im in fort worth texas it going to be USACi i think i will be in the stock 601-1800

ask them to play a sweep from 30-40hz... then 40-50hz... at ~half volume

this should give u a good starting point since u are tuned so low with a large box u likely wont peak over 40hz but ur car will dictate that

what kinda suv

O its in a Truck a ford 150 extended cab with seats out

[javy101]

so do they give you a cd i thought you brought your own

Play a sweep as mentioned above. If it's a termlab and they're nice you can pull up the numerical data to get your exact peak.

If you're tuned at 32hz then your box probably peaks in the car about 6hz or so above that.

Because your cabin is quite small you might get lucky and having a resonance node of your box peak within the frequency limit (is it 80hz in USACI? It is in dbdrag...) - if you have a peak at 35hz try it at 70hz as well.

The usaci I went to let you borrow a cd, Then they told me to put it on track 19. It's a sine sweep. That was my first run. the second run they told me to turn it to track 57, that was the hertz I hit best on the sweep.

Went real smooth and gave me my best number possible at that particular time I think.
