With 600 watts you should be fine and really nothing to worry about, just dont jam at idle and if you notice some dimming then turn it down some. Installing a volt meter will always be your best friend when it comes to monitoring your voltage and the only way to know if your truly safe or not.

They are amps that will provide your subs with some bass, if they fit your budget and power needs then yes they would be good for your application.

I had that problem before with a knob and therefor just didnt use it at all, and dont use them nowadays since I dont really need them.

Here is the only box size recommendation I seen him make in his topics: SPL-15s, recommend enclosure? - SSA Car Audio Forum

Yeah a 150A fuse will be find, music is dynamic so you wont see 1600 watts anyway.

1/0 AWG is 0 gauge

, never tired of seeing pictures.

sounds nice

Im liking the progress

Yeah usually a fuse is for a wires protection and to protect anything on its path if something were to happen.

More than likely one of those CVR's in a ported enclosure will be louder than those two in a sealed enclosure or right around the same ouput. If you can post both of those CVR's but if not then yeah the BL would do the job too.

Really is no such thing as break in, the subs suspension is stiff and will loosen it up the more you play it. The harder you play it the quicker the suspension loosens up, a lot of people play them how they would if they were a year old when they first get them.

The phase is relative to your system and how it interacts with the other speakes and environment, so play around with it but most do leave it at Zero.

Im have not use the couplers and would rather buy some new wire when it comes to power or ground wire that is the actually size I need to avoid any mishaps. Will they work, yes since they are selling but I wouldnt use them (just a personal preference). Now if it was speaker wire then I wouldnt mind, I just dont take chances when it comes to ground and power wire.

They have shallow components nowadays, check those out if you feel 4 sets are necessary. If you really want a wow factor and want to be loud then go for horns, I used to be wowed by a lot of speakers but when you can shut down a car with 8-15 interior speakers and you only have four (feels damn good and is an even better wow factor).

Good luck and dont forget to take some pictures during and after the install

Why do you want to do 4 sets of components just in your doors?

That is a hard one right there but it seems like your worried about output so I would lean towards the 2-12" SA-12's. The Xcon isnt a driver to pass up on neither, why not look at a 15" Xcon instead of a 12"?
