:p The stock speakers in my 1994 C180 Euro have no high fidelity at all. The 2 tweeters on the dash corners are too soft and the front door speakers, though midrange fidelity, have no highs and are quite flat. The rear door speakers and rear shelf speakers are really flat in fidelity, almost no booming bass, just a low tone in place of this and are quite disgraceful.

I want to know what type of speakers will fit my car model and how difficult it will be to replace them. Do I need a new radio or CD player or a high powered seperate amplifier to fill up the high and low frequencies?
