Today i change my HU. I put Alpine 9887. It's not good looking after pioneer f90bt, but sound so defferent. Sound so clear now and tweeter from pioneer 720prs not so high, when i using f90bt in eq i put high very low and now good sound without adjusment hu. And yeah... Front frame doesn't fit in my car... it's little bigger than my bazzel (or how call this).
Now i'm thinking maybe change sub??? i need sub can play below 15hz, JL w6 play after 20-22hz.... Maybe buy IDMAX???
What you think guys how IDMAX will play???
And i still have engine noise... maybe ground rca cable from amps...??? or bad ground from HU or amps??
