Post Is This A Good Box?

Ok Im Going To Build A Ported Box For My Subwoofers They Are Kicker L7's. I Have Done The Math And All But I Want Someone's Opinion On How My Design Is Looking. The Lenth=37 1/4 W=19 3/4 H=14 3/4 This Is With The 3/4's Thickness Of The MDF. I Got 2.5ft3 For The Air Volume For Each Side Of The Box Without The 3/4's Thickness. Is This A Good Box For My Subs, Or Do I Need To Modify It More? The Port Is Going To Measure 2 1/2X16 1/2

All Input Is Greatly Appriciated

Re: Is This A Good Box?

Don't forget you are going to have to account for the space the port itself is going to take up. Anything that is inside the box takes up airspace and needs to be accounted for. What type of vehicle are these going in? If it's a 1st gen, then you are not going to be able to use a ported enclosure and still get the correct amount of air space. I have been through this already. If they are 10's, maybe, but not 12's. I run 2 12" L7 solobarics and there is not enough space to use a ported enclosure. I had to go with a sealed enclosure. If I went with a ported enclosure, they were not going to be able to get it in the trunk opening. The sealed enclosure still hits hard as hell, depending on the amp you have to run them. I run a Rockford Power Series X7. The sheet that came with it(the dyno sheet for amps so to speak) says the amp puts out a true 1667 watts. Most amps say they are 1000 watts, but the actual output is more like 400 true watts. That is why I NEVER use anything besides Rockford amps. The sheets that come with them are their form of a dyno sheet. It tells what the amp actually makes to the speaker, not what it simply produces before all the travel. Solobarics need a lot of power to sound good. They are not like a standard Kicker or Rockford sub that can run good on low power. They can actually be damaged by not running enough power to them. I hit 153 decibles with my system at a drag contest once. That was a good day.

Hey Charlie - can you post some pics of your stereo setup for your first gen?

Re: Is This A Good Box?

I Was Planning In Putting This Box In My Camaro But I Was Thinking If I Could Make The Box Wider Instead Of Longer And Put The Ports In The Side Of The Box Instead Of Having Them In The Front Of The Box These Are The Other Deminsions I Came Up With L=35 1/2" W=20 3/8" H=15" And I Measured And This Looked Like It Would Fit Fine In my Car Length Wise. I Talked To An Audio Guy And He Said That I Could Fit These Subs In My Car With No Problem He's Done It Before He Told Me It Didn't Matter The Length Just As Long As I Kept The Port The Same And As Long As I Got The Same Air Space Measurement. I Also Wanted To Know Does It Matter Where The Ports Are Located For The Box Or Do I Have To Run Then In The Front Of The Box?
