Tuning Frequency of Crown Vic or Grand Marquis

I take it you are looking for your vehicle's resonant frequency for maximum SPL?

If so, look **HERE** and prepare to READ!

ETA: If not, just go with the generic ported enclosure recommendations for your E8s.

I doubt he will get much "spl" with (4) E8s and 1200w, lol. Good subs, just not designed for that.

OP, why not just build a box 2 to 2.5ft3 net tuned in the low 30s and be done with it?

I was going to buy a pair of E8s since Woofercooker was selling them at a good price. Unfortunately, after running a single Digital Designs 1508, I was afraid I would be disappointed with a pair of E8s. As soon as work slows down, I am going to run a pair of 1508s!

I agree. Isn't the recommended enclosure size .6 cubic feet per 8 with the tuning at 30 Hz?

 
What are you doing with E8s, shouldnt you have L7s like all your other homeboys with crown vics and caprices?
I knew this was coming eventually. To the OP I would not worry about the resonant frequency too much. I would build an enclosure that is the correct air space and tuned to the recommended frequency and it will be fine.

 
Do you have any pics of your install? Very interested in how you fit 4 12's in and got 7.8 ft^3. I could only get 7 even, but thats when I had some cheap Lanzar subs.
