Did you readjust your gains? Are the outputs the same?

[mylows10]

[OmegaBunny]

Was gonna say the same thing

Op, Boss is like bottom of the line car audio. you went from a good deck to a shit deck.

Don't forget the gains as well.

OP, switch back now or change those gains or you will lose your sub stage.

You down graded rather than upgraded of performance.have you adjusted the RCA input to match the new HU?as well as make amp adjustments as stated.For better SQ,and Performance,if you still have the old deck, id recommend putting back in, or upgrade to a better unit,if you do not want that one.I went fro an Eclipse cd3000 to a Clarion 302,and did not get but worse, put back in my Eclipse, and have been quite happy

Boss is hardly what the name suggests.

Take the boss out and throw it away..
