I am not an electrical engineer by any means so go easy on me here. I am simply experimenting with a speaker amplifier.
My situation: I have a Clarion xc1410 4-channel amplifier with a 10k input resistance that is non-bridgeable. They are powering two 4 ohm speakers. The amp is capable up to 2 ohms.
My goal: I want to bridge the amp to create 2 channels producing twice the power. My understanding is if I invert the input signal on 2 channels I can bridge those channels with the non-inverted channels.
My setup: I have a couple TI TL071 op amps for my inverting setup.
My Question: I'm not 100% sure what resistors to use as my input resistor and my feedback resistor to match this ideally with my 10k input resistance on the Clarion amp. If I use 10k resistors for both will that suffice or should I use 5k resistors as they add up to 10k to align with my Clarion input resistance? Am I even on the right track? This is what my test circuit looks like:http://www.learningaboutelectronics.com/images/Inverting-op-amp-circuit-breadboard-schematic.png
As I said I am just a hobbyist, not an electrical engineer so this might seem like child's play to you but any genuine help will be greatly appreciated!
Also, if you have a simpler, easier way of doing this (aside from just buying a bridgable amp) let me know too!
