yup just one sub
im not a high end audio guy
i set my sights way lower,i wanted a little better clarity and a little bump,yes it won't bump like crazy but the avc works and i now have bass and plus i still have my bag
for high end audio i have my truck 4 kicker speakers a 10 inchfosgate sub and alpine amps behind a pioneer app radio 4
i ride my bike alot so this addition for me was perfect and it has the added value of driving my harley brothers crazy
