Summary: I use this product to produce a lot of bass.I have one pioneer that is ran at 1ohm running 1200 watts handling every bit of it. The bad thing is that they are plastic cones and while cold don't sound as good like they are when warm.
Pros: Compact, Easy To Install, Great Power, Great Sound, Versatile
Summary: In a 1.25 cf pre-made sealed hatchback box in my 04 Taurus's trunk. Powered by an old Power Acoustik stereo amp with a 20-amp fuse (maybe 120 watts @ 4 ohms full blast). The driver is wired to the amp, which is bridged, in series for 4 ohms. This setup pounds the poop out of my car. My mirror jumps with kick drum hits. Putting the rear seats down is awesome. Double bass drumming is epic through this thing. Never misses a beat or note.
Summary: Great sub for the money!(Best Price ive found on this one) I have an older 800W pioneer on it so its actually underpowered a little bit (Amp = 360rms sub = 400rms) but it can still beat and raddle the inside nicly. Not a whole lot of outside sound butthats what its not about. Like I said the inside sound sounds great and is LOW.
Summary: Well i was planning to buy the older model(307d2) but i saw this newer model has better stats and is just couple dollars more and it would be more valuable in the long run. I knew i wouldnt be able to run this one sub at full power due to me using a 4ch amp to save money and only use one amp. My amp is rated 80w rms x 4 and bridged at 225w rms x 2, so i use it to power 2 speakers and sub bridged in a 1.5cu vented box.
Excerpt: Da muy buenos graves, pero necesita un buen cajón para expulsar mejor el aire. Parece muy grande en los cajones de 12" prefiero uno de 15" pero viendo el rendimiento que da este preferí comprarmelo, además que la potencia es una barbaridad, son casi 500 wrms y 1400 max. Solo he visto el d4 de pioneer que era mas potente y es que ese se iva a 200 euros y casi el doble de potencia.
Pros: Su capacidad para reproducir las bajas frecuencias y su gran potencia
