been a HUGE upgrade, from using an old powerdrill.. Its has been running for 2 days now, drilling and screwing a lot and shows no sign of powerloss - excellent battery!

Can definately recommend buying a good cordless power drill!

[bassmonster]

Nice build, pretty much done in two days! How easy is it? I could build one from the scrap ply of my TT...

[Tom Smit]

@Phaedras-are you glueing up in the cold? How is the glue holding up? Pretty quick build, though.

@bassmonster-AT is easier than a TT in my opinion(built both at 16" wide total)
