WOW you can get a KX2500.1 for less than that. Look in the classifieds and use the search.
where the hell have you seen one a kx for less than 450? plz tell me //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
KX's and ZX's, same boards, probly slightly better components used on the board of the zx, but essentially same amp. i've run a 1200.1 at 1 ohm just fine. my kx 2500.1 DOES NOT EVEN HEAT UP AT 1 OHM AFTER LONG PERIODS OF BASSING IN DAILY DRIVING. and this is off a relativly weak electrical system, i only have a 90amp alty and 2 red tops. it's efficent, and handles 1 ohm like a champ. in fact with a stong electrical i could probly squeeze a good 2700 maybe?
but back to the question a hand.....all the amps of zx and the kx before have been 1 ohm stable. IMO the 2500.1 took 1 ohm daily beter than 1200.1 but thats probly because my friends car had massive electrical dips and thatll cause osme heat. even with the heat it wasnt even that bad, not blistering hot like some amps ive flet. I vote the zx, the digital stuff is fun and all....but the zx is more practical, and you'll get more than 1500 out of it. even if you run right at 12v youll still get that 1500w, but if you keep ur volts up itll be more.
the controls on the sx seems cool. but for those subs itll sound better haveing that little extra juice for them. i mean controling the crossover and some things digitally is fun and all, but i dont see there being a huge differance in SQ, if so probly wont be much, and the extra juice will make up for it. remember thats supposed to be 1500 @ 2 ohms, with a good alty youl can squeeze more out of it. my 2500 has taken the abuse the best out of any amp in its caliber thats ive used. everythign else just heats up crazy when you daily drive it alot under rated imp. but this amp, and it's like models will give you jsut a lil more @ 1 ohm //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
