I did some tests today to see what the problem was and I came to the following conclusion:

- overall the system sounds good, quite loud, except the tweeters. There is a chance that the tweeters I bought are faulty.
- I replaced the front left and right tweeters of this system with the 2 tweeters from the Hertz Cento Pro system that I own and I must say that things are different now. The tweeters complements the mids emitted by the woofers in the doors which are no longer so obvious now, that the tweeters sound right, and the subwoofer does it's job.

I am currently studying the market to see what tweeters I can order to replace those of this system, and finally I hope to declare myself satisfied with the sound obtained after installing this system.

I still don't know what to do with the faulty Philips tweeters... to repair them or not...that is the question :))

I will make a video with the installation of the system and the sound obtained, which I will upload to YouTube and I will put the link here.

Hi again!
So, after a long period of staying inside (Covid Pandemia), i managed to almost finish the setup. So far, I am still using my MAC Audio subwoofer (I don't have the OEM Philips Subwoofer), and the OEM tweeter (2 Ask and 2 Harman). The Philips tweeters are still at the shop waiting to be repaired. So far, I have to admit, that the system sounds quite good! It sounds very clear, the bass sound good. Thank you again for all your help so far, and I hope everyone is ok!
Have a great weekend!
