Those speaker setups are TERRIBLE.
Go with a Wetsounds Stealth6 or Stealth 10 Sound bar and down the line you can add in a SSV Works Glovebox subwoofer with it for a truly great sound and simple install.
If you want to go with a speaker route you can do SSV Works lower kick pod enclosures $150, JL Audio Bluetooth Controller $100, JL Audio MX280/4 Amplifier $250, and Lower speakers of your choice we've been doing the Marine JL speakers $299. This setup will allow you to add two rears in down the line.
But seriously ease of effort, Wetsounds Stealth 6 or Stealth 10.
So are you saying I do not know what I am talking about??? Have you actually heard this system??? It just became available a little over and month ago. I not only own it but I have heard many other and I have pretty high standards in stereo systems. I have a full blown JL system in my boat so I know good sound. You come on here trashing something I seriously doubt you have never heard just to try to sell something you are pushing....not a good way to get business in my opinion.
I've been doing audio for 15 years, i'm not here to start an argument at all. I have two machines sitting in my showroom with those door speakers and Polaris amps. I sell ALL of the products you talked about, and I talked about so there's no agenda behind me pushing one or the other besides what we know works best.
I've used those MB Quart Rear in multiple builds. They're huge and obtrusive.
For the money spent, there are much better and simpler options in my professional opinion. I'm not saying your machine sounds terrible, but if you'd like to me break it down further I can.
Polaris utilize proprietary wire harness, connectors, and cables to hook up their speaker systems. They often get costly and turn into a big night mare to install rather than using Power, Ground, Remote, accessory, Speaker Wire, RCA's, ETC. You're paying a lot of money for Polaris to put their Margin, The dealer, and the actual manufacture. So in all theory you end up going away from the Polaris Stereo, You can save a little dough and a little head ache.
But that's just my opinion. FWIW
