I have a Sunn SGA 107 Graphic Amplifier (100 watts @ 4 ohms). I just recently picked up a hand crafted 1x12" cabinet from Craiglist. It can handle 300 watts at 4 ohms. (The seller was not the builder, but he told me that the cab could be switched to 8 ohms quite simply in a matter of minutes). While my Sunn is intended to be used primarily as a power/ slave amp, it has a 7 band EQ and provides me with great tone, so I have it hooked up to the cab, and use this as a standalone rig. While the tone is great, it is lacking in volume. The cab's seller played his 200 watt Hartke through the cab while I was there and it was SIGNIFICANTLY louder than my Sunn. This brings me to my question: Is there a way to incorporate a second power amp into my rig as a means of providing more power to the speaker, and achieving louder volume? There is a Traynor PM 100 power amp on Craigslist. It has 2 inputs, 2 outputs, and a volume knob. Nothing else. It provides 100 watts at 4 ohms. Is there a way to hook up my Sunn + this traynor and send the signal INTO ONE CABINET in a way that will provide me with more power/ volume that what I have currently? If so, will the signal that the amp receives be 200 watts at 8 ohms, or what? Help would be greatly appreciated!!!
