Nice. Just for shits and giggles, take a dB rating after you break in the speakers. hahaha.

OK, the wife wasn't home so I pulled into the garage, closed the door behind me and cranked up the tunes with the engine off and the windows up. The MAX my little hand-held db meter read was 97.7 db! That was all I could take! I wasn't detecting distortion, but I didn't want to 'blow' anything either. With the same song playing at the same volume I stepped out of the car and closed the door and took another reading about 6 feet away at the side of the car: 77.3 db, basically a 20 db drop to the outside. I guess that's good?

Now the crazy part. I put the db meter in the backseat like I did way back when. I didn't tape it down, but set on a sweatshirt so it wouldn't slide around. Rolled up the windows, turned off the radio and nailed the gas. Now I digress for a moment, the car is not as quick as before with the RAAMmat layered all over the place (2 boxes worth), two amps, subwoofer box and subwoofer, plus slightly heavier new speakers front and rear. That's kind of a bummer, but that's the trade-off for a great sounding system. Oh well. I accelerated up to about 50 mph, then pulled over so I could read the db meter...86.3 db!!! This is actually louder than before! So you don't have to go looking, the original reading was 84.7! What the heck?!? The interior sounds quieter to me so I really don't understand why it's reading higher now. Beats the Ensolite out of me! However, I don't think I would do anything different. Very strange. I'm open to anyone's guess!
