Review: Polk Audio DB522 DB+ Series Speakers Are a Fantastic Upgrade for My Jeep TJ Front Speakers! - I recently installed the Polk Audio DB522 DB+ Series 5-1/4" Coaxial Speakers in my 2002 Jeep Wrangler TJ front speakers, and they’ve absolutely transformed my audio experience! These speakers fit perfectly in the factory location with 3d printed adaptor, and installation was a breeze, taking about 30 minutes. The sound quality is outstanding—crisp highs, rich mids, and surprisingly punchy bass for their size, thanks to the 300W peak power and marine-certified design. Whether I’m blasting rock on the highway or hip-hop on off-road trails, the audio stays clear and distortion-free, even with the top down. The IP65 waterproof rating ensures they handle dust and splashes like champs, perfect for my rugged adventures. Durable, stylish, and phenomenal sound—highly recommend these Polk Audio speakers for any Jeep TJ owner looking to upgrade their sound system!
Review: Very loud speakers - Very impressive speakers. Built a box with Bluetooth amp and use it for my boat. They get banged around and wet and always sound great.

### ⭐⭐⭐⭐⭐ Polk Audio DB522 DB+ Series Speakers Are a Fantastic Upgrade for My Jeep TJ Front Speakers!

### ⭐⭐⭐⭐⭐ Very loud speakers

Very impressive speakers. Built a box with Bluetooth amp and use it for my boat. They get banged around and wet and always sound great.

### ⭐⭐⭐⭐⭐ Great Exterior Speaker upgrade on a 2015 Lance 2295 Travel Trailer
*by L***. on August 3, 2025*

Replacing PQN ECO 50 (5" Dia) Waterproof speakers on the exterior of a 2015 Lance 2295 Travel Trailer, which only has 1 1/8" speaker pocket depth. I added the DCO 1" Universal Spacers for 5.25" to 6" speakers, as listed by Amazon as frequently purchased together with these Polk speakers. These spacers' mounting holes matched the existing PQN Speaker holes on the side of the Lance travel trailer and the predrilled holes in the spacers matched the Polk speaker and grill holes perfectly. I used Gorilla Glue's clear silicon caulking during installation to seal the spacer and speaker assembly to the side of the Lance. The spacers and speakers installed easily and look good. If you use the PQN Speaker holes for mounting the spacer and predrilled spacer holes for mounting the speakers, the speaker grill will be slightly angled. If this bothers you then you'll have to drill new mounting holes. The speakers once turned on and letting warm up for a few minutes, provided sharp sound at midrange and above. The bass was also sharp, but just about what you would expect from a 5.25" speaker. Pretty good bass, but it is not the speakers' strong suit. Build quality is impressive especially when compared to the PQN speakers that are used by the manufacturer because the speakers use low wattage and are light weight. The Polk speakers have some weight, due to the good sized magnet. I'm happy with the upgrade and would recommend these speakers.
