I upgraded speakers to Infinity reference 6.5 in all 4 spots. I left the tweeters alone.

I am happier with sound but wondered if buying a 22 RMS aftermarket receiver would make a huge difference. I would lose ONstar and XM by doing this so I want to know if anyone knows the RMS power in the factory radio.

Crutchfield did not know.

thanks

 

Which radio do you have?

 

this one http://a248.e.akamai.net/pix.crutchf...3184/radio.jpg

 

Is it the HU for the Pioneer system?

 

No just the standard radio, however it sounds like it has a little power. most factory radios dont have this much output

 

All I found was guesstimate 10 watts per channel per Crutchfield's

 

thanks for taking the time to do that, do you have a link?

I agree with Olblue. Unless its a upgraded factory system you are seeing maybe 20 watts per channel peak output. Most aftermarket headunits have 50 to 55 peak watts per channel. So yes it will be louder. Cleaner sounding, maybe. Depends on what ya buy.
