So.. I've searched, and other than posts about putting a "sub in a box" in one, I cannot find any info about a subwoofer in a 260EC/270EX. I was thinking about adding a 10" sub to the boat and am looking for advice on where to put it. Where does the factory sub option (is there one?) go?
I found a deal on a JL audio sub amp (new, no refurb): https://www.crutchfield.com/p_13698402/JL-Audio-MHX300-1.html
If I have the depth, I would get the "good" JL 10" (infinite baffle model).
I've also debated just paying "Soundwaves" to come and choose it all for me.. but that's not me.
