I don't know. Whatever sounds musical for metal. I did 32hertz and it lacked some of the kick drum. So now I am trying 34.
If you listen to only rap. It is easy. But if you listen to more than that. It is hard.

tuning frequency is only part of the equation, the bandwidth of the chose enclosure design also has a big role, also the way the car loads can change the effective tuning quite a bit.
there is a lot more to it than just where you tune...
that being said, i love a nice flat response curve.

A little tip for anyone who insists on using vented alignments for "musical or metal" (because you should be using sealed alignments) - group delay is what makes or breaks the sound you're after. Stop tuning high. The only way to even approach the sound of a sealed enclosure while using a vented one is to tune very low so that group delay stays below 10ms in the pass band, or at least down to approximately 30hz. You effectively end up with a frequency response curve very similar to a sealed alignment but with the power handling and output approaching that of a conventional vented alignment, all while sounding very musical. Again, stop tuning high if you want musical. Otherwise you suffer the sluggish, muddy behavior that smears your leading edge transient attacks that are in between those fast double bass pedals, among the many other tight and fast effects found in lots of "music". Having an amplifier that can cope with this alignment will also make a difference.

29, 33 sounds good too.

You're going to want more of a voltage source type amplifier but still capable of delivering current if/when necessary. A good amount of power with a good slew rate (for transients) and a decent damping factor as it will pretty much be up to the amplifier to control the driver while you're not playing around tuning.
