I just ordered my JL Audio's for the sound bar. Came today, so my try and install this afternoon. These are not a marine speaker but have always had JL subs.
Edit: sorry I didn't have info...I know most use the Polk or kicker replacements. I'll use some poly fill myself in the sound bar. I will have my factory HU right now, depending on how it sounds I may add an amp. Most say the HU is under powered.
