I'll check them out. I did find a post on an F150 forum where a guy built a box for 4 6.5s. He said "Box is 53 wide, front height is 10" back height is 6.5" 12" deep." to give an idea of the dimensions that will work. Again, the biggest thing I'd need help with is the port. Not sure what the best way to do it would be. I'd prefer a slot port. But, a round one might be easier/better.SSA did a build log where they put I think 3 of their F8L’s in a ported box under the seat of a newer model F-150 so you can draw some ideas from their build.
So, based on their build thread, I've come up with dimensions that I think will work. It's basically a slightly shrunken down version if their box. Which I think should be OK since I'm using one less driver. I'm just not sure how to handle the port. Ideally, I'd like to have a slot port on the front of the box. But, I'm unsure how to calculate the size of the port. The dimensions are width - 48", front height - 9”, back height - 6", and depth 11". I'm thinking a port that's 2.5-3 inches wide would be good, but how long?SSA did a build log where they put I think 3 of their F8L’s in a ported box under the seat of a newer model F-150 so you can draw some ideas from their build.
Thanks Shredder. That makes total sense. In playing around with some calculators online, it looks like the box will be a littl over 1.5 cubic feet (haven't factored bracing in yet - I'm thinking a coupe window braces will be good). Looks like a 3" wide port with average height of 6 19/33" about 28 1/4" length will put me right at 33 Hz, which is what my last box of as tuned to. The amp that I'm pushing them with is the SoundCubed 1250. Does the math check out? I'm not sure how accurate this particular calculator is? I've got some room to go wider on the box if I need more airspace.As far as port area goes it depends on volume/power.
And for configuration I'd load the port towards the door as well subs forward.
Configured like that you'll have a much easier time keeping the port area uniform thruout the entire length of the port vs a front firing port in an underseat box where a janky bend would be necessary if using a slot.
Good call. I had that same thought when I was mocking it up to get the port dimensions. I'm pretty sure it'll be OK, but I'll double check. The e8s are pretty shallow and if needed, I'll reposition them to be clear if the front wall of the port. Out of curiosity, what's the minimum distance needed between the back of the sub and a side of the box or port?Without doing all the calculations and doing the design it looks about right.
One thing to keep in mind is the magnet clearance, I always check by doing something like this quick and dirty.
* this is not for your subs... only an example*
I've had to rake the baffle to get magnet clearance before so keep that in mind.
Glad you got me to look at this, because the subs would not fit in the box that I designed. So, back to the drawing board a bit. I'm thinking my best options will be either going with some 6.5"s (hoping I can squeeze 4 in the space i have) or reconfiguring the box to be downfiring/upfiring (not preferred, but not without some benefits). What would y'all do?Id be more worried about height and side magnet clearance.
Positioning on the baffle and/or raking the baffle can add clearance there if needed.
As far as depth clearance goes I keep it to .75" minimum.
That's why I mentioned possible clearance issues.Glad you got me to look at this, because the subs would not fit in the box that I designed. So, back to the drawing board a bit.
