Here's what I'm having installed.

Keeping HU for now, will change out eventually.

Diamond Audio Hex S600s Series Up front

Diamond Audio M361i 6 1/2" Rears

Diamond Audio D7104 Amp. 100 x 4 @ 4 Ohms.

Power range for front speakers are:

Power(Watts): 20-170

Rears(Watts): 50-100

How will this sound? Will the rears be able to handle the 100 watts? Or should I drop some?

 

Knowing just the power ratings on the speakers doesn't say much. What's the frequency response and db levels on them?

Also, are those power ratings PEAK or RMS? That makes a HUGE difference...

 

Rears are peak, not so a good idea.

Fronts are RMS. I'm thinking a weaker amp.

 

The setup you are going for is some what similar to mine. I listened to the setup I am going for in another car and it sounded awesome.
