I want to replace the front and rear speakers in my car, all 4 speakers are 6.5"
My JVC MP3 headunit is rated at 4x50, 19w RMS, 4 ohm and I've been trying to find speakers as close to that RMS as possible, since I learned it'll sound better the closer it is.
So far I've only been able to find a 3 way speaker at 30w RMS.

Now my question is this: my Skyline already has tweeters in my pillar, so would running a 3 way speaker, therefore giving me 4 front tweeters be a bad idea?

wow that really depends on the speaker... but im gonna say, in that low power range, that a coaxial speaker with 10 tweeters will probably work the same as 1.

For a skyline and all, Id like to really recommend a new Headunit, or at least a nice little amp for you. I guess I need more info.

Its not so much the speaker RMS power, but the speakers efficiency that matters, you will find this in the speck sheet for the speaker , and will read something like this. 86dB 1watt 1 meter, 89dB 1watt 1 meter, 92dB 1watt 1 meter, the higher the dB the better, higher watt speakers are normaly less efficient, [ not always]. 94

It is a new headunit though, I got it only 9 months ago.

Thanks, I'll add that to the list of things I check for.

 

yeah, about the headunit, it may work great, and be a good one, Ive just never heard anything good about JVC, in all honesty, I have actually heard people say JVC has no buisness making headunits. But I dont have experience with them, so I cannot say from experience.

This is a good link to check out.. LOTS of info, on everything I could ever think of.

I've gone ahead and got Pioneer TSG1615 twin cones for the front.


and TSG1645 2 ways for the rear.


They sound great and only took 3 1/2 hours to install.


I couldn't believe the condition of the rear speakers, the paper cone was so brittle after being in the sun for the last 10 years, and the rubber surround holding the cone to the metal frame of the speaker was totally missing for all four speakers.


Both are 130w max, 30w RMS, 92dB (1W/1m)

But I already have seperate tweeters in the front.

 

its a rear fill thing, preference really. I used to not care, then I got it balanced, and it really does sound best.

So basically, in general, more sound up front seems to sound better. Putting tweets up front helps bring that image to the front.

IE. Do you sit with your back to the band in a concert?
