On Black Friday of 2008, I got these subs plus an 800 watt Xplod amp from Circuit City for $180, after tax. After barely squeezing them into the trunk of my '99 Ford Escort LX, I hooked them up using 8 gauge wire for power and ground to the amp, and high-strand 10 gauge to the speakers. At 340 watts RMS, these things pound! The entire interior of my car rattles; while running a test that slowly increases the frequency, you can hear different components of the car vibrate. They seem to like 48 Hz, +/- 2 Hz, but that could just be the settings on my amp. At 48 Hz, my Garmin Nuvi 270 is unusable (when you go to touch it, it pounds at your finger because of the vibrations, while tilting upwards on its mount). With the right song, they're ear-splitting, and will give me headaches after less than five minutes (even though I'm used to them). The excursion isn't the best, so you don't feel the pressure as much as the actual shock of the hit (it feels like a mild full body massage, if you have longer hair, you can actually feel it vibrating). Outside the car, the sound carries, but you hear the bass more than you feel it. In other words, they're cop-friendly. A larger amp might change this, however. For a first-time setup that'll impress most of your friends that didn't dump more than $500 into a *good* subwoofer setup, this isn't bad. The sound quality is OK, songs with a strong beat sound better than those with a fast one (rap vs. trance/techno). They're designed for low frequencies, thus, if you don't have good speakers to handle the 80-180 Hz range, you might feel like you're missing something. Beware, though, the box is enormous; fitting it into my trunk took some planning, a flat tire would make me extra-miserable, and a small child would barely be able to fit in the trunk with the box. The tradeoff, however, is excellent sounding, head-throbbing bass.

Short and sweet these speakers not only look absolutely gorgeous, but they also can really bump. Just be careful you don't shatter your back window with them (yes, that can actually happen). I only hooked mine up to a 1000 watt amp and I haven't even pushed it to half way yet and my ears are hurting. A+

These subs was a upgrade for my car audio, a "95 Saturn SL1. I am using a Sony CDX-GT820IP CD player, 4 Sony 5.25" mids(4-way), 1 Sony Xplod 1000 watt amp (mono-bridged), and these subs. These subs can handle a lot of power. They are great for people who are bridging there amps. My next upgrade will be to "Dynamate" the rear trunk area, It Basses so hard, I can feel wax coming out my ears. I will also upgrade with a 1.5 farad capacitor due to dimming lights. For this price not bad at all. Cop 'em.
