yea everyone's opinion is always going to be different. Like instance, I prefer Pioneer over Alpine. and there's nothing wrong with that. They're two both really good products that are out in market. They both do almost exactly the same, give and take a few options. But knowing you, cuz all of us guys are the same, we want looks and sytles as much as output performance! I mean just go to www.alpine.com and www.pioneerelectronics.com and take a look for urself. Alpines have a few HU that looks nice, but i like Pioneer overall.

hmm...Alpine subs, like their type S, hit really good. I'll give them that. Pioneer subs are so-so. Are you looking to keep all the components within the same brand or something? You could get a better overall sound going with different aftermarket components.

With lcd monitors, looks come into play for me. Well i still think pioneer has a better quality picture but that's just my opinion. You kno wut brand i think is really good but underrated?!? CLARION! They're so clean! but hella expensive.

Cd changers are cd changers. Nothing special about them. Both do the same job.

Hey aren't PPI's...Viper now? Well anyways...yea viper took someone over. Haven't heard much reviews about them. Well have fun!
