Running rears off my head unit or amp?
I'm about to start my 3rd corvette install job, first C6. In my two C5z's I ran the front components and rear 5.25s C/As off my 5 channel amp. Speakers were rated at 90 RMS and the amp gave me 75 RMS so it was all good.
This set up the amp is a 60 watt RMS max per channel and the speakers are 130 RMS max. I can bridge the amp to achieve more power to the components and run the rear 5.25s off the head unit.
The question is what would you do AMP power them all or bridge to the front and rears off the head unit.
Speakers are Polk MM1s
Kenwood Head unit
Kenwood XR900-5 AMP

Copy this to your favorite media and this one The whole album is no longer available anywhere except Ebay once in a very great while, but it is called Percussive Jazz and the whole album is on Youtube. Well worth getting to test your stereo system.and creating the best soundstage possible.

Which ever way I go the rears will be in stereo not mono, I have a base system anyway and I believe only the Bose systems were wire in mono. The center channel is already unhooked.
Do you know if the rear speakers receive a full range signal from the stock amp.

I think this is what I have decided to do. I really want to give my front the power they can handle and Im thinking the rears will be fine on the 15-20 watts the headunit will provide.

Way better to over power the speakers so that the amp doesn't clip when you turn them up. If I wanted to put together a really solid system I would want at least 150w per channel going in to speakers like that, preferably more.

Not sure what speakers are 130 RMS...not that I don't believe you it just seems like all the ones I see are in the 80w range. If I wanted to put together a really solid system I would want at least 150w per channel, preferably more.
Peak Power Handling: 375 Watts per speaker. Continuous Power Handling: 125 Watts per speaker. Nominal Impedance: 4 Ohms.
This is my 3rd system I have done in a corvette but the first time I'm not going to amp the rears. The fronts I have used in the past are no longer made MB Quart Q 216s which I think were 80RMS at 2 ohms so the amps matched perfect and I was very happy with the results. If I bridge the amp I will get 150 watts per channel at 4 ohms which is a better match than the 60 max if I don't.

I've always been a fan of every speaker set having it's own amplified channel. I currently amplify my rears. They sound very crisp and clear. It helps deliver a fuller sound. The beaming from the speakers in the driver door alone is about as terrible as it gets. Having the rear speakers helps balance the sound IMO. Then again I run bi-amp'd, so I have an abundance of channels.
