I have an 84' 6.2 Diesel. I was wondering what kinda subs i should get to overpower the noise of the engine. Right now i have in it an Aiwa MP3/CD console, 2 Kenwood, 6x9 for the fron and 2 Pioneer compression horn 6x9's for the back in boxes. I was gonna buy some subs a little while ago instead of the pioneers, but the person said that the diesel engine would drown out the subs. So im asking what would be the minimal amount of sub power (size, power, and how many) would be worth while to get?!?!
