Vvrinc: Radio Shack sells 1-ohm 10w resistors. They are a dollar or so each. What I suggest you do is buy 4 of these. This would allow you to use 2 per side to try out 0.5, 1 and 2 ohms to find a value that gets the level to your liking. Once you find the value you like, you can find a higher quality "audiograde" resistor to replace the RS parts. There are many online sites that cater to DIY audio hobbyists with high-grade electronic components.
These power resistors have relatively thick leads. You can bend the ends 2 or 3 times and put these directly in the socket currently being occupied by the metal jumpers. There's no need to solder the resistors to banana or other connectors first.
Hope this helps.
