Mga gurus. I'm planning on installing 4" coaxials in the QUARTER, located in front of the sail panel of our innova. It's the tiny useless window right next to where the windshield ends. Is this a good location? Tight lang ang budget and coaxes are cheaper and I want to keep the A-pillars stock (no tweeter, midrange pods). Do midranges need enclosures? Baffles lang kasi ang gagawin ko for the 4inchers.
