This might sound stupid, but I haven't seen this question answered....

What would the effect be if I had a heaphone amp connected to my ipod, which is connected via something like USASPEC to my stock deck in my car?

well technically it will be louder...but unless you're at max volume on your deck and ipod and its still not loud enough, theres no point

what about sound quality?
it sounds decent since my car came w/ tweeters
