28 hz Tuning in Small Car

[matt_martin87 10+ year member]

With a smaller hatched car (mx3), will I benefit from tuning my box at 28 hz instead of 30? I realize most people tune no lower than 30 for mobile applications because of the transfer function. Im really looking for the loudest lows from 25hz to 40hz.

I don't think you will be able to tell a difference in just 2hz...28 or 30

Another reason I ask is because I don't own a subsonic filter yet and want to be as safe as possible.

I wouldn't say that no one tunes that low. Actually the cool thing about cabin gain is that you can tune that low without losing output. With the right sub and a low tuning you can get it to play loud and flat down to well below the audible range. Most people tune higher because they want the peaky response to give them more output and the cabin gain boosts it further. Additionally with the small enclosures and high excursion subs typically ofund in car applications, tuning low with enough port area to keep it from whistling requires a ridiculously long port and quickly becomes impractical.

^^^What he said. I prefer tuning in the upper 20's myself.

remove that stupid deck lid cover thing that pops up when u open the hatch. My friend used to have a CVR 10 in a MX on only like 300w and it rattled and made weird noises.

Tuning low like that will get that thing movin and makin all kinds of noise, and don't **** out, tune low, you wont regret it
