I bartered a set of used tires for a sealed box with set of 12" Punch P2's and a 500W Jensen XA 2125. I also replaced my front door speakers with 6 1/2" Kenwood Excelon. The guy that installed wired it for 2 channel and adjusted it. He really didn't explain how I could tweek it for my taste, other than turn the "level dial" down if it hits to hard. I don't listen to hip hop, mainly older rock and roll (70's-80's) and could use a little advice on tweeking it.
The amp has four adjustments. Bass, L- CHX, R-CHX, and Level.
My previous set up in a 2 door Yukon was adjusted right for my listening taste. I could adjust the HU to make it feel like a sharp punch in the back instead of the long vibration I'm getting now in a 4 door Yukon.
Forgive me for not speaking the lingo, I don't mess with this stuff much.
