audio set-up for beginners [continued]

[enargie]

No need for a separate dedicated amplifier for your subs if you have a 4 channel amp powering a pair of components and s sub woofer. The only time you add a separate amp for the subs is when it is obvious that the subs needs more power.

Sir, need advise for the specs of 4 channel amp I need to choose to power a 10" sub and a pair of 2-way seps.

Thanks
