If you wanna represent Dual, get their preloaded bandpass box..
Is it good equipment..? Not really.
However, I've heard this little setup get decently loud back when I was in HS and people had cheap systems.
If you can snag that loaded box for like $50 or so from someone who just wants it gone (and I see that a lot, lol), I would probably say go for it.
Dual's radios though... uggg.
