    I don't think they exist as a combo, but correct me if I'm wrong.

    Voltmeter's arn't very expensive, you can get them at Home Depot or Circuit City, they are around $15 for the cheap ones.

    Every auto technician or stereo freak should have a good DVM. Radio Shack , Sears, Home Depot... take your pick. Under $25.

    An oscilloscope can be had from eBay but if you don't have a clue then you're better off finding a bud who has one and knows how to use it. Too complicated to explain here.

    so if i want the proper gain adjustment...i should just take a voltmeter connect it to the speaker wires and match it up with the volt from the sub rca output of the hu?

    so if my rca voltage is 2.5v and i set the volume at 3/4 to adjust it...i should juss adjust it to 3/4 of 2.5v???

    u don't need the osciliscope if u are not gonna set up a huge system or a comp system. the simple 3/4's volume on cd player with gain turned all the way down then turn up the gain until it starts to distort then back it off about 1/8 of a turn.

    i dont know how the sound of subs distorting sounds like :p
    my headunit sets the lpf crossover at 80hz so how does distortion on a sub sound from below there?

    it sounds bad with the 1/8th turn down takes into account for a royal bad distort of a clip usually...aka woofers pop

    at the point it gets loudest back off 1/8th turn this also compensates being able too turn your cd player volume up a lil louder than 3/4's
