roscoe1129 Posted August 31, 2008 Report Share Posted August 31, 2008 i have a 7cu tuned at 35hz can i still hit good numbers? There are so many factors that play into what kind of numbers you'll hit. And 'good' is an opinion. I'd have to say, if you are happy with how your system sounds, then that would be 'good' for you.. don't worry about what numbers you'll pull --This is Footlongsam on Roscoes computer btw Quote Some people need a sympathetic pat... on the head...with my hammer Scientia est Vox "In Nomine Patris et Filii et Spiritus Sancti" DONT BE AFRAID TO USE THE SEARCH BUTTON!!!

Boon Posted August 31, 2008 Report Share Posted August 31, 2008 i have a 7cu tuned at 35hz can i still hit good numbers? Not if you're up against someone with 4cu tuned to 74hz in a Fiat Panda It's a silly question you're asking. You didn't even mention what the vehicle is. For example my Corolla peaks at 58-62hz all depending on where I put the box while my friend's Corolla 3-door peaks at 63hz, while another friend's wagon peaks at 48hz. So what good would be playing 63hz in the wagon or 48hz in the Corollas? The only way to find out is to spend a few hours with a termlab and a hacksaw... Quote 10.x volts fo' life!

alvitae Posted September 15, 2008 Report Share Posted September 15, 2008 (edited) If it was me, I'd take it to my shop after I put a sealed box in or cover the ports I did have. They have a c.d. there that each song is an seperate herz and they bump it up till it peaks on the meter.. On my 98 Ford Contour it happens to be 51 Hz. Tune from there. I think they charge 5 bucks for doing that and another 5 for a tone cd at your hertz. Edited September 19, 2008 by alvitae Quote Link to comment Share on other sites More sharing options...
psturmer Posted October 31, 2008 Report Share Posted October 31, 2008 trial and error. you can have a setup thats louder with the box tuned 20hz higher than the cars res freq on paper yet be louder than a setup tuned to 5hz below res freq of car. a general rule is to tuned 3-10hz below the cars res freq (everyone has there preference on how much lower to tune there box) on another note. in my truck getting the correct box volume is more of a factor than the tuning freq.

Neo_frog Posted October 31, 2008 Report Share Posted October 31, 2008 Well the resonant frequency of the car isn't always necessarily the peak frequency. And not only the tuning of the box, but the dimensions play a big role in how the waves travel through the car. I've had the MOJOs and they were awesome and they respond well to either music or excessive power (however you apply them). I would suggest tuning higher with the MOJO if you're going for numbers. Run a sweep on a sealed box close to the same setup as your planning (facing forward, up, backward, etc) and have it metered. Then play around with a few port designs close to that and move the box around to find what works best. There are way too many factors to just tell someone what the best setup would be.
