speaker mod help???

[mebby_boy]

ok so im replacing the umd drive with a 50mm speaker and taking out this little ones in the front. but you know how in some music the L and R speakers play different things? well if i only connect this bigger speaker to the L OR the R then some audio might be missed out. can i connect both the L and R channels to one speaker? will that work? and do any games actually use the 2 channels thing?
