It relieves a lot of headaches such as saving yourself the wild FR response of a stock head unit (with some having peaks of +5dBs) or trying to figure out your factory HU DSP filters and settings.

What I mean in my statement in "wala naman masyado improvement in sound" is that most head units measure the same. What you buy them for are their features which, if competing, usually means for their equalizer tuning, time alignment, and other mumbo jumbo stuff.

If somebody keeps on insisting that more expensive head units measure better, I'll throw you Erin's measurements: Why does a 45,000php Pioneer P99RS measure the same as a 20,000php phased-out Pioneer 800PRS? You can't even hear or perceive a THD% increase of 0.1%.. what more of 0.00x%? Don't take the BS about the advantages of a "copper plated chassis" or something.



It's pretty hard to measure higher volume with no distortion. This is because most head units simply throw out 22W RMS regardless of whether it's a 3,000php Pioneer or a 40,000php Pioneer. If your music and driver is demanding 30W of RMS power from you, kahit ano gawin mo, you'll be distorting when all you can do is 22W THD>1%. If you have fixed power and you want to reach a higher volume, get the most sensitive speakers you can find.

There are people who claim that head units sound "cold" or "warm" with some even describing the sounds with flowery words such as "extended highs, deep bass, warm vocals but isn't holographic in imaging". But do you think they can accurately guess which head unit is in a vehicle when they're blindfolded? Ha, I have better chances in playing the Mega Lotto.

This is the reason why I used to joke around people that I should paste a McIntosh sticker sa kotse ko.. just for some magical pixie dust for them to say "woah" and tataas yun sound perception quality nila.. by a lot. And those are all benefits gained from... a sticker.
all I'm saying is there are head units that can go farther with no distortion. that for me can deliver more clarity. If you insist na wala, edi wala.
