Sub + Amp, how should i connect them?, Yes, another audio tread, tried the search already... Options

[Ugglan]

Hi!
I have the basic four speakers and no amp in my car. Now it is time to get an amp and a sub.
I don't know much about this stuff so I'm grateful for all help I can get. I'm right nog thinking about buying a 4 channel amp and connect two of the channels to the sub and the other two to my current speakers. Is this a good idea? Is it even possible?

Is there any big differents between 10" and 12" subs? I want a relative small sub so that i can use my trunk without takeing the sub out.

Alot of you people are forgetting a valuable information for people who are just getting into sound systems.

Mono Amp = Low frequency amplifier and the best one for powering subwoofers, but you cannot amplify speakers.
2 Channel Amp = Amplifies 1 pair of speakers and subwoofers. You can do 2 pairs of speakers but you will lose the 'fade' feature.
4 Channel Amp = Allows you to amplify 2 pairs of speakers and subwoofers.

Keep in mind that if you want the best power out of your subwoofers, use a Mono Amp. Alot of times, people would use a Mono Amp to amplify their subwoofers and a 4 Channel Amp to amplify their speakers. But if you're on a budget and just want to get by on a basic setup, go with a Mono Amp for thump. But if you plan on amplifying your speakers as well, go ahead with 2 and 4 Channel Amps. But PLEASE, do not amplify your factory speakers. They aren't made to be amplified. Keep in mind that 'factory speakers' are made of PAPER and will go pretty quick.

There are two kinds of speakers, PAPER and POLYURETHANE.

Paper = Good at low frequencies, bad at mid and high frequencies.
Polyurethane = Bad at low frequencies, good at mid and high frequencies.

Low frequencies = Bass!!!
Mid frequencies = Instrumentals
High frequencies = Vocals

Most aftermarket speakers are made of Polyurethane and that is why they give you that clear crisp sound that everyone likes out of speakers. Most 2 Channel and 4 Channel Amps will amplify mids and highs on speakers where as subwoofers will only draw in low frequencies. Having polyurethane speakers and subwoofers is the best setup and will give you the best balance of lows, mids, and highs. That is the key of a good sound system. And yes, when it comes to aftermarket speakers and subwoofers, BRAND name does matter!

Good post!
The factory speakers are made to be amplified, infact all speakers can be amplied. Its just a matter of how much can they handle before the core starting to dislocate, but I am sure thats what you mean
