So im in a debate with myself, i know these amps are closely related. But im hoping somebody can give me some info that will help me decide which to run.

Im gonna be running on 4 15s at .5ohm. Its between an American Bass VFL500.1, Cactus Sounds 5k, Incriminator Audio 40.1, or an RD D9. I have the electrical to back any one of these amps so thats not an issue. Its mainly a daily pounder I play music on a daily basis. And i will be competing from time to time but not more than like 10 times a year.

Help me out guys thanks.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

what's your competition based on? watts, sub size, etc? the D9 is my favorite 900 watter.

 
Maybe its me and someone can confirm this for me. But to me it looks like the D9 guts are a little beefier than the other amps I stated. One big difference i see, is there is a full additional row of caps in the D9 over the rest.

 
D9 is my pick too...

D9 is based on a Zenon board, but I believe that it was significantly upgraded over "normal" versions. The guts are beautiful for sure...and it runs daily at .5 without breaking a sweat. I've played music very loud at .25 ohms also (as well as burping it)...although I wouldn't recommend it.
