I was going to buy a 2020 Honda Ridgeline but a couple of weeks ago decided on a Passport Elite. I just bought the Passport a couple of days ago. One of my favorite online vendors is Crutchfield and when they have sales I have been buying audio devices from them over many years. They had a great sale on the Polk (another favorite of mine) speakers so I bought the DB652 coaxial speakers, two pairs at the beginning of summer for the Ridgeline. I was happy to find out they will fit in the Passport's front and rear doors. There is a small amount of cutting the back of the plastic speaker grills for proper fit. I also got the proper speaker mounting brackets and plug wiring connectors. I used this same model speakers on another truck I use to own and was happy with the result. If you buy them from Crutchfield you get a 56 page instruction pdf for the 2019 Honda Passport. If anyone decides to go this way the speaker mounting brackets are HSB524 and the connectors/wire harness is Metra 72-7800. I can not guarantee these products will fit/work until I do the install in the next few weeks. Also some on the forum may have already done it. If not I will try and start a new thread with pictures. I hope to sweep the response before and after but what really counts of course is if I like the sound. Since these are coaxial with a tweeter I will probably also replace one of the originals with a load resistor and sweep the amplifier to see if it is full range or were it rolls off.
