The car when it arrived


Quick alteration to the front end




Unfortunately someone reversed into him within 2 days of owning the car So had to sort that out









The bonnet was bent like a banana so a second hand one was sourced and fitted along with dark crystal front lights etc...ill get some pics of the front end soon

Interior


Stripped


Deadened and expandy foamed






False Floor


Will update as we progress

more updates

after a long day today, all the cables have been ran...false floor has been bolted down so im glad to say, i hope, we should be at the stage to begin making the wall! But thats for next week LOL!

Todays progress...

Voltmeter test fitted...ill get some better pics up soon


The back section of the MDF roof has been expandy foamed...roof is SOLID!


Front section of the roof has been smoothed out


DIRTY floor!


Cleaned up ready to go


All cables bar the RCA's are covered in braided sleeving and will have heatshrinked ends etc


I know this is extra and gains nothing for us, but the cables are secured every 6" or less




General wiring shots;













If your wondering why we have RCA's running along the B-pillar, its due to the Epicenter going to be roof mounted...which is what this is for...





Thats all for now folks! Be sure to tune in in a few days to catch the next update LOL!

thats mint, could you please explain why that much sound deadening is better?

just to stop other sounds being heard so its only the speakers?

pingu.woods

nice work there mate

bassboy

to stop the panels from resonating at such a high frequency...when you tap a panel, the frequency of the sound it makes is relatively high pitched...by adding 1) mass and possibly 2) strength, into the panel, you can reduce flex and reduce the 'rattle' caused by flexing panels...the tap on a sound deadened panel sounds more like a thud...even if that panel moves and flexes, the sound it makes wont be very audiable...this stops the common rattling sounds you get from cars with subs in them driving down...the rattle is often so loud it overtakes the bass!!

Deadening also helps with the quality of the sound...a speaker on a solid mounting plane/baffle, will sound considerably better than one of a flimsy piece of metal...the energy that speakers use to move is really quite something

So deadening is used for 2 reasons, strength, and for dropping the resonant frequency of panels...the stronger the car chassis, the better the bass will sound...flex is kool...but it ruins low end bass

bassboy

jammerrs

ow right, thanks for that

bassboy

Quick update with this, not had the chance to work on this due to the car being needed, but managed to get some work done to it today...

First of all, subs are here

AA Chaos' 15" D2's, 800wrms, 21mm xmax each way, 27hz fs








Got the Epicenter mount ready to trim










And started glueing panels together for the start of the wall build


bassboy

RANJ

looking good

bassboy

got a bit more work done yesterday...









Bit of a tight squeeze with the depth lol...but the fit is fine....the front face is VERY tight as we didnt want to have a step in the box.

Volume wise its over 18cuft before displacements (approx 17cuft after) tuned low

Front panel will be 3 layers of 18mm MDF same with the rear...top and sides are 36mm thick...port needs to be braced yet and the box resined and matted...hopefully the FG will go on tomorrow so it can cure until monday, then back panel on, bit of work here and there, extra baffles bolted on, and the box is built

bassboy

mark

like it
wish i had the money to do this in my car

bassboy

flaring ports;







Rounded inner corners




Unfortunately progress was halted today by running out of resin, new batch will be here tomorrow so we can carry on with the FG, put the back section of the wall in, and carry on with the boot area of the build

Few better pics of the voltmeter




Tomorrow the plan will be to finish the FG, put the back section of the wall on, make the battery box, put the final layer of MDF on the front section (totalling 54mm front and 36 everywhere else), position everything in the boot, begin the cable runs and hopefully if theres enough time, work on sealing the wall in!

Good work

bassboy

some more updates today...

Box completed structually (unforunately my local suppliers didnt have any steel rods in so for now we will leave it without them, and add them later should need be)









Front baffle now 3 layers of 18mm thick


Epicenter mount put up






Dash tweeter builds done




more to come

bassboy

bassboy

Mirror base tweeter builds ready to paint and then at a later date flock




Voltmeter up and running (LOVING the resting voltage!!)




Battery tray test fitted


Battery specs


Back wall carpeted and amps mounted






more to come

bassboy

bassboy

Front of the wall is vyniled and the trim panels for it to seal the wall will be carpeted back for a bit of contrast


Car dont sit too bad considering the weight!




Thats all for now folks!

bassboy

subs are in

Forgot to update this for a while...ops! Right, the car is now playing but the wall still needs sealing off properly...We have temp side panels up but the roof still needs sealing off as the air is still going backwards...

Definately impressed with the setup...punches hard, drops low...does well for 3k of power for sure! Subs definately need more power as there is plenty more xmax to come...the alt is BIG let down to...being only 55amp we are dropping down to around 11.9v, then the protection circuits on the JBL's kick in and cuts the volume

Some wiring pics for epicenter etc









door builds











Tweeter builds
