First car stereo system, help please
This will be my first car stereo system and I have to admit that I'm
pretty much clueless, I have been working my butt off researching all over the internet I have been looking at these two particular head units Kenwood KDC-X591 Pioneer DEG-P5900I When I was comparing these two I realized that the pioneer only have a signal to noise ratio of 94 dB where the Kenwood has a signal to noise ratio of 110 dB Is there really going to be an audible difference between the two? Also, I was looking at Alpine decks but I noticed they only have 18w RMS, is there going to be a big difference in sound quality and clarity between 18 and 22w RMS? Should I make sure the head unit has 4V pre amp out as opposed to 2.5V? Or does it really not make a difference I'm looking at getting Alpine type R (300w peak power) speakers, are they any good? And what head unit would go best with them? Help would be much appreciated, |

For the most part , you should forget about these ratings. in the old 8 track cassette tape world, SN was very important. Is there really going to be an audible difference between the two? Also, I was looking at Alpine decks but I noticed they only have 18w RMS, is there going to be a big difference in sound quality and clarity between 18 and 22w RMS? Forget about it. They all have about the same power. Only special units that have auxiliary power supplies can get over 20 watts. Should I make sure the head unit has 4V pre amp out as opposed to 2.5V? Or does it really not make a difference 4 volts is nice, and I would think all units would have that capibility by now. greg I'm looking at getting Alpine type R (300w peak power) speakers, are they any good?

No, very few headunits reach their full rated potential without distortion. Zak;674576 Wrote: Should I make sure the head unit has 4V pre amp out as opposed to 2.5V? Another one to argue, but a higher voltage is better to avoid noise and distortion in the simplest of terms. I say go with 4v to be safe, most amps accept this. You can have higher voltages but it is not always needed, and sometimes does not work well. Zak;674576 Wrote: I'm looking at getting Alpine type R (300w peak power) speakers, are they any good? I was guessing at first you were talking about subwoofers here, but I'm not sure, as I think some of there comps and what not has a rms rating of 150w. You didn't mention an amp, so I'm guessing you were talking about components or some similar speakers. You may to consider a small amp for this, it will be much more clear and clean than powering off the headunit.

And what head unit would go best with them? Help would be much appreciated, When you are looking for head units, I suggest do not put too much emphasizes on specs, especially the power of the head unit. A head unit is best used as a pre-amp to an external amplifier (4-channel, 2- channel)... Even if the head unit says it can get 26 watts RMS per speaker, it will probably only pump out 18 watts without distortion because of various factors, including small power factory wires. Signal to noise ratio... don't put too much emphasis on this either. Just because one head unit has a 120 dB SN ratio, and another one has a 90 dB SN ratio, does not mean that the 120 dB SN ratio head unit sounds better. In actuality, the 90 dB head unit might have better quality than the 120 dB one. When you are looking for head units, you need to ask around to see what brand of head units have the best sound quality. And another thing is, what all do you want on your head unit? Compatibility for satellite radio, hd radio? Number of pre amp connections, does it look cool, does it play mp3 aac wma, is it reliable, does it have an internal hard drive, etc... Have fun |
