Trouble finding the right amp and setup
I'm trying to find the right amp solution for my needs but I'm having some difficulty choosing between brands and also the type of setup I should go with. I need an amp or amps to drive 2 front speakers, 2 rear speakers, and 1 12" JL sub. I'm not looking for a whole lot of wattage, just something around 50-70W for the 4 speakers and 150-200W for the sub. It's an older JL with a rating of 125W. I used to have 125W running to it and it suited me just fine. My original thoughts were to go with a 5 channel amp and I had pretty much decided on the Hifonics Z8000. But, I got to thinking that if my wife drove the car she may not like the bass. So, I was thinking that If I use 2 amps, I can probably put a switch on the sub amp and be able to turn it off. Now this is where I'm stuck. I don't know whether some brands are good or not. I don't want to spend a fortune as I'm only looking for good sound quality. I've seen that coustic, cadence, SPL, and power acoustik are fairly inexpensive, but I don't know much about these brands in terms of quality. I'm also not sure whether I should run a separate crossover or use the ones that are on the amps. One feature I like on some crossovers and amps is the remote bass control. Maybe these are useless and someone can set me straight on the matter, I don't know, but it seems like it would be nice to adjust the bass a little from the front.
So let me know your suggestions on amps and whether or not I should use a separate crossover. And please don't just say "X" brand amp *****. Give me a reason so I can learn why a certain brand is crap.
Sorry for the long winded post, but I need some help and don't want to choose crappy amps or go with a bad setup. My rear speakers are kenwood 6x9's and the fronts I haven't purchased yet, but I'm leaning towards JL or Infinity components.
