Re: 4 Channel Amplifier Advice
Great set of components. Those arent exactly entry level so dont skimp on the sub end.
Cant go wrong with 2 amps. A mono amp will be easier on your elec system and can take lower impedance loads (more power) but will cost more.
If you go with the 4ch amp your system will sound great and as you said it will cost less.
Out of those 2 amps I would choose the MB Quart. It has plenty of power for your component and 500w rms for a sub if you choose. Keep in mind your components come with x-overs so they will take care of the frequiencies. If you do run a sub, just make sure whichever channels you bridge (if you choose to bridge) the x-overs are set to low pass. Dont want full pass or Hi pass frequiencies going to your sub.
If you decide to run a sub you are not stuck with a svc 4 ohm sub. You have some options: svc @ 4 ohm / 1 - 2 ohm dvc (each channel @ 2ohm 250w to each vc) / 2 - 8 ohm subs wired to 4 ohm / and so on..
Also, disconnect the rear factory speakers. If you fade to the rear speakers or reduce the gains on your amp so that you can hear the rear speakers this defeats the whole purpose of getting components and a amp to begin with. Just my opinion.
As far as other amps - Crunch, Hifonics, Autotek and MB Quart are all under Maxxsonics. No experience with Crunch or Autotek and not suggesting anything, just FYI.
Hope that helps
