Why use 2 amps instead of 1?

[huggy54]

1) A question, is it better to have a single 4 channel amplifier to run front components and a sub/s or a seperate amplifier for the front components and subwoofer. Please explain why.

2) I been looking at components speakers is it better to get components which have the tweeter seperate from the speakers and a crossover or components like VIBE's SA range with the intergrated tweeter and to my knowledge no crossover. im jus a bit confused.

i know that im doing a show install and its recommended that you use a mon blobk amp for the sub and then an amp for the front comps and may be rear speakers.

But people do use a 4/5 channel amp to run fronts, rears and a sub.

My Vibe SA50's have got an in-line crossover on them

personally i use to to allow greater control to the speakers, but no reason why not to use just the one

Whats an inline cross over, i thought components have the cross over and tweeter seperate. tell me is it better to have speakers, tweeters and cross overs seperate or inline, does it affect sound quality.

[saxo_2004]

having a crossover is better because it seperates the bass from the mid range sounds and gives a more crisp quality sound.

an inline crossover does exactly the same thing as an external crossover just in a different way.
