The wire is from knukonceptz.com its a multistrand O guage it makes other O guage look like 4, box was built at 45hz its actually tuned in my tuck to 48-49hz,the box size is right at 3cuft. AQ amps are great for the money, you cant pass them up, but when I bought my AQ, DC didn't have amps yet. It looks like to me the bass knob is exactly the same on the AQ as it is for the DC???Possible same manufacturer of amps, I think so.
