your speaker has an rms of 35watts and a max of 180watts
your amp is a 75 watt 2 channel amp.

i guess the first question to ask for clearity is, is 75 watt 2 channel amp 75 watts per channel or total? I'm thinking that is the total. If so, it is ~37 watts per channel. That 37 plus the original 45 from the head unit would put it right about 85 watts. Would that cause those speakers an issue?
I know that is just the peak wattage, but the head unit and amp put out a pretty constant power level that is higher than the speaker's rms.

thanks for the clearity
