I am currently looking to install a different set up in my 2012 Azera. I currently have 1 13w7 with a DDm2c. I want something with more cone area and deeper bass. I only want to spend 500 (total) for the woofer. I only have 5.45 cu ft (gross) so now I dont know rather to try 2 AQ HDC3 12's, 1 EMF Banhammer 15, or 1 AA Mayhem 15. Since I never had any experience with these brands, I'm looking for some insight on which would be a better choice for clean deep interior cabin bass. I have had my 13w7 for about 8 years now and want a change. I will be running the DDM2C on the new set up as well.
