Why Doesn't Radio Give Good Bass?

Thank you for yet another informative answer there dezz.

As krzysiu said. FM is generally decent transmition but it's no where near as good as a digital transmition or direct conection. So you will never get as good quality which is unfortunate cause i also enjoy just listening to the radio a fair bit.

FM radio is about 2/3 of the quality of normal cd audio. The first thing you lose is the depth of the bass when you transmit in this manner. Basically the transmission leaves out bits.

All you have to do is increase the bass on your eq or whatever you use for that. Some head units can have different settings for radio and cd.

I was about to suggest that... all the head units i've come across require you to set the bass/mid/treble for radio and CD independantly.

Funnily enough, i've always found radio to be bassier than CD's!! The new HU in my Skyline is the same... just like my last car. Weird!

I think you will find its a bit like mp3, just more so. Mp3 compresses the data you cant hear, or your stereo cant produce. Radio is the same, just they keep going in to what you can here.

Technically mp3 still isnt as good as a cd, but it all comes down to the orginal recording anyway, and how good the system is at reproducing the sound.

JTS25T: Dunno man... my new Kenwood does it, and my old Kenwood in my Commodore did it. Kinda handy, cause FM radio has always been more bassier to me. (not as bad as AM radio though)

If FM radio is Frequency-Modulated, and high-pitch is in the upper range, and bass is in the lower... maybe the upper is being cut out a bit by the radio stations?

Also listening to music on air is free, and hence music quailty is also low!! Wont be your typical 128kbs..

Also since the waves travel further, the frequencies may also decrease in quailty.. not 2 sure on that..

something that i remember from uni in regards to wireless transmission.

sound (music) is a whole spectrum of frequencies. bass is the lower range frequencies, treble is high.

Frequency modulation (or AM for that matter) allows transmission of this spectrum of frequencies over a single frequency (ie what you tune your radio to).

However to transmit the whole spectrum requires infinite power (not possible) so a compromise takes place. Hence why FM doesn't sound as good as CD.

radio is up to 22khz range, whereas CD is 44khz.. which allows much more frequencies to be accurately transmitted in the spectrum. Usually that would mean that its the higher frequencies that you'd lose, so I guess there must be other explanations why you lose bass frequency... probably to do with bass requiring more power to send the lower wavelengths long distances??

Radio plays crap usually repeditive music anyhow :mellow:

They were talking about digital radio which would improve the quality, but they've been talking about that for 10 years and not much has advanced in that area.

I think some head units will try to recreate some of the bass lost in radio transmissions, which is why some headunits make the radio bassier than others... My alpine is a lot bassier on the radio than a cd, but so much so that it sounds like crap.

I also know, that all the Brisbane radio stations are shit too... especially the new morning crew on all B105, Triple M and Nova... All of them like to share with you every morning how ignorant they are and how cool it is to be a dumbshit...

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Any number of different ways. Have the coils draw sufficient current to provide contact wetting. Use different contacts in the switch, either by material or design, better suited to the low current drawn by a relay coil. Etc.

      Hmm, how does the R34 manage to have headlight relays then without getting excessive carbon buildup on the headlight switch contacts?

      Not R7R. Meant to type R&R, obviously enough.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.

      R33 headlight relay conversion?

      By joshuaho96 · Posted

      I was poking through the R34 wiring diagrams vs R33 and noticed that the R34 has proper headlight relays while the R33 is like the R32 and sends full headlight power through the headlight switch. I'm not afraid of wiring but I really would like to do this in a way that looks OEM (clipping into open positions on the OEM relay box) and also unlike the factory wiring which interlocks the high beam and low beam on the halogen series 1 GTR headlights I want to make it such that turning on the high beams keeps the low beams on as well. Any advice on how to locate the specific connectors + crimp terminals + relays I need? I was thinking one NO relay for low beams and another for combined high + low running off the factory high beam headlight connector. I don't really want to splice into a crusty old probably discontinued factory harness so fully reversible is my goal here.
