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?
