i bought my 17 yr old son a pioneer 7600 as a gift to put in his 1st car. i would like to also get him speakers but i do not know what speakers will run efficiently off the internal amp.he has a 93 honda accord ex coupe which uses 5 1/4 front and 6*9 rear speakers.he will most likly add a sub later on. i was thinking of infinity, pioneer, or alpine. thanks for any help.
