Alpine S2-W8D4 8" S-Series Dual 4 Ohm Car Subwoofer, 900W Max, 300W RMS

Has good weight to it. Good clean bass, Fits in the OEM subwoofer spot. Excellent quality and function. Easy to install. High durability with more RMS and PEAK POWER than is needed, but still able to put out clean sound from amp. Replaced the OEM sub in a Ford Bronco while keeping the stock B&O amp. The bass is now amazing and NASTY. Couldn't be more pleased. I did have to add some foam around the plastic panel to stop the plastic from rattling because of the extra power from the speaker. Good value for price too.

Great bass response! Good price!

Speaker was easy to install and sounds good out of the box.

I'm glad with this purchase. I needed something that required very minimal cubic feet of airspace. I made a sealed box that had about 0.23cf of airspace and the bass sounds great. I like that the wiring diagrams are clear and accounts for your different wiring scenarios.

If you have a Tesla with the premium system, do it. The difference it made it's incredible, and that's using the stock amp.
