a marantz 4240 4 chanell receiver is rated at 40 watts per chanell in the 2 chanell mode. you can connect another power amp to it. if it's more than 40 watts per chanell you will use it to run the front chanell. in the back of your receiver turn the switch to 2 chanell operation. connect the front pre outs to your other amplifier. connect the rear pre outs to the front main in of your receiver. i had a 4300 with a phase linear 400 amp. the 400 powered the front chanells and the receiver powered the rear channels.
