two 18"s 4th order trunk build box help


Phaeton

Recommended Posts

So im doing a trunk build on my caddy and i was wondering about ports. i was thinking 4.1 sealed and 7 cubes ported. The graph it made in winisd seemed pretty good so i might go for it. Of course i have the best and worst car to do a build, cant fold the seat down so i need to cut holes in my rear deck for the port, so the question is should i do a regular rectangle port / slot port or areo port / pvc tubes? and how much port area? i'll provide some pictures for better understanding what im going to do.

The biggest problem I have with this, is that 4th orders may take a lot of trial and error to get right. Meaning adjusting the sizes of the ported and sealed sides, and port area. If you cut through the deck, how can you adjust port area? If this thing is built in the trunk the way you have it drawn up, how would adjust port length? You basically have one try, and if it sucks, then what?

take it all out and do it again. This isnt a very cheap hobby and hey, i get to do something i enjoy. sometimes living out in the country sucks because there is nothing to do. So i have no problem doing something like this over again 6 or 7 times lol.

How about that ported box? im guessing it wont work very well eh?
