not really. A headunit can not create more voltage than the 14 Volts it receives from your car without some sort of other amplification. this limits output to about 20 watts at the speaker level outputs with a 4 ohm speaker
A couple of years back Panasonic (Panasonic MXE CQ-C9800U) had some 60 RMS HU's. If you get an Alpine, you could run the Alpine Power pack@ 45 x 4 RMS, and it can be bridge to 90 x 2 RMS.
The Power Pack is small enough to be mounted near the HU.
