Because the amp is for a sub you will set the "Frequency" to low-pass, punch bass off, the phase switch can be switched just about anytime and leave it where the sub sounds the best, there is no wrong position, the correct position is when the sub sounds the best to you.

Turn the bass remote volume control all the way up when adjusting the amp gain.

Yes, bass and treble flat on the stock HU. 94

 

Ahh okay gotcha, what number hz would you I suggest I set it at? The range goes from 40hz to 130 hz.

 

80

 

I agree, start at 80Hz, but try it all the way up to 100Hz and maybe as low as 70Hz, the low-pass x-over point, [low-pass or upper cut] will depend on a number of things, mostly how the bass sounds to you when playing the music you like. 94

 

Got it, thanks everyone! Out of all the threads I posted on other forums, this one helped the most...guess Honda Tech isn't full of haters after all

 

Any reference material regarding this? News to me, even high end home audio subwoofers generally use a cube.

 

Look inside a high end home sub cabinet.

Although there is a debate about standing wave propagation in a box with parallel surfaces, with a cube box being the worst, and it's effects on SPL/SQ...

I have built cubes for sub boxes, there are ways to deal with standing waves, one of the best ways is not to build a cube, [or in OPs case, buy one] if you do not have to.

Even if, as some say, it does not make enough of a difference to make it worth the effort, IMO anything that can be done that will make a difference should be done.

For sub bass, either for SPL or SQ, [or both] it's all about the cabinet, yes the quality of the speaker makes a difference also, but I don't care how much you spend on the sub, if the box is wrong the bass will suck. 94

 

I have mine....it's a cube

The outside dimensions are the same, [13.5" cube], pull the driver or amp and look inside the box, pretty good bet it is no longer a cube, the fact that the amp/x-over is mounted to one side of the box makes at least one dimension different, you will most likely also find bracing and dampening material inside the cabinet. 94

 

I'm just giving you a hard time, as I have heard similiar statements before but have never seen any good reference material with some science behind the statements. A lot of high end woofer enclosures are cubes.
