I would in the least get a headunit that has 2 SETs of preamp outputs. if your adding a sub think about getting 3 sets. As for the amp, just remember a better quality, lower wattage amp will sound better than a lower quality higher watt amp. Lastly, a bazooka tube is what it is, nothing else. Some sound ok, some don't. It all depends what your ears like. Yes it is possible to ad the bazooka to the setup you listed.
