Hey, can anybody give me some advice on fine tuning the power on my amp? I have a JBL GTO 75.2? something along those lines.

On the amp there are dials to adjust crossover, freq response and bass boost. Bass boost I guess is pretty explanitory of course.

I upped them all a bit once and the bass became very thuddy and was too violent at even the tamest of beats on songs so I moved the dials back to their middle positions apart from bass boost thats upped slightly.

I just wanna know exactly what crossover and frequency response does. Ive got a small idea but not sure of the exact use.

The problem is to get it right I have to keep closing the boot up, getting in the car, turning on the battery and playing a song because the sound is totally different in an open car to when its shut and I wanna tune it for me sitting in the car while driving so it takes ages to do any tweaking .
