Diamond d3 are real good subs i have two of em in a kicker cvr box "which i know isnt the correct box lol" but they do get very loud and they hit real low and they are very under rated in power they can handle more than 800 max i run 600 rms daily to mine and they dont even get warm and they hit hard but they do get sloppy on some notes. now if you want to spend more money go with the d9s i have two 15" d9's in a zr1 blazer and they a ridiculously loud.http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=19475. This is the ultimate budget subwoofer. A friend of mine has one in a 2.0 cubic foot box, maybe a little bigger and it get Loud, Low, Clean, and Deep.
what model did you go with?well, the AP's in. There's not a significant difference, but I DO think this one deals w/700 better than the Lanzar did. I thought the Lanzar was getting about as much power as I could safely give it, but I don't get that feeling from the AP -- it sounds slightly more authoritative.
I'm always shopping though. No telling what I'll end up with.
See what you do is buy the pyle's paint the dust cap and viola nobody's the wiser lol. You can tell people they're custom built.http://cgi.ebay.com/2-New-15-Cerwin-Vega-Subs-HED-15-4-DVC-Subwoofers-NR_W0QQitemZ380085328199QQcmdZViewItemQQptZCar_Subwoofers_Enclosures?hash=item380085328199&_trksid=p3286.c0.m14&_trkparms=72%3A1234%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318
