Default Ascendant Audio Chevy Astro - THE MAYHEM
Hey guys.

Been doing this build since way back in December 2007. I thought it be about the right time to start a build thread.

Being the UK/EU Rep for Ascendant Audio, Fi Car Audio, XS Power, Powermaster, KnuKonceptz we saw it only fit to make something to challenge ourselves..

We had a bunch of ideas initially and I started on a relatively small scale of equipment which grew, grew and grew! Scott made me do something I didn't even think was possible but I'm not one to bow out of a challenge although looking back at it I would think twice about doing it again!

Went through 10-15 different designs, ported walls, clams, bandpass's etc.. nothing was looking easy.. Measured things over and over till we knew for certain what we had to play with. With the design in mind I went ahead and drew it up in Sketch and worked out the volumes etc.. along with working out the tuning points for the rear chamber. We had a nice healthy 110cuft before anything was placed inside the 50mm thick shell.. tunnel taking out around 25cuft add to that the subs, braces, subs and we have a good 6.3-6.5 per driver.

Before I begin with the pics I need to say a huge thank you to Scott @ Fi, he doesn't need any introduction the man is a legend in my eyes. Thanks also to the other people who have been involved in the creation of this build, in no particular order, Mike at CAD (SPL Dynamics), Scottie Johnson, Nick Morgan, Marshall Joyner, Edward Preston, Russ Taylor, Bill Greenberg and my other half.. who has been very understanding with the 1000s of hours spent on the build. OK enough with the Oscar winning speech..

Good work mate. I hope you've done more than that though, otherwise you'll struggle to have it ready by T17
