1 Ohm or 4 Ohm???
Hi guys, I have a small problem regarding my system (or soon to be)...I recently purchased a kaption spl1200 dual 2 ohm....now i know i should have gotten a dual 4 ohm so i can get an amp thats 2 ohm stable but thats kinda out of the question at the moment...now my options are to get an amp that is 1 ohm stable and will run around 600rms to suit the sub or i can get an amp that can run 600rms at 4 ohms and wire the sub in series right?....my question is, first of all can I do this?.....will there be any compromise in sound quality and spl??....whats the difference between running an amp at 1 ohm and at 4 ohms??? what are the advantages and disadvantages?....thanks for the input!

When running an amp at different ohm-ratings your basically dealing with the resistance for current to pass through the amp..
For example in your case running the amp at 1-ohm your amp would pull more power from the battery then at 4-ohms but also produce more heat at the same time...
I'm actually thinking of buying the same sub (also dual 2-ohm), i would say hook it up to a 2-channel amplifier [each voice coil to a separate channel] where your amp sees two separate 2-ohm loads, somewhere in the range of 200-300 watts RMS x 2 @ 2-ohms..
Good Luck

both say 600 wrms@ 1 ohm.
Phoenix Gold X600.1 - Phoenix Gold Xenon 600 Watt Mono Amplifier
or
Hifonics BXi 606 - Hifonics 1 Ch 600 Watt Brutus Amplifier
It will probably cost more for 600w @ 4 ohm
Phoenix Gold Ti600.2 - Phoenix Gold Titanium 2 Ch 600 Watt Amplifier
or
Hifonics ZXi 6006 - Hifonics 2 Ch 600 Watt Zeus Amplifier

all else equal you will loose less power in your wiring.... losses in the load stabalizing resistors may be an issue but in most cases it should be more/less relative between 1ohm and 4ohm stable amps...
all in all there isn't much difference as far as car audio applications go....

if you are running a stock electrical system, as in stock alt, and battery, then it would be more beneficial to run at 4 ohm, opposed to 1; especially if you upgrade in the future, and add more amps.
