Just wondering how much watts am I getting? as the thread title says "Head 450watts and Cab 300watts". I would have gotten the 300watt head but they sent the store the 450watt head instead, for the same price so : o/ So, again...how much wattage am I getting? and is this ok to run? it won't be damging in anyway to run a higher watt head or anything? to be more specific I got the UltraBass BX4500H 450W Head and the Hartke VX115 300W Cab Thanks for any help !
