Upgrade Audio with dsp + sub

Hello everyone first of all congratulate for this amazing forum, I'm from Italy sorry for my english.

I decided to upgrade my audio system (bmw 1 - E87) with a MB Quart kit for the front (midrange and tweeter) and a pair of woofers under the seat.
Then added a subwoofer and to complete everything I replaced my "business" radio with "professional" (USB predisposition) and finally connected a match pp52 dsp.

I connected the dsp to the control software match, despite the many tests carried out the results are always poor and especially on low frequencies, completely absent despite the use of a sub in addition to the two woofers.

Is there anyone who may want to give me a hand?

I seem to recall some where that you have to code your car when you switch from the business head unit to the professional to get proper sound.

zx10guy Yes it's all ok, I heard difference from old business unit, but very poor result with dsp and sub, I used the match software for cuts and slopes...
