in what dB range?

Guys, i got a question, if you sit in your car and with all the windows down and the volume up, and you feel a pressure in your ears and, in your chest(lung) and in your neck(it feels like someone is choking you but no hard, just a bit) in what dB range probaly is that? that's the signs i feel when i sit in my car(front seats) and my causing who sat on the rear seats told me that there the pressure is more, he sometimes get a little trouble to breath, he breath ok there, but he get like a beginning sign of problem with breathing, i ask this because i don't have an SPL meter to meassure it and i don't know anyone close to me who has one, is the SPL meter of radioshack good?, thanks a lot.Shaking The Neighborhood

no the radio shack meter is no good.   call local shops and ask if they own a term-lab or audiocontrol meter that they rent out time on2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

Exactly what I was going to say stevdart.  And not only that, but it probably isn't good for ears.  You might be running into some hearing problems.That's my opinion. Take it, leave it, or correct me.

what?It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

The radioshack by me actually does have a term-lab meter that they rent on the 15 minutes. I believe that they charge like 20 bucks or something. Its pretty ridiculous for the average person but it was nice for me when I was really into the high dB levels.If your counting pennies and dimes then maybe you shouldn't be spending every penny and dime you have!!

Yeah I never had amy meter experience, The system This guy is talking about is like my old one. Now I have 600RMS feeding 2 sealed infinity perfects. I am wondering what dB those would make? like i have no idea, its in a SUV, would it be 120 130 135? i dont know where to even start guessing. Anyone have baselines, like 500RMS sealed open air car(liek SUV or hatchback) ~125dB??? Im just lookin for a complete estimate of numbers.99 Blazer LT.   Yellow Top. Big 3.
