CD's with weak sound vs. CD's with powerful vs. speaker life/blowing speakers

Hey all,

Completely new and plan to have an audio system soon, but I have one nagging question to which I cannot find an answer anywhere..

Right now I have a stock 6-disc changer and a stock 7-speaker audio system w/ subwoofer in a 2007 Honda Pilot SUV.

The situation:

I burned some CD's using iTunes with "Sound Check" on, which normalizes volume to roughly the same level.

When I play these CD's, I generally have to have the volume around 30 to hear the music at good jamming level. I don't blare it.

Normally CD's are around the same volume at about 20, without sound check.

The question:

If I have a really crappy quality CD where I have to pump the volume up to, say, 30 to hear it well, does this increase the risk of blowing my speakers vs. playing a CD that, at volume 20 sounds exactly as loud?

Or is it only the actual audio level that matters and NOT the "volume number" displayed on the stock head unit? I wasn't sure if increasing volume = increasing wattage pumped to the speaker; I guess that's my primary concern.

TL;DR/short version: Will low-volume CD's where I have to turn up the volume much higher (e.g. volume level ~30+) than normal (which is ~20ish) in order to hear well increase the chance of blown speakers? Or is it only the volume actually coming out of the speakers that matters and not the volume number on the head unit?

 
Its all about the volume that you hear which correlates to wattage. If you play a track that has no audio you will not overdrive a speaker even with the volume turned way up unless you have A LOT of background noise.

The volume you hear is what you care about. You can always buy a 20$ voltmeter to check the wattage from the amp.

P (wattage) = Voltage^2 / Resistance of speakers

My guess is the dash speakers are more sensitive plus they're getting a boost from being closer. Maybe a cheap L-Pad to dial the dash speakers down.
