I have a 2003 Tahoe and I’m trying to build a burp box for them I have a consistent 5996watts rms to them. 45ah Cmax 400 amp alternator two power runs voltage at 15.2-3. I have been peaking at 47-52 hz in the current two boxes I have with 152.92 and 152.26 out of either. what would be the way to go smaller then the recommended specs or larger for box what about port size small large it will be vent/vertical port not aero.
I'd bite the bullet and embrace the aero myself, size volume for your power and all but tune 6-8hz under cabin freq for big numbers.
Maybe ask someone who designs?
A properly designed aero box, designed for your power with tuning in mind may be your answer.
A 10" aero on a single 3" coiled 18 in a small SUV hit 152db plus consistently on my ranch.
It didnt need testing or any tuning. I just had to learn how to keep power around 3k (class).
Best advice is find your cabin freq and look to peak there. Then add power.
