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.

Thanks for the feedback.

So are you saying that an amp is a must? My car is still brand new and though I've already void the warranty of my OEM HU, will adding an amp void more warranty especially the electrical circuits part?

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

Thanks everyone for the feedback.

I do understand the explanation by howie so everything points to the new HU for producing bad SQ. So it's a dilemma now for me between reinstalling the OEM HU or upgrading the system. Maybe I'll go for a speaker upgrade first but as I mention earlier, it'll be a strange choice considering the fact that the OEM speakers gave out good SQ with the OEM HU so it must not be so bad. Sighh....

Tried everything. Treble & bass set to maximum still not punchy enough. There's bass alright but it's just some loud boom without any err..punchiness if you know what I mean. And the treble is not sharp enough. And before you ask, yes, the loudness is switched on. EQ settings limited to pop, rock, flat, jazz & classical. Not even a choice to set manually. Sigh..I really do love all the other features of this HU but definitely not the SQ produced.

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

It's OK bro, no offense taken. Shopping around for the speakers the last 2 days.
