Needless to say this is strictly an spl sub. I have it in a fiberglassed 6.5 cu ft box tuned to 33 hz and this thing gets nasty low. In my explorer it peaks at around 45 hz, but itll play down to 25 hz smoothly. Now that I'm running enough wattage and no longer clipping the sub sounds perfect, and got much louder. And its only being pushed with around 800 watts rms! Enough to flex my roof, windshield, windows, doors, but not enough to be doing hair tricks and what not. Maybe its because its in an suv, but in anything smaller it would be death. Overall great buy! FYI this is my second one, the first one blew. Still havent determined the cause but Sonic replaced it. You guys are the best 5/5!

A friend owed me money so he gave me this sx18 brand new and a 6cu ft ported and I put it on a hifonics amp pushin 1200rms in my 94 suburban. It makes me breathe like crap. It was more than I expected from this sub and the sound quality is awsome from zz top. To oldies to hard hitting rap I REALLY recomend ths sub or any RE subs. The reviews speak for them selves and Sonic is the best site to buy from.

I Have x2 of this RE 18 Inches 2 Ohms installed in my MPV. It really rattle my whole car especially the Roof & my rearview mirror all the way shaking. I Drive my x2 RE 18D2 by Hifonics BRZ2400. I Really recommend to those Car Audio Fanatics this RE 18D2. Pounding bass....
