Couple of options I'm looking at. Just to confirm, RMS refers to the rated wattage of a single speaker? They're sold in pairs but they don't make this stuff very clear, sorry for my ignorance haha...

If the listed RMS is for each individual speaker;

Sony XS FB163E - 45Watts - 91db Sensitivity - $59

Sony XSXB160 - 55Watts - 90 Sensitivity - $79

If the listed RMS is for the pair of speakers;

Kicker CS654 - 100 Watts - 90db - $109

Kicker KSC654 - 100Watts - 90db - $169

Cadence 60.3DS - 85watts - 93db - $129

Cadence 602.DXC - 100 Watts - 93db - $199

Thank you so much for your help!
