all of the songs I tried stayed around 5db max in the sub bass and midbass regions though. In the higher regions is where the red came in though. I have yet to try a bass mekanik track tho.
Do not adjust your amp gain w/a DMM unless the owner's manual specifically says it's OK.
You're using unregulated amps and their output will vary based on the vehicle's voltage. In addition, the Boston amp is quite under rated and clips so well you can hardly hear it over the mechanical distortion of the speaker. Compounding matters even more, the output of the amp may change when it "sees" a load.
To do things right you should really use an O-scope and set to 0db overlap (initially). Instead of a dummy load, use an old subwoofer you have laying around and/or a pair of old bookshelf speakers. Run 50/60hz sine wave thru the sub channel & 1kHz for your highs while watching what's happening on your o-scope. Once you have that set, listen to your system; do you like it? Most people do not like their systems set for 0db overlap and I'm being completely honest about that. Most people actually prefer a little 'dirt' in their music and appreciate the slight increase in average power you'll get if you do the volume @ 75% or -5dB overlap stuff.
But using a DMM is out of the question for your amps (Boston & Kicker). The Kicker clips pretty violently, so you can probably get away with setting the gains by ear. The Boston? No way, you'll need an o-scope to make sure it's set right.
I think i'm def gonna try and get my hands on DD1 like haze was telling me about and setup my mids n highs on my Boston amp with 0db overlap. My midbass and sub bass probably with -5db and then level match from my HU from there (if my bass seems to come over my mids n highs)
The disc has 0 to -15 at 40hz and 1k.. I would let you use mine but a lot of people want me to hook them up next week
