I am and have been a Hifonics / Mbquart dealer for over 20 years :) the 10 series has new military spec PCB's and double the copper in the traces of any previous model amp in the line. when we tested the new amps they put out over rated specs on over 100 installed so far. the lowest reading We got at 14 volts flat on a 2010d amp was 2031 watts rms at 1 ohm reactive.
this is a quote from an EE that works for Maxxsonics correctiing someone on using incorrect math to determine power output on a D-Class amp. :
********** unfortunately you are allowing yourself to fall into the "old school" way of determining an amplifiers POTENTIAL output based on fusing. This was acceptable in the days of innefficient class a/b's, but you must understand that these amplifiers are far more efficient designs, a fuse can handle double it's rating for short periods of time, and music is transient meaning that the output constantly varies. Nothing irritates me more than looking at all of the posts on random forums about GUESSING output based on fusing.
so using old math try this and you will see it is way off on new amps:
1610d has 140 amps of fusing so,
14.4 volts x 140 amps = 2016 watts now you have to figure in efficency of the amp ( the new models are 85% efficient !!!) so multiply 2016 x .85 = 1713 watts but they really only do around 1630-1680 at a regulated 14.4 volts flat.
old AB amps used unregulated power supplies thats why the math actually worked for them.
exactly, here is a simple explanation:
Amps are how many electrons flow past a certain point per second. Volts is a measure of how much force that each electron is under. Think of water in a hose. A gallon a minute (think amps) just dribbles out if it is under low pressure (think low voltage). But if you restrict the end of the hose, letting the pressure build up, the water can have more power (like watts), even though it is still only one gallon a minute. In fact the power can grow enormous as the pressure builds, to the point that a water knife can cut a sheet of glass. In the same manner as the voltage is increased a small amount of current can turn into a lot of watts.
the old theory of volts x amps doesn't work in todays electronics because of step up transformers, Super D chips , hyper D chips ect.......
my home stereo has a 15 amp fuse so using old math it should put out:
120 volts x 15 amps = 1800 rms but it only pushes 900 rms and 2kw peak so as you can see the math actually in this case can lie and mislead you. if you use old math!
the internall circuitry changes the math and makes it non-constant and the math is based on a constant which is why it doesnt work anymore.
either way I will beat any authorized dealers price on anything Maxxsonics :) with a real warranty not a refurb replacement, and I warranty burned subs as well, who else does that?
