    Yes i see exactly what you are saying
    (hence why my brain hurt from the math...)

    The amp works slightly differently with its amperage ..etc

    I dont rember exactly now...but if i can find the book i was reading about it ill post further.

    Its becasue of this that normal headunits cannot usualy produce over 20 watts RMS...something with the pull and ground....

    Damn it i need to find that book now...

    Well... yeh. I think the amp was also way too hot when I had the gain up.

    But thats true if the sub over works i guess it could pop the fuse...
    Yeh... the sub is a pioneer. Paper cone IIRC. Its old... stock from my car which came with the lexus "premium" sound system (8" sub, and 4 4" speakers).

    It's the way you connect the sub............

    In this way it's 4 Ohm

    It really makes a difference
    ......The sub used was 4 Ohm ofcourse.......

    Note above he is useing 2 ohm subs.

    With 4 ohm subs it would be 8, 4, and 4.

    EDIT: It shoudl be 8ohms in series (first pic) 2 ohms (not 4 like i accidentally posted) in parallel and 4 with one sub straight up.

    also note it works the same way when wiring dual voice coils on a single sub.

    I mean the seperate channels are charged for it(don't know how to say it in English)
    4 Ohm + 4 Ohm paralel = 2 Ohm that makes 1 Ohm for each channel

    Acually, these subs are 4ohm, they are just bridged on the amp, making a single 4ohm sub a resistance of 2ohms.
