Bangs but isnt gunna last lomg ive had like 3-4 of em and once that burnimg smell starts you got a couple punches and coils gone ,and no i didnt hook up wromg since i moved to ameeican bass and diffrence

It's an awesome sub, but the best but listing needs to be corrected. It is not a single voice coil sub, it is dual 4ohm. Now back to the subwoofer. I've owned a plethora of car audio and Alpine has aways been top notch. The S series are on the lower end of what they have to offer but still impressive to say the least. They handle every bit of 600 watts. Freauency response is pretty good as well, only lacking moderately at the low end. I definitely recommend.

Good base, very light wooffer for a 600w. 1 is loud 2 will rumble more. 300w rms each voice coil.

It sounds good, but I would recommend two. They don’t hit the really deep lows, but the Xmax is only 14.5mm. For the price range you can get something better, but when they go on sale for $99, get them. They’re worth it. Fun fact: I pushed about 1200W through 1 S-W12D4 and it took the power for a couple songs before one of the voice coils burned up and smoked my car out. My mistake, I thought I had it wired to 8 ohms.

I powered this Alpine subwoofer with the Alpine 600 watt (300 watt rms also sold at Best Buy) mono amplifier and it bumps! I listen to all types of music and it all sounds good. Bass can be very deep, shaking everything! It can be configured for 2, 4 or 8 ohms via terminals. I highly recommend it. I have it mounted in a Metra Sub Enclosure (sold at Best Buy) in the cargo space in my SUV.
