W211 E240 2004 Speaker upgrade, ohm questions
So, i am looking to upgrade my stock audio speakers(OEM not Harman Kardon) on 2004 E240 V6 W211.
Since i dont want to spend too much, and dont want to go aftermarket, i am thinking of buying 4 used Harman Kardon door speakers and 2 tweeters, which came with Logic7 installed on similar W211 and replace my OEM speakers, tweeter.
1/So i dont know if the HK speakers is direct replacement for the OEM speaker i already have?
2/Do i need to replace the AMP as well? the Becker AMP A2118704289 is about $150 more. While all 4 HK speakers and 2 tweeter are $110.
3/What is the ohm rating for OEM speakers and tweeter? I believe HK speakers and tweeter are 2 ohms
Thanks for any help.
If you do HK you really should buy the HK amp and add all the HK speakers which means doing a ton of rewiring of your car. (fiber from HU to AMP if not already in place, Speakers will need wire going to trunk instead of HU ect.)
