i think so mate. i was well into installs when i was younger. use to love spl contests and anything over 150 db was classed as feckin load.
basicly if you have a 8 ohm speaker and run it parrelell (wrong spelling) with another wiring it as + to + then negitive to (next speaker) to + then you half the ohms but still keep the power.
thats why you can get subwoofers running @ 1 ohm and still pownding out loads of bass. but you need the amp to suit.
and anything running .36 thd (total harmonic distortion)was classed as good sq.
but if im wrong im sure cully will be along shortly to put me right. lol
the lower the impedance/ohmage ends up the more power the speakers drag from the amp . . . . my quite expensive Electrovoice PA amp will work down to about 2.4 ohms but most amps will fry themselves before that . .
if you get a amp that is 2x100 watt @ 4 ohm = 200 watt.
if you get a amp that can run 2x100 @2 ohms then 400 watt.
again, get a amp that is stable @ 1 ohm and it can run 800watt.
thats if of course you run it in parrellel. ( wrong spelling). lol.
