I assume you're using the standard head unit?
If it is a standard MB unit then I would think that the speakers would definitely work but probably work better with additional amplification.
The speakers are high quality (Peerless is a good scandinavian make) but I dont think they're car audio specific which is why I would suggest the need for amplification.
To some extent it depends how loud you want to go ........ maybe try connecting them direct to the head unit and see what you think .....
Not an expert but hope this helps!

Re: Anyone good at speakers or AMPs?? Need help

Quick ebay read .. and those are 8 ohm speakers; Car speakers are always 4 ohm speakers.. and so give out twice as much volume as house speakers for the same power input.

I have driven 8 ohm speakers off a standard head unit. (transporting hi-fi). it was a decent headunit so had 25W peak power.. it worked. The Speakers are 80W RMS.. which is probably about 150W peak power .. and at 4 ohms will be nearer 300W peak power. A stock head unit will be 15W peak power so they are miss matched by about 15:1 !!

So first.. you will be compromised as the speakers are wrong.. but they will work.

1. Get an amp.. but then you really need a head unit with a low power phono output or it is wasted.

2. Get some boggo JBL's like I did.. easy to fit in front footwell stock position and the G is so loud that better quality is a waste of time; JBL GTO6527 2 cone 6.5” for £35-£21 – too noisy to notice better?

3. House speakers are probably not water proofed as much as car speakers (but those ones do look to be better than pure paper cones) .. they may die in damp weather; blown a couple of car speakers up due to standing for 3 days in soggy West Coast Scottish weather as the paper cones tore before they dried out..

4. Speakers like that really need installed in controlled and ported volumes (i.e. speaker boxes/cases) to work well.. they will work if just slammed into a panel.. but you will be throwing away 40% of the ability..

Really you need to decide what you are trying to achive and what you have to start with.. power is nothing without control.. and most car head units have no control (quality) to start with .. so it starts there.. Sony no, Blaupunkt not really, ... Alpine did do good stuff... mind you most folk end up with bogo iPod/sampled music which is compromised to start with (up the sampling rate and it does beome worth it; 192 or some such number..)

One of my other cars has Alpine head unit (last analogue amp one), Genesis 100 amp and Dynaudio component speakers .. but that would blow most budgets but engine off you get near household hi-fi..
