I'm talking specifically Asian amps which tend to be sturdier than the Brazilian amps. Quality (Asian) amps can take a bit of clipping. Years ago there was a popular guy in car audio (Totoro/Eric Chan) that recommended clipping and even offered a audio file with clipped signal to assist setting the amp with clipping. That was a long time ago and power wasn't as cheap and dynamic compression wasn't as popular and clipping the original track wasn't a common practice.So is there even any point to rebassed music? And for all these regular clipped songs, is than enough to damage anything before the clip light on the amp presents?
If you're going to play rebassed music (which I'm unfamiliar with), I'd set my amp not clip with a 0db sine wave and keep in mind you can fry coils if you aren't careful with your volume knob, boost settings, etc. If you play a bass heavy track full tilt, you're probably going to be okay, you play bass heavy tracks full tilt for 2 hours straight and you're probably going to fry a coil. I assume you have a ported enclosure, if not you might consider porting as a way to pick up some free bass. If you're looking for maximum bass impact I'd tune in the 35-40hz range as long as you have a SSF that can go that high. Hopefully the sub has a healthy amount of xmech if you're going to tune high. 35hz is common middle ground to tune at. Maybe you just need a bigger or more powerful sub to satisfy your hunger for bass. You could try a 6th order bandpass, although I'm not a fan of the way they sound and the margins for error get really tight with a 6th order.
Personally, I don't get rebassed music. Most car audio systems are 6-12db louder on the substage (vs the front stage). Now you're taking a bass heavy track and adding yet another 3-6db of bass.
