Things have perhaps changed since i was into ICE, I was into it in a big way 15 years back, had Alpine, Phoenix Gold, Rockford Fosgate, Monster Cable to name a few. Perspex cabinets in the boot etc, split charging system. Amazing the sound some cars can produce.
I remember going to a sound off once where this Van had such low frequencies it nearly made me sick.
Some serious money spent in this hobbie as well.
Anyhow, I was always under the impression, If a professional installer set's and builds your system into your car, they use a sound meter and there was another device, which i forget the name of, that was used as well to set the sound.
Why now do you need a 30 band EQ?
I thought if you spend good money on a system you shouldnt have to play around with the EQ. it should be set up and be left alone for the best clarity.
Like i said, I have been out of ICE for some 15 years, that's what i knew then. Things of course change, but i always thought the best way of getting sound to the speakers was to keep it the exact or as close to the way it was originally recorded on.
Please educate me on todays developments anyhow. be interested to know why EQ have come back into fashion.
cheers
