A post on the ďwhat dont you like about your HLĒ got me thinking. This was the post:
However, the sound quality through the radio is another thing altogether. This is the first car Ive had with such a glaring difference between radio sound quality vs. aux/cd input sound quality. Anything through FM tends to sound muddled and flat. Sometimes, Ill notice the sound brightens up a little if I turn the car 90 degrees, which leads me to think this is an antenna problem. Itís not static crackling or anything like that, itís just muddy.
Are the sound system complaints people have related mostly to the radio signal quality?
Perhaps the signal from the other sources are slightly better, but the fact that the stock stereo is output is just around 1volt, vs other headunits that put out double or 3 to some 4volts. Aftermarket units put out closer to 4volts.
The other main issue is, regardless of source, the radio frequencies are restricted to output those that the speakers will play for a long time without agitating them. Other makes like Chevy, GM, Tesla, Lincoln and some others the stereo is full frequency, or at least much more open. Compared to Honda, the HL it still worse. (The models I have experienced). The head unit is the worst part. Some people change the speakers with some improvment , yet still restricted signal with 1volt out. The JBL maybe stronger output as its amplified, but still very muddy and sounds mono flat.
For people who dont care how it sounds, I am sure it is perfectly fine and adequate.
For people who like decent or good sound, they would care and want a solution. But many are not willing to go through it and take away their OEM looking dash, or spend the money...or they just dont spend enough time driving.
For people who are going to want 100% audiophile sound as if they are in a listening room may as well stay home and listen to their system, as its a good excuse not to upgrade either.
But if you use the car often, and you enjoy music, and you are used to good sound, and you just cant accept such low sound quality in the HL, you will want to fix this. There are the standard 2din head units that take a dash kit, while decent, you still loose the OEM smooth uniform look, and then there are Android head units that are very OEM looking. So its what you find important, and how you want to go about it. Look around the forum, there are plenty pix.
There are many threads and different levels of upgrades to address this issue, as you, many have noticed this. My wife who is not a complainer even noticed it and mentioned it to me.
