Improving sound quality one step at a time.

1Five1 Garage

While we replaced the Bronco's cheap factory speakers with a higher quality one there was still some room for improvement. This was a total trial and error type thing and wasn't sure if it would make a difference. Well.... we found out..

why not use speaker baffles?

I used the baffles, they fit with a little trimming around the edges.
Also used polyfill stuffing behind the Polk speakers.
Am Dynamatting the rear pods with polyfill.

Did you buy DB402 4” ROUND COAXIAL SPEAKER? how do you like them?

Yes, I used the Polk DB402. They definitely sound louder and clearer, the highs go much higher than the stock paper cones.
Little weak on bass, wasn't expecting much from a 4", but there is no more bass in my opinion than stock, even with the baffles.
I picked up the 6-1/2"s also but haven't put them in yet, I hope they perk up the bass a little, otherwise a small sub may be in order.
By the way, Walmart has the Polk 6-1/2" to match the 4" for $59.00 a pair. Had to pay $79.00 a pair for the 4", best price I could find.

Many folks are using the kicker brand not sure if that has better sound based I. The forum

Been reading options to add base and found JL swing gate sub that I think could be adapted to the bronco or a bronco option to come soon
