Never understood the distaste for aftermarket stereo equipment, unless you're just one of those guys who wants their interior to look stock and un-modified (which I DO understand that, especially with the older classics)
with the right install job, an aftermarket radio can almost blend in and look factory in my mind anyway.
and I even have this hiding behind the seat. it's not going to rattle the windows or license plate, you won't hear it thumping from a mile down the road, but it gives me a nice, full, rich, deep sound.
Door speakers are Alpine components hidden behind the factory speaker grills.
