Harman Kardon amp question

I have the HiFi system. Is the Harman Kardon amp "plug and play" as a replacement for the HiFi amp? what would I need to make it work?

I currently have aftermarket rear deck speakers installed with an aftermarket sub with in built amp. I have purchased a set of HK midranges for the rear also. I want to buy the tweeters for the front and put some aftermarket speakers in the bottom of the door. Only then would I put the HK amp in.

I'm doing this in order to drive my rear deck speakers a bit harder. (40W RMS @ 4ohms but currently driven by the HiFi amp). And if i put those rear midranges and front tweeters in, to have them being driven properly, and have something a bit more "powerful" for the midbass in the bottom of the door.

Is this a good way to go/possible? Being in Australia, I'm not interested in BSW....

thanks for your response. So would plugging in a HK amp give more power to my rear deck speakers that are 4ohms currently driven at 2 because of the HiFi amp? I know the HK amp will give 3ohms to the rear deck so technically speaking they should become a bit louder?

Not really. Both amps are rated similar power. They are designed to drive very sensitive speakers like HK 2ohm paper cone.

Remember that the oem head unit's outputs are high level balanced differential signals and not line level signals. There are a few amp brands, such as JL, that handle balanced differential signals.
