I've had these speakers for about a year. I put them in my 2006 Sentra SERSpecV. I'm not running any amps right now, just the stock power from the JVC head unit. These speakers sound great! I didn't want anything teeth rattling, just good, solid sound. The frequency response is great, especially after I got the custom EQ on the JVC dialed in the way I wanted. Nice, supportive bass, solid mids, and sparkling highs. And the price was awesome. I couldn't be happier.
