carlthess40 and pzannucci,
Thank you for your response to my questions.
carlthess40,
What types of upgrades?
pzannucci,
Yes, the inputs are 1/4 inch. Does one parallel input go to the receiver's positive speaker terminal and the other goes to the negative? If so, how do I know which is which on the KP-3002 speakers? The parallel inputs on the speakers do not indicate a positive and negative terminal like other speakers I use.
Once again, thank you both for your responses.
Thanks,
Henry
