Utilized these to supplant 14-year-old Power Acoustic speakers in my Toyota 4Runner. The A-Series Pioneer speakers gave my music crisper sound with parcels greater clearness. The bass isn't comparable to the speakers I had previously yet I'm fine with that. It's presumably better to get a subwoofer in any case. The main drawback is that not at all like the 6.5" demonstrate which had numerous screw gaps for different mounting types, the 5.25" speakers just had 4 screw openings (in a square example) though the mount on the vehicle entryway had just 3 gaps (in a triangular example). I needed to bore extra openings to keep the speaker set up BUT it's most likely a greater amount of the vehicle's blame for being structured that way. Yet it would have still been pleasant for Pioneer to incorporate those additional screw openings. Visit http://www.stereostefan.com/ https://speakerdeck.com/gazleba
