Well, here's the strange thing. I recently "upgraded" my OEM radio/CD unit with a 2 DIN DVD/GPS HU (Motevo) and though I am delighted to have gained sat-nav, bluetooth streaming/phone & a host of others, I was very disappointed that the sound coming out from the stock speakers in my car (4 door speakers) sounded worse than the OEM unit.

Now, I know I have 2 choices or 3 (LOL), first is to of coz get an amp & 2nd is to change the speakers. I don't want to go the amp route yet so I thought a speaker upgrade would suffice for the moment. Or 3rd, I could ditch the new HU & re-install the OEM unit (LOL). The new HU is quoted at 4X50w and I am completely bonkers with all these numbers so it make no sense to me.

All I want is a clearer and slightly punchier sound so my question to all you sifus out there is, will a speaker upgrade be sufficient to give me that? And why is it that changing to this new HU gives me lousier sound quality?

Thanks in advance for any feedback.

Yes, it's plug n play but the SQ produced by the HU is worse than the original HU.

Err..then can you please explain in plain english without going into all the ajinomoto stuff. 

Is there a possibility that the OEM speakers are matched to the OEM HU thus producing reasonable SQ? Or is this just my imagination? 

Why I say this is because after days with the new HU and tweaking whatever settings this HU have, I've noticed that the new HU is "begging" for a better speaker. Or is this my imagination again? Looks like some new speakers are on the way.

I cant brain you my fren. I am just asking whether there's such a possibility
