Worst case, add a small beam that runs front to back or side to side. I think it would be fine.

How would the light detect clipping on the output of the amp? I would imagine it works similar to a DD-1 (as for accuracy, well that's another story). My thought is that if the clipping light is detecting at the speaker output on the amp you could do: 1) Amp gain all the way down 2) Turn head unit volume up until clipping light barely comes on or is flickering 3) This is max head unit volume (might want to go a few down to be safe) 4) Leave head unit at this max unclipped volume 5) Turn amp gain up until light barely comes on or is flickering This is all theory btw, someone would have to test. I would but my head unit goes 62/62 no clipping, so it wouldn't really prove anything.

If you take a look on sundown's site, They recommend a .28 cu ft box for sealed and .5-75 cu ft ported & 35 hz. Sub displacement is also .08 cu ft. If you haven't cut the factory box yet, I would just try it and see how it sounds without modifying. If you're unhappy with it, then you can begin experimenting. Remember that one box size/tuning isn't perfect for every car so it might require some playing with. If you do go with a ported enclosure that is a bit on the smaller side, you can stuff the box with polyfil to give it the effect of a box that is a tad larger. My opinion though is keep it sealed with original factory box or build a new enclosure with proper airspace for ported. A too small ported enclosure may end up disappointing you after a lot of work.

Yeah I usually use musician's ear plugs or whatever they're called. Makes it manageable and other people around can deal with it for 30 seconds lol. I'm interested in what that 'gain overlap' means in the manual. Does keeping the speakers attached result in you tuning 1-3db higher than you should?

In the manual it states: "Disconnect all speakers connected to the amplifier. (This has already been calculated into the equation and provides 1- 3dB more gain overlap on unregulated power supply amplifiers and 0dB more gain overlap on regulated power supply amplifiers)." For some reason this gain overlap isn't clicking with me. If I kept the speakers connected, how will this effect the end result? For example, if I have speakers rated for 100W/ea and the amp does 120W/ea, I would keep them connected while turning up gain, monitor the DD-1 to make sure I don't introduce clipping, but also listen to the speakers to make sure it is not clipping. Thoughts?
