Okay i have another question, i know im getting annoying but this forum is very helpful

My girlfriends civic, she has a power acoustic  LT980/2 amplifier, with 2 power acoustic subs fubr12 or sumthing like that i have it tuned it kinda sounds alright but i realized that at lower volumes the bass hits harder  and at higher volumes the bass almost decreases she has pioneer dehp4500 h/u also. Now i hear you guys talking about i have my amp tuned to 37 hz or sumthign like that and it confuses me i dont understand how i would do it i usually tune it to ear but i guess it does not work because im not happy with how it sounds now so my basic question is if anybody can help explain to me how to tune this amp correctly for both spl and s/q but mainly s/q thanks

Maybe you've confused amps with sub enclosures?  Ported boxes are tuned to certain frequencies, making the bass louder at a certain point.  Click on some of the links to the left to find out more about it.

Amps are not "tuned," vented speaker enclosures can be "tuned" so they are most effieicint at a specific frequency.  Are you talking about setting the input gain, crossover point, etc?

If your having problems with the bass at higher volumes it could be a cancellation problem. How are the subs faced? To the rear of the car, front of the car, or firing straight up?

If the bass decreases as you turn up the volume you could have reverse polarity, or be using a loudness (the bass is boosted at lower levels and the boost is defeated as you turn up the volume).  Those are two quick things to check.

Read and do what DYohn suggested first.
It could also be a box issue. Leaks, poor bracing, etc.
What is 'tuned' to 37hz? Do you have the crossover set there, what? The dials are usually labeled.
