A few things I've learned over the years....First of all, unless you do all the sound deadening and all that, you're really not going to notice a slightly inferior head unit unless you're parked and setting still with the motor off. And, honestly, there are a significant number of the population that still wouldn't be able to tell. A good midrange Kenwood would work fine. I despise Pioneer personally (and actually don't know why), but I'm sure a midrange deck from them (or anybody else), would work fine also in a commuter truck. As for speakers, get a good name brand with high sensitivity to maximize your amp choice. I prefer Memphis, but there are plenty of good clear sensitive speakers out there. As for amps, I would go midrange here too. But remember that the less expensive an amp is, the higher wattage you'll want to get so that you aren't pushing them too hard. That being said, you'll find that a lower end amp in the higher wattage range you need to keep it playing clean will most likely cost as much as a higher end amp in a lower wattage that you can push to it's limits without distorting. I've built a few systems with lower end stuff that sounded pretty good because I was using only half their (claimed) ability. Of course, if I pushed them past that point, they didn't sound near as good. It's all a trade off....
