Box Tuning question

[argenis69 10+ year member]

Hello, As you know I have a 02 Nissan Maxima with a 15" Fi SP4 in a 3.5 cu ft flare port box powered with a 3500 Crescendo amp(check my signature).

I would like to know what's the best frequency to tune this box to get the maximum loudest bass output with decent sq?

Thank you.

One question, I have some curiosity about how does the tuning work, the higher the louder? Or how does it work?

3.5 is a bit small for a 15.

Yes, I was trying to save trunk space.

I know you're knowledgeable but since when is 3.5 cubes too small for a 15"? 2.5 cubes is recommended for the Type R 15", and I'd have to say most 15" will work great in 3 cubes, let alone 3.5.

Loud in terms of htz isnt really relevant here...say ur car peaks at 50 and mine peaks at 40. i will lose output past 40 and you will gain the closer u get to 50.make sense?

Makes sense, but is there more or less a standard tuning frequency where the subs tend to have better output no matter the vehicle or environment?

All depends on the sub ..and type of music u listen too but id say 35 is a good middle ground..the sp4 is a low end monster and does well tuned low if i were u id bump it up to 4-4.5 cubes at 35 and you should see greater output

This is why you should have a box built around your cars cabin gain... Not all shops do it tho...

Thanks, but I need the trunk space. Does it help and make a big difference to tune it to 35 hz in the 3.5 cubic feet enclosure I already have?

I did that, I'm just curious with the tuning subject.
