Review on DKMUS Speaker Adapter Corolla Highlander by Rushabh Gonsales

I bought this item for my Lexus is300. The rings seemed strong and well made. The plugs also fit the car. The mounting holes for the speakers matched up pretty much exactly. However, the holes for attaching the rings to the door have been disabled. I used a hole to attach it to an existing hole on the door with a bolt and nut. The remaining 2 inches had to be tapped to complete the installation. Another issue I had was that there is no cutout for the connector wires. I just had to walk between the door and the ring. If it's not a pity to make some improvements, then the kit is worthy. I basically chose this connector for plugs so I didn't have to cut and splice.
