Conclusion: I purchased this enclosure from Sonic Electronix a couple of weeks ago. I installed the Polk db1222 enclosure in a 2001 Hyundai Accent, with a Sony DSX-S300BTX head unit, 6 1/2 components up front, 6x9 in the rear. Powered by a Rockford Fosgate Prime R300-4 for the mids and highs. A Prime R500-1 powering the the Polks. With a quarter turn on the gain and bass boost these subs are attacking me with some serious authority.
Conclusion: These things are INSANE. I hooked them to a 1800 watt kenwood amp and let me tell you if you have your stereo over 20 volume you better wear ear plugs because these things are amazing. WARNING: these will destroy your rear view mirror!
Conclusion: By far the best subs I have ever had. They come prewired so they run at 2 ohms which gets more Power from your amp. I'm running a Rockford Fosgate 400.1 I don't need any thing more than that. Always turning heads and setting off alarms. I drive a coupe and I get a massage every time I drive. Read over 100 reviews all positive. Buying a second set for my SUV!!!
Conclusion: Let me start by saying WOW!!! This is my 2nd enclosure ive ever had in my life and I am blown away. I did have a problem after I connected these the first night and tested them with my previous piece of crap Visonik amp. I smelled burning wires, and nothing was coming from the subs. A few days later I got a new amp (Hifonics Hif1000) and rewired all the wiring inside the Polk box.
Conclusion: This is one of the amazing subs on the market.I used to have on but someone stole it. Very powerful sub. No noise distortion. Clear bass. Need a very good amp to get the most out of it. heads will turn when you pass.
Conclusion: These are my very first pair of subwoofers. I mainly bought these because they came with a box and where already assembled. All I had to do was hook in two wires. I've got to say, for the price I LOVE these. I've already blown a Sony amp. Moved on to Rockford amps.
Conclusion: I have this box in my Chevy tracker, and all i can say is wow , for this amount of money you would expect to get jensen or lanzar or some other junk.. This sounds great and hits clean. Doesn't matter what kind of music you listen too this will defiantly help the sound. Im running a 1300 watt mtx thunder amp and no problems at all...
