Oh, I almost forgot, be really carefull with how much space you give you feet around the pods, they need more room than you think.

Thanks again for you help Jason, according to the specs, recommended sealed box volume for the MW160 woofer I will be using is between 7.1 and 21.1L. Here is a link to the specs: http://www.dynaudio.com/eng/mobile/p.../DYN_MW160.pdf I'll try and get in touch with manufacturer re. ports etc....7.1L may be achievable since I am using the space in front of the pedals etc, but 21.1L would be impossible! |

Retaped the interior this arvo and applied another two layers of fibreglass matt (trying to minimise resin use!).

Think about 3.5 two litre bottles per panel. That's a LOT of volume. Your right, you can only get that if you wrap around. Again though, go through pedal travel with some big shoes on, make sure you have plenty of room.

Picked up the new eclipse sub today - would have liked to mount it inverted but the rollcage gets in the way so it will sit like this. 6x9 holes will be glassed over soon.
Trimmed base for kicks (again) after second two layers was applied - nice and rigid now. Once I set the mdf rings in place I'll ensure I do lots of imaginary trial runs to make sure my feet clear - I'll even make some "broom broom" sounds for special effects Not much work this weekend (going away), but will continue next week. Cheers Alan |

Have you measured that the volume is correct for the Eclipse sub in that enclosure? Contrary to popular mythology, Box A and Subwoofer B may not be compatable. The box volume must be correct for the sub or you may have much less than enjoyable results, from just poor sounding bass to woofer meltdown. You can use Kitty Litter or just plain water if everything is glassed to calculate volume. Don't forget, once the volume of the box is understood, the volume of the speaker assembly must be subtracted from that volume to equal the actual working air volume that the subwoofer sees. Usually the speaker assembly volume is somewhere in the list of sub properties.

Cheers Troy, yep I had planned to determine correct box size for the new sub (which I know is extremely important) and adjust current box to suit. Will keep you all updated.

Managed to find time after work today to position the woofer and tweeter rings via wooden dowel:
Trying to obtain best imaging is difficult without having seats in nor power to run the splits. I tried to position the tweeters to fire at opposite person's head using a long piece of dowel (didn't have a laser pointer). Its a little bit of a hope for the best situation - who knows, in the future may have to redo them once the car is up and running (we'll see) I will be making an mdf skeleton to obtain the desired shape of the outer skin (and to make sure there is adequate clearance for feet etc). Although I am interested in obtaining best possible results with the audio installation, it is my first, and also have a number of constraints (like a half finished car!) so it will not be of audiophile quality....but I'll still be happy I am sure. |

Nice work, and good advice given. I have worked with Pro audio for a while and do some mobil audio too. It does my heart good to hear someone put the focus of building a sub enclosure on matching the encloser volume to the driver being used. I have seen people go to an "Audio Shop" and get sold an enclosure that fits the space and then the shop will drop in just any driver without matching it to the box. They seem to be more focused brands and getting the most out of the customers wallet than they are getting the most out of the components being used.
Love that under dash console.
