    you guys are looking at the fuse ratings wrong. something i read on fusing.

    just for future references, a good spec to look at is the fuse rating.

    40a x 5

    40 amps * 5 = 200 amps

    200 * 14.4 = 2880

    2880 * .8 (typical class D efficiency) = 2304

    hmm your close.. try this..

    I measure 12.8V, take 65% eff and my amp have two 30 amp fuse:

    30A * 2 = 60A

    60A + 1/3 = 80A (current point to blast fuse)(sinwave input-----squarewave output)

    Now we need to calculate the RMS output value ...we will use 60A value

    60A * 12.8V = 768VA

    768VA * 0.65 = 499 ...say 500Watt RMS output

    so what you're saying is that at 80 amp draw the fuses will blow and that your figuring the rms output at 12.8 volts 65% efficiency?

  20. i know this is probably impossible but lets see...

    *edit - someone just got back from transformers ^^^^ lol

    2 years of dating and after 2 weeks of fighting and your ready to call it quits? try solving the problem?

    well either way good luck with the whole still being friends thing lol. can try being honest talk to her about it and hopefully she won't get too emotional/crazy. my experience, being honest never really helps and they usually get emotional/crazy anyways. actually being honest usually screws me over more lol. that or try to get her to dump you haha.
