Crx Resonant Frequency

[loud1988honda 10+ year member]

Is there anybody who have a 88 Crx and know the cars frequency or can explain how to get it? I don't have a meter to get it that way so in need a formula or something the spl heads do for getting the frequency. I have a 15" h2 with 1500w. Any help would be great thanks. //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

Is this only for spl comps?

I believe its high 50s, low 60s

Yes for SPL only.

ive heard of CRXs peaking a little differently from car to car, but high 50s, low 60s like btnh said seems to be a good place to be.

So I'm thinking about 55hz or 60hz. I guess just trial and error is really the answer to this question. Thanks

Start the port lower at like 53ish, and then after each test, cut an inch or so off.

Remeber where you peak, and then find the tuning freq.
