massive power supply. can run under 1 ohm. down to 2/3 ohms. just add fans.

power hungry. feed them

im running 2 of these amps. about the alternator, in my other vehicle i have a big fat alternator and they do fine, but now they are on a factory alternator in a pathfinder, and it has been running them for about a year, and they are both at one ohm, and i bang on them all day. now they run hot, and could bang louder, but i still do well in the competitions. i do recomend a big alternator though. dont just buy two batteries. what will happen is your factory alternator will now have to charge two dead batteries. thats when you will hurt it.as for the kicker. this amp is a big bad beast. i once ran 12 12w0 12 ohm jl audios on one. yes they made 12 ohm. it beat the crap out of all of them. another way to hurt your alternator is to try to run one of these amps on some thin wire. treat this amp right and you will enjoy hours of concrete crackin, glass breakin, ear poppin, battery killin, neighbor hattin, sheet metal flexin, of course cd skippin (get an ipod), license plate loosin, wire meltin, cab heatin, massive woofer blowin, baby wakin, usac stompin, trunk latch breakin, retarded loud, chest poundin, eye waterin, dash breakin, ticket gettin, rediculis, stupid, super slammin, alternator belt throwin, awsem, rearview mirror in your lap bass. just stay out of my class please, i dont like to run up against kicker amps. it takes away my advantage. a side note. i have never got rid of a kicker amp because it didnt work. they only end up in someone else's car because that person is a piece of crap and stole one from me.

Alright y'all. If you really like the xs100 READ ON! I've had one for a little over 7 years. I've hit many high numbers in many different vehicles with this amp. I know that it is rated to go down to 1 ohm, but I ran mine on 6 12w3d2's. Y'all installers already know that ohm load, but for those of y'all who dont.....thats 2/3 ohms. I hit a 160.8.... If yo do this to your amp if it shuts down, it is not the ohm load shutting it down, it is the heat. Put massive air flow over it, and it will NOT shut down. Now imagine.....Y'all's amps birth certificates are claiming from 1400 to 16 somthing @ 1 ohm....whats it gonna throw @ 2/3?

Alot of power.

Runs super hot at 1 ohm and it hurts my ears.

Huge amp at 28 inches long. Pounded the hell out of my two 12 inch pioneers ran at 2 ohms mono. You could here me about 30 seconds before I arrived at my destination. Very underrated. Old schools amps are the best.

Goes down to 1ohm for competition and is rated low for amp class rules.

Not recommended for everyday drivers. Play this amp around town at 1ohm and you won't see your alternator around for more than 7 days. Unless you have a high output alt.

This amp is very underrated. It is rated at 50x2 watts at 4ohms stereo and bridged at 1ohm it will put out 1400 watts or more. This is a high current amplifier so added batterys are a must. The size of this amp is very large.

Very reliable, never shuts off.

If you dont know what your doing it will kill your battery and alternator!

This guy is full of it! I am running 1.3 ohms on a Orion HCCA 15 with 4 guage wiring and a 1.0 farad Lightning capacitor. I own a 97 Chevy Cavalier and have never had a problem with my battery or my alternator. The only thing i agree with is that it is hard to find speakers that wont blow. I have tried to blow the Orion and all i can get it to do is smell!

never gets too hot to shut down,is very under rated!

Very power hungry,will make your car die!

For the very seriuos competitor only,if you plan on running this at 1 ohm you'll need an alternator upgrade,new battery,and 0 ga. wire,I have a hard time finding subs that won't blow with this amp,it's a monster!I have a friend that had his benched at 1 ohm mono,the paper says 1684 watts.
