^^^the newer and more complicted the vehicle, the longer it takes. there is less room to put everything, and sometimes a lot more peices to take apart to do it correctly. i would ask them where they ran into the time-consuming issues. it will give you a heads-up if you decide to work on the same vehivle in the future. nowadays, just about anybody can be an installer/retailer, so you pretty much have 1-2 good shops in a town that shares buisiness with 3-10 more revolving start-ups, so you have to do your homework. it is real hard to take the approach of knowing better than the tech, so thake the customer approach form the start, and pull out your technical background card as a last resort. as for the line voltages, that is the recommended settings, but your amp will only put out so much, and trying to push beyond that will only bring clipping, distortion and heat. i'm sure you have set by ear before, but the approach i take is to keep the bass on the hu turned down as far as effectivly possible, to keep sq up in the full-range drivers and adjust the gain on the subs so that you can adjust it the lowest you will want at the hu, and still bring it to full power when you want, and not encounter full channel distortion or mid-high overpowering before hand. then, slight tweaks from there. as for the slope, try both settings. the 24db/oct. setting is recomonded as a initial or fail-safe setting, but the 12db/oct setting can also better smooth the transition from sub to mids. play sweeps on both settings and see what sounds better. the infrasonic/sub-sonic filter is also per-application, so try both ways, and watch excursion at those levels to see if it's needed to protect against that, and then listen for an audible difference. if it cannot produce sub-sonic levels, then you may save on some heat/load. so in short, start off with questions when you go in, then make requests, and finally demands as a last resort if you are real displeased with them not taking care of your needs. /.02
