Front speaker wattage question

[Andy03]

Going to replace my front speakers and head unit. I don't want to bother with subs and amps just yet. Most headunits bang out circa 50w per channel so allowing a bit not to over work the speakers anything more than 70w rms would be unused. Furthermore a more powerful speaker would need more power to drive it and therefore may actually be quieter than a less powerful speaker. Or have I missed something

You missed something....better speakers are usually more sensitive...thus can be louder.

Also the 50w output will be peak, RMS is often quoted as around 16 - 19 watts.

Hummm this requires more research! I always assumed (silly me) that, ie 4x50 on a headunit was rms not peak.

Why advertise the number 4x17 when you can advertise the number 4x50

Actual s**t the bed, just come across this:

Can't believe I have been duped for literally 14 years about headunit output! I genuinely believed I was getting 4x50 rms from my headunits

I'd be better off just chucking any old headunit it and purchasing a modest 4 channel amp to power the upgraded speakers, hell I'll just plug my iPhone into the amp input and do away with the headunit entirely

No really as if standard unit you'll then need to splice a lone level converter in so the sound won't be as good.

Don't forget it's about quality more than power too

I know. I only have a tuner list headunit at present so I do need a new one with rca outputs and I'll be getting one with USB input.
