i have 2 questions really
1. i have audiobahn 12" AWIS12P subs and i know i need to build the box to a certain size determined by the volume. but, i don't know what the volume should be.
2. i plan on having the subs inverted and facing towards the front of the car. i was wondering if i need to have a port in the 2 boxes for air to be released.

i am a carpenter so building them won't be a problem, but i've never built one before, and just need a little help

i know a lot of ppl here have built their own boxes and done their whole audio systems themselves on this forum, so if anyone could lend a helping hand it would be very appreciated
