Okay, so I've been thinking about it a bit and I need some input from you wonderful and creative geniuses. Obviously my amp all together will have 8 speakers. Now what I was thinking was having the top can filled with guitar speakers, and the bottom cab was going to have 2 guitar speakers and 2 bass speakers. the 2 bass speakers would give a little extra low end to the guitar sound, and a little more tonal variety. Now oets say I wanted to play bass through my amp. Connect a bass head and just use a single cab. Now my idea is, can I have 2 input jacks to the cab, where when one Of them is plugged in it runs all 4 speakers, and when the other is plugged in, it runs just the bass speakers?
