I have 12 of these speakers in my back seat and im being heard a realistic half a mile down the road clearly word for word I had to turn up my amps and these speakers are still sounding clear just make sure you have the proper balance for your car audio system…..tweeters for highs and subwoofers for lows…..I thought I was used to the sound until I turned up my amps now when I get out my car my ears hurt so bad that my back teeth hurt…..my hearing comes back to normal after about 30 minutes outside the car so YEA THESE R GOOD SPEAKERS
