Summary: Stop researching because you have found the best sub for its price. This sub is much better than any other sub I have purchased. I am using it with a 1500 watt amp in my Honda Civic, and it overpowers my car. I've spent almost $30 on soundproof foam just to keep the sub from rattling my whole car. Definite buy for anyone.
Summary: I put these in my 20 year old stereo speaker in my house. They sound great, especially for the price. It was a pretty easy install. I stripped the wires and put them in the clamps on the back of the speakers. I needed to file out the hole in box about a 1/4 inch but that only took about 20 minutes each. Lastly, I drilled pilot holes for the mounting screws and screwed it together. I was a little afraid that this install would be more difficult then it was.
Summary: I recently bought two of these bad boys and put them in my 98 cavalier and oh boy do they bump. This is a great sub woofer to double up on and have a great sounding system. Remember though, good subs don't mean anything without a good amp and wires!
Summary: I have two of these 12in subs in a ported enclosure, and so far, they hit very hard with deep and clean bass. I will deffinetly buy pioneer again. The only concern about this product was the shipping. I chose to purchase both from 3kingsaudio and they got shipped separately. Shipping was faster than the amazon expected delivery date, but I was confused as to why any company oils do this.
Summary: Replaced my 10 inch subs with these and the differences is almost night & day. I ended up having to turn down the levels on my amp to keep the bass from drowning out my treble! Powerful speakers!
Summary: this is a great sub woofer. i originally bought one and built my own shallow box and put it behind the passenger seat of my truck. and it sounded great and really shook it, however, i decided that one just wasn't going to cut it so i ordered another one and put it behind the driver seat and it works outstandingly well. so well done pioneer and, whoever is thinking about buying this. please do because you will not be disappointed.
