Ok I have a 2023 SGS. A while back I was given a FREE a Boom Stereo HD Amp with Wire harness ( front and back ) and (4) RF speakers from a 2021 CVO. I know people are going to bash on this but it was Free. I went ahead and got the Radio Flashed by the HD Dealership. My question is will I benefit (meaning louder) if I replace JUST the RF speakers and get better aftermarket speakers (4 ohms).

 

All depends on the sensitivity and ohm rating of the speaker. But even then, you are not going to gain much because that Boom amp barely puts out any power.

 

Thank you for taking the time to respond. It seems I may have to go to an aftermarket Amp, Do you know if there is there a plug and play wire harness that will go from the OEM wire to an aftermarket Amp.

 

If it's readily available Crutchfield will have it, their customer service goes out of their way to help.
