[quote name='munkonthehill' post='613353' date='Sep 30 2009, 10:09 PM']ok so final questions, is my amp currently delivering 200watts?
if i added a 200watt cab will i have 200watts being delivered from both amp and cab?
and finally will this have a major impact in my overall loudness and presence?[/quote]
If the amp has a max output of 200 watts or thereabout into 4 ohm, and you add an extension cab in [b]series[/b] to increase the impedance seen by the amp then the output will fall.
The whole idea of a 4 ohm combo with a series output to increase the impedance seems strange to say the least.
I'd argue that adding an extension cab to an amp that will have its output reduced is a waste of time.
