First true competition build

[OMGitHERTZ]

Hi all. I'm in my 40's and have never been without a system since age 15. I've tried all types of combinations over the years, but have never built anything that I would consider competition level. So. I've been going to local bass wars for a while now. I would like to try the lowest class. I'm pretty much limited to a pair of 10's and an amplifier that is "advertised" as a 3k. So I have one run of 2/0 from the mechman 370 to the 100ah limitless lithium battery. The amplifier is an Orion Hcca 3000.1dsplx. I intend to run it at .5 ohm. I have no idea what tens to go with. Nightshades?Ampere audio encores?Hutchinson NFEB1? Cheap ass HCCA? The possibilities are mind boggling. The desired outcome would be 150 db at any frequency sealed or not, with the sensor placed anywhere before the headrest. The car is a 2009 VW GTI 2 door with EVERY body panel, to include the roof and floor, covered in 320 mil rilla mat deadener. Any suggestions as to which driver would make my goal more likely are welcomed. Bonus points if they could do the number and actually play music. Thanks All!
