    I'm tired so I could be off but wouldn't a 2ohm load at 70 watts deliver more power then a 4ohm load at 100 watts (P=I^2R)? Granted thats peak...RMS would be equal but I would think that would still make a difference?

    The were originally wired in parallel. So they may just be 4ohm subs.

    ...which would be a 2ohm load, and would cause it to overheat a lot, and cause it to shut off

    my sony sub amp is the same way-- it is not 2 ohm stable, but i have hooked it up for fun in 2 ohm mode for 15-30 min and then it will go into thermal protection...

    time to break out the DMM and double check.

    What is the crossover filter set to on the amp?
    Ive seen people bring amps in because it sounded like **** when the problem was because they had the gain & bass up to max & the crossover set all the way down to 20hz.

    The amp isnt a powerhouse, but Kenwood subs dont need a lot of power anyway.

    when i had the gain all the way up, i hadd the crossover set all the way down. Now that I've got very little gain, i get more out of them when I have the crossover higher at like 180-200. But still, not enough kick to really even notice

    Putting the crossover all the way down literally blocks out the bass, you never want to do that. Set the slider to LPF & put the crossover dial about in the middle (100~120hz or so), then adjust the gain setting.

    If it was loud enough but sounded bad with the gain maxed & the crossover turned completely down, raising the crossover should fix the problem & actually give you more volume. Unless you are confusing the crossover with the bass boost, which are two entirely different things.

    okay, i'll try to increase the gain until it sounds proper. If it distorts, I'm getting a new amp (which i'm leaning to do anyway).
