4 out of 5 eggsReplaced Car Speakers

Pros: Sound Great, replaced my old stock speakers in the rear of my car. I've owned them for a year and had no issues. I don't currently have them running off an amp (just direct to radio) but will be buying one soon. Once I have the amp installed i'll update this.

Cons: None so far

Other Thoughts: If they maintain after I install an amp and still sound perfect I'll bump the review up to 5 eggs.
