I can go to 33 out of 35 on my kenwood with the sub level on +0 and it sounds great
I can do about 23-24 before clipping with the sub level on +9... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
of course depends on how everything is setup, from the bass setting on the HU to the gain on the amp.
Turn it up and find out //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
The way I do it is set every EQ band to full boost, max out the gain and bass boost on my amp, shut the crossovers off, and then turn my HU up to 80/80.
Sounds great that way!! Learned everything I know from "Pimp My Ride"!
