really? physical condition and weight? is that how we are judging amps now? an amp is usually installed under the seat or the trunk, where it is out of sight 98% of times. so physical appearance doesnt matter. the amp is only dusty it seems anyways. good amps are bulky because they have components inside to give good quality sound. weight is not a measure of quality however. and comparing these old school amps to chinese crap amp shows that you have no idea what good sound is all about. This is a pretty good amp at a reasonable price.
