1. If your speaker of choice is 4 ohms you are going to loose half the power of the amp
2. The EQ is set for the speakers that are in the car so don't be surprised if the new speakers don't sound as good as you thought they would.
3. Wath the size of the magnet on the door speakers and check the tweeter mounting as the tweeter from the factory is situated in a waveguide.
Hello Infinity,
Thank you for your help.
Looks like I will probably change the head unit to a PIONEER AVH-P7850DVD unit with 50W x 8 channel. I will make use of 4 channel to bi-amp the front speakers (CDT ES-06 mid-range, DRT-21 Tweeter) with the built-in amplifier from the headunit. 2 Channel to connect to the Infinity amp for the build-in subwoofer and balance 2 channel for CDT Upstage UP-519XT tweeters on A-Pillar. You reckon it will work?
Cheers,
Eddy
