I ran my stock speakers full-range all the time with my stock deck, and I only ever bothered to put the volume to 15 or 16 max...as that was the max volume before the deck went into distortion. I do the same now with my JVC AR 5000, except the speakers sound even cleaner (more power, cleaner power, cleaner components in the pre-amp and amp stages), however, after playing songs like "Pass the dutch" or "Salt shaker" at high volumes has spent the voice coils in at least 2 of my stockers. I'm gonna replace them with Power Acoustik XP2K or PR series 6x8's...they should match my other Power Acoustik stuff. I only ever put my new deck upto 25...above that it's actually too loud, and it starts getting into distortion at 30 or above.

The infinity speakers you bought are meant for finesse...to sound smooth/clean, and are abviously not the shallow mount variants they have. I'd get something cheap like the JBL GTO or the Power Acoustik's like me...they are affordable, fit good, and are designed to take a beating long-term.
