Hi, great solution. Can you tell me Bose goes with amplifiers? I just recently installed jbl in a circle in my Q2. And the result surprised me, since the stock audio system had passive crossovers, and the Jbl had active ones. At first I thought there was no difference, but after reading the comparative review https://electrowebs.com/difference-between-passive-vs-active-crossover/ , I realized that it is better to use active crossovers for sound quality, although they are more expensive.
