i need help choosing best single din radio to replace my OEM radio. which name brand should I get? and I still have factory speakers and no Amp. maybe ill eventually buy some speakers also but I dont want to use no Amp. plz help

Anything with 4.5 volt preouts or higher
Cea 2006 compliant
Alpine or kenwood

what you mean 4.5 pre outputs or higher and what speakers? and Alpine or Kenwood speakers or radio?

The higher the voltage for the pre out, the cleaner the music will sound.
The sky is the limit with speakers, you can spend 30 bucks on some speakers, or 2000 bucks on a killer component set.
Crutchfield.com, look it up it will explain the basics to you

ok but are you talking about 4.5 pre out on stereo head unit or the speakers? 4.5 on what?

On the head unit, what type of sound are you after?
Something that sounds clean and loud ?
Or you wanna be heard blocks away ?

something thats clean and loud. I want a new aftermarket radio and after market speakers but I dont want a amp

go to crutchfield.com enter your car info and everything that fits your car will pop up. You can look for the same parts on ebay or bestbuy sometimes their a little less price wise or just buy from crutchfield.

Depends on how much you are willing to pay , in my opinion pioneer deh80prs for about 350 will give you the best sound quality , its audiophile components with Mosfet . I would highly recommend getting new speakers and dynamat the doors . For about 350 you will not find a better single din receiver then this one .
