BRAND NEW RE AUDIO SX18D4 18" 1,000 WATT RMS RATED (2000w PEAK) DUAL VOICE COIL 4 OHM CAR SUBWOOFER WITH TRIPLE STACKED MAGNETS AND A CAST ALUMINUM BASKET**FREE SHIPPING****HAND BUILT IN THE USA**
RE Audio is known to make some of the best hard-hitting subs and amps. These are competition grade subs, which go super-loud. These are made with triple stacked magnets, so that they can push out extra power. These subs have cast aluminum baskets to withstand abuse. These subs are strong, powerful, and they sound really good.
These subs are made to pound bass for long periods of time without getting damaged over time. With 1,000 true RMS watts, this sub is one of the most powerful 18" subs on the market. These are rated strictly. They do not have inflated peak ratings like some other lower brands do. This sub can easily handle more than 1000 watts! That is how good they are made.
This is a 32 pound monstrous high excursion sub. This means it can hit a big range of frequency, and it can also pound a lot louder without over-heating. Since this is an "18" sub, you can expect to have the deepest bass out of anyone else! The bass on this is so deep, that it will cause car alarms to start ringing when you turn it up.
(Make sure to use an amp with enough power to feed to this power-hungry, insanely huge 18" sub!)
