Great sounding speakers for the money. These were installed in a 1987 Buick Grand National. Absolutely no modifications necessary. It is a fairly shallow mount speaker that works great for doors or tighter locations. Overall sound performs better than expected for a speaker at this price point. I would definitely recommend these budget friendly all around good quality speakers.
