What does 145 DB's feel like?

[prochobo 10+ year member]

It is hard to listen to a whole song at 144.3 DB..

Not for me //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

Look at it this way being right near a airplane's engine is rated at i think like 140-150dbs. So its loud

That's using the weighted "A" scale. 140dBA is much louder than 140dB at a single subbass frequency.

don't worry about it. Just run and get a starting point.
The lower the note, the more physical stuff you see. When I do a full power sweep: at higher frequencies, mirrors and eyeballs dance, as it come down the side mirrors shake, toll-tag falls off, front window seal starts to flex, then nearer the low notes..the whole car threatens to self-destruct with body flexing window movement, you can't breathe, etc.

pretty much all of what he said.

I do 146.6 on a TL with my daily driver, and it's not loud enough. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif I like it, 'cause it tickles. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

youll get used to just about every pressure to about 155. then, it takes AWHILE for you to say "thats not loud."

but then, however, youre starting to really, really go deaf. for real.the first +140db system i ever heard was fukudas blazer, around 1987.

..wonder if i can shut off my 4 channel from my HU??

You can easily put an in-line switch on your remote or power cable to the 4ch amp. This way you can turn it off when you go get metered. Thats what i've done to my 4ch amp. This way my sub amp gets full power. //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
