  1. My subs are dual 2's im running my amp at .5 ohm. I need 2 seperate boxes or they wont fit in my trunk the opening and i dont want to build in cuz them its pretty much permanent at that point.

    im buying a second 3000.1 for comps so each amp will be at 1 ohm on one alpha each for metering, i will just run one for daily.

    i guess im happy with it it just does not meter well andit makes no sence to me. it sounds way louder than my old setup was but its only 2 db more on the meter?

    lower freq's appear louder to human ear

    so a 140dB @ 40hz might sound louder than a 142 @ 60hz

  2. not sayign your wrong but i thought it was 3db for the mic to be doubled and 10 db for the human to hear doubled...

    i may be wrong but thats what ive seen/heard before...does it mention that in your link Kian? i need to read over it...looks like it could be some good info

    3db is around the range a human ear can tell its difference, but ya for human ear its 10dB to be double'd louder

    for on mic is 3 (double power or cone area to get this), do Chode69. i'm with u on this one

  3. i did a streat-beat box for a guy awhile back for 1x18", box was tuned to 35Hz for a daily driver but still put up a 148.7dB on term-lab so can still get a pretty decent spl on both. gotta watch displacement of port, when you change size of port you change net displacement for your subs because of size taken up by the port itself.

    for a straight SPL box your tuning is goign to be WAY higher for easyer notes, if playing a test-tone around the 43-48Hz range tuned with a peak around 50-58 should give you your max SPL on a note but if playing music (bass race etc.) you'll unloaded the woofer from lower freq.

    what kinda vechile is it in? do you know your car's sweet-spot for freq?
