## Customer Reviews

### ⭐⭐⭐ Sound quality OK for the price but some issues with quality
*by H***L on 31 August 2021*

Bought for 1998 Transit MH as quoted fitting. Not a direct fit due to vagaries of Ford design. Required some modification of the door to install.The screws supplied are completely unsuited for the speaker flange holes. Small hex socket head almost able to fit through the slots and required washers to ensure they were secure. Ultimately only used two and used flange head screws on the other 4 holes.Terminal blades are too thin and easily bent to use with push on recepticals.

### ⭐⭐ Poor quality sound, original were better
*by L***S on 17 November 2021*

Poor quality sound, original transit door speakers were better
