Upgraded from factory to Alpine CDE-9846, but 2loud!, what happened? speaker+heatunit mismatch? Options

i've got a '99 Toyota Celica GT. i hated not being able to play mp3 CDRW's/CDR's, so i upgraded haphazardly because i was also installing a new alarm system yesterday.

^got that installed yesterday. i didn't have a chance to demo it much last night when i picked up the vehicle... but this morning, i tried playing stuff. the unit plays all the way upto 20+ in terms of volume... but anytime i approach 4 or 5, all of my speakers are distorted. it's 16w RMS, what the heck is going on? i didn't upgrade anything else, ONLY headunit. it's just 2much power and overbearing. the speakers are distorting like crazy if i play too loudly. i can't get a clean sound, loud sound, just muddy sounds. what could be at fault?

i don't have $ to upgrade to new speakers... i just wanted the capability of mp3 playback, which it does.

In short, you are now amplifying your sound twice. Already amplified signal from headunit goes to stock amplifier and gets amplified more.

Go back to the person who installed it and say that your stock system already has an amplifier from factory and it is causing problems.
