im going to be running the sax-100.4 amp with a set of 6 1/2 components in the front and some 6X9 in the rear, deck is alpine cda-9885.

my question is how can i run the front components speakers and the rear speakers active using the same amp ?

i thought i read somewhere you can do that with this amp im just not sure how if it only has 4 channels. isn't it one channel per speaker? or should i just run the front with the amp and rear of the deck ?

any suggestions or ideas would be appreciated thank you!

Do your components have a crossover?

yes they do

Then you can't do active. Unless you cut the crossover out.

Right. If you hook them up to your amp that would be passive. In order to do active you remove the crossover and hook up each speaker to a separate channel. You can only have 4 speakers with that amp.

In an active setup, each speaker needs an individual channel of amplification. You also need a way to control this channels frequency. (Through the HU, an external processor, or at the amplifier.)

Anyone can "go active," but I personally wouldn't recommend it for a newbie.

Head Unit --> Crossover --> Amplifier --> Speakers per speaker correct?

You won't need an external crossover with that amp, it has all the needed crossover settings built in.

so i should just run the front with the amp and the rear 6X9 from the deck? would you run the system passive or active?

Ditch the rears.

For you I recommend passive.
