didnt find too much on the topic of clipping
did a search and found a little bit of info, but i want to know if there is any audible effects of clipping. the main reason is that on hard bass hits, my subs make a weird sound. the only was i can describe it is like someone making a "P" sound in a microphone. i figure it's either clipping or my subs just extending to their limit. either way, i know it shouldn't be doing that. i'm not exactly sure how to tune my amp so that coulbe be the problem; i would like to know how to do so properly. I have a bass level control as well as external (sub amp) volume control on my head unit. then on the amp, there's a gain control and a bass boost control as well. what order and how should i adjust these levels??? thanks

That "p" sound is probably the clunk of the sub reaching it's mechanical limits.
Clipping is tough to hear at low frequencies until it gets very severe, but basically clipping is when the sine wave (all sounds are sine waves) are flat at the peaks. This happens because the output of the amp has exceeded it's maximum voltage, so it just can't go any higher. Draw a sine wave, then scalp the top of the wave off and that's a clipped signal.

To calm that down, I'd turn the bass boosts/levels/ whatever you have down. Its hard to tune a setup without actually being there, but what I'd do is start with levels set at half and bass boosts off, Bring up the level until its either where you want it or it starts breakin up/popping, then pull back about 10-20% from there. Then dial in a little bass boost to thicken up the sound. But if its popping like that, your maxing something out, likely speakers, basically what you need to do is turn it down.
