Python Alarm System

Well I got an alarm system installed on my car today and it is really nice. But to me it sounds like my audio system sounds a little diffrent..I don't know,not hitting as hard I guess. No one else can tell and maybe I'm just being too picky about it. But is there any way at all that an alarm system can interfere with the cars audio quality?? I know it's a goofy question but I think I will feel better about it If I get someone elses thoughts.

Thanks again guys,

And it was done at circuitcity(Pro install)

its not likely - unless the guy who was installing your alarm played with your stereo..

did they possibly disconnect your battery and reset some equalization settings in your stereo?

well i cant seem to edit my post, but i wanted to add they may have reset your clock but i seriously doubt they would go back and reset all your sound settings

Hmm, I checked the settings and everything is still set the same so he didn't unhook the battery. When I did take my car to the shop my sound system was off. When I started it up the stero came on. Now I'm thinking that my speakers are blown but If that was the case no sound would come out at all or it would be muffled to the point where it's realllly bad..right? It just sounds diffrent but since no one else notices it I guess I'll just leave it alone. I just wanted to make sure that the alarm system itself didn't do anything. Thanks again. :-)
