  2. New Wall for the GXP, 8 SA 8 v.2's need opinions

    in Subwoofers / Enclosures

    looks nice, but large. you could fit SA-10's in 9.6 cubes easy. and from the looks of it, you've got the surface area to do it as well.

    Thanks, the reason I choose the SA 8 v.2 is because of the long-throw design and sexy look of the motor.

    I really want to invert them which is why they are staggered like that, so the motors would take up the area that is free in the diamond.

    Idd make the box a bit smaller or drop the power

    Another option is 12 sa8v2 is the same box

    I've been doing heaps of research on these and most say 14sqin of port per sub at 0.6cuft on 600rms

    I'm in the same boat still trying to finalize my final design

    If you mdl it you'll find @ 34hz you'll get a higher db above 50-80hz by 1db

    If you after a flat curve for 8 of them

    Look at 3.9cuft net @ 34.2hz

    Thanks for modeling that for me, I was debating doing 12 of them which would be cool but I dont think I could make it work the way I want it to, I will have to look into the options of 8/12/16... I may send you a pm for some help if you dont mind.

    on a side note, how do you plane to fit them all in, ive got the same car but a few models up,(Walkinshaw equipped 2012 hsv E3 r8 supercharged 6.2l, 650hp) and without removing the spair tyre or losing a tone of power, due to weight, im stuck at only 2 of theis bad boys. and with only a small box ive noticed a huge drop in et times

    I gave up on the ET times for a while to suit this hobby and removed everything behind the B-pillars. Honestly, if you want some bump and keep moving in a straight line you can't go wrong with 2 of them.

  13. Wall question for a noob :P

    Just like DRC said it really depends if you need every ounce of space or not. Look at my build log and see kinda how I went about it. Build log is in sig by the way.

    I def like the way that box looks aha, esp with the big all thread bar through it ! got any numbers with it yet or not yet?

    Day 1 numbers were 148.9...a few weeks ago after some tweaks and sealing off the sides of the wall from the trunk I did a 151.8 burp. Will do a 150.3 on music.

  22. Anybody here own a Pontiac G8?

    I was lacking the extra 15k to buy a G8 when I bought my GP GXP but I have drove my uncles G8 GXP and I tell you this...if you have the money for the GT or GXP buy them! Amazing quality car...not only that but it has oodles of power. After my bolt on mods and tuning I run 298hp at the front wheels...the G8 GT and GXP spank that stock at the rear...I really wish I had more money to buy one...
