mothra Posted November 15, 2013 Report Share Posted November 15, 2013 so i'm on my final build and decided to just get it over with. i'm going to wall my hatch with 2 18" DC Level 4 m1s. i bought all my equipment for the build already so it's just installing it. I was planning on a net 16 cubic ft box with 4 6" aero ports since I only have just over 2k of power to put on them. i keep seeing smaller enclosure sizes so no i'm thinking of a net 12 cubic ft box with 3 6" aero ports. i only have 2k worth of power to throw at the 2 of them, that's why I was thinking the larger enclosure. I'm not after numbers or hair tricks b/c i know that is just not going to happen. I just want the subs to be happy. net volume, 16 cubes with 4 6" aero ports vs net volume, 12 cubes with 3 6" aero ports both seeing the same power in a ford focus hatch. any first hand experience is greatly appreciated.

CleanSierra Posted November 15, 2013 Report Share Posted November 15, 2013 (edited) The subs don't need less port just because they are in a smaller enclosure. The cone area, tuning and Xmax doesn't change, the amount of port shouldn't either Edited November 15, 2013 by CleanSierra Quote Im not the one you want to try to troll. Just a fyi for you.

mothra Posted November 15, 2013 Author Report Share Posted November 15, 2013 I think I may have put things wrong. My question is more a vs of larger net volume vs smaller new volume. The change is port area change is mainly bc of net volume to keep port length reasonable.

n8ball2013 Posted November 15, 2013 Report Share Posted November 15, 2013 Honestly I wouldn't try to compensate for lower power. You know youll add more power later right? Would you want to rebuild because of that Quote THERE IS NO BUILD LOG! 1998 Chevy Silverado ext cab Alpine CDA-9887 4 Team Fi 15s 2 Ampere Audio TFE 8.0 2 Ampere Audio 150.4 3 Digital Designs CS6.5 component sets Dual Mechman 370XP Elite alternators inbound! 8 XS Power d3400 6 XS power d680 Second Skin Stinger Tsunami Wiring Sky High A Real Voltmeter not a piece of shit stinger.

CleanSierra Posted November 15, 2013 Report Share Posted November 15, 2013 I'd probably do a slot port rather than aero. You're crunched for space huh? If wanting to go aeros, you still may try to keep the 4 6"ports. I wouldn't sacrifice port area AND lower volume. You'd never be able to guess which one was your culprit if it sucked. I'm not saying it would suck, but don't change two variables at once, just change one. Quote Im not the one you want to try to troll. Just a fyi for you.

mothra Posted November 15, 2013 Author Report Share Posted November 15, 2013 Thanks for the input guys. I greatly appreciate it. Space is only limited by the car itself as I am walling it. Power is most likely going to stay where it's at bc I can only fit one H.O alt under the hood. I really want this to be a good all around car. I run in the high 12s but that's with no system. Once I get the system in I am changing my motor set up to hopefully stay in the low 13s still. If I can still run a low 13 sec 1/4 mile and hit high 140s I'd be the happiest guy on the planet. I am just realistic about being able to do both in a ford focus hatchback, it's just not all that reasonable.

alaskanzx5 Posted December 30, 2013 Report Share Posted December 30, 2013 not being able to fit a dual alt setup does suck. could sacrifice power setering though lol... if you want to try and still do 1/4 then go with a smaller box for less weight.
