Thanks! I should have pics of the finished sub box soon. 99% of the parts are in now and I will be able to complete the assembly and finally get the last of it installed hopefully within the next few weeks.
Work left to do: complete the assembly of sub enclosure/amp rack, sound
deaden front doors, install new speakers, install sub enclosure, tie in all connections, test and align. Around 50 hours work - maybe a little more
