New to car audio.. help me understand

hey guys, i just baught my first car, Chevrolet Cavalier 98.. I am interested in hooking up a nice system, and i hope this is the right forum to post in. I just need a few things explained if somebody doesnt mind helping me out.

First of all, im going to be replacing the door speakers which are 4x6's, does anyone know if i can get a plate to upgrade them to 5 1/4?

secondly, whats the advantages of hooking the speakers to the amp instead of to the head unit? and what is the different between a 2 channel and 4 channel amp/

thirdly, when hooking up everything to the amp, lets say i put the 4 speakers and my sub to the amp, will this cause any problems to run it all on one amp? and what is the tube thing that i see mounted to the sub box?

Thanks alot to those who can help me understand more, i know im new but i need to learn just like you all did at one time,

Shane

1 i would if i needed to i would cut the door to get 6 1/2 in there you will be happier
2 an amp will have better power 2ch = 2 speakers 4ch=4 speakers 5ch = 4 speakers and a sub
you can run a 4ch as a 3ch 2 speakers and a sub but look if it has the power to do it
3 you need the right amp for what you are doing
4 have fun

Hang tight, I just finished installing nearly all my stuff in my 97 cav coupe and will get pics tomorrow during the day. It's rather hilariously done but will look very nice after a few tweaks. Also I think you may be able to get the 4x6->5 1/4 plates off ebay or crutchfield, but I myself just made some out of some wood, it's pretty easy. I have a component set (which means the mid-driver and tweeter are seperate pieces) hooked up to a 4 channel amp. Each one of the four speakers to a seperate channel, and rather than use the little passive crossover box (which sends high frequencies to the tweets and low ones to the mids) I am just using the amp as a crossover (which gains me some power, altho maybe negligible amounts). Then I have an entirely other mono (1ch) amp hooked up to my sub(s). I'm sure you will have a billion questions about every part of these and theres a billion different answers, so just keep browsing audio websites.

I suggest:

Cheap and easy - 4ch amp powering front 4x6 or 5 1/4 and 6x9s

Moderate - same as above, with another amp for a sub or 2 (or a 5ch amp to do them all in one package, but can get expensive)

Big old bastard - 4ch powering some front components, rear (if you want them) off the deck power, and a big old amp for a sub or 2

If I understand that question properly, you are probably talking about a port.

There are 4 main ways that you can install a woofer
1. Sealed
2. Ported
3. Bandpass
4. Infinite baffle/free-air
(There are a few other ways too, but we'll keep it simple with these 4).

1. Sealed. A regular box all joints sealed air tight so no air gets in or out of the box. The woofer is always working in the same mass of air.

2. Ported. A tube is inserted into the box to allow the woofer to breathe. Since the air isn't locked into the chamber, air flows in and out of the tube (aka port). Since the port allows free-air flow, the sub can extend into lower frequencies easier. The longer the port, the lower the tuning frequency of the box. If ported interests you, go to www.linearteam.org and download a program called WinISD. It will help you design the best enclosure for your woofer.

When done right, ported sounds better (this is subjective, but I won't do anything other than ported). The drawbacks of ported are: it requires a bigger box, and it is more difficult to calculate a good box set-up to fit your woofer.

3. Bandpass. A combination of ported and sealed. The woofer sits inside the box so you cannot see it (unless you make part of the box out of plexiglass). The box is divided into 2 chambers, and the woofer is mounted in the wall between the two chambers. One chamber is sealed and the other chamber is ported. This set up automatically eliminates midrange frequencies, and typically will give you a little bit more output than a ported enclosure.
Drawbacks - typically requires a bit more room than ported, and since the woofer is inside the box, you cannot easily hear when the woofer is clipping causing speakers to blow sooner. For the second reason, Bandpass is increasingly becoming a thing of the past.

4. infinite baffle / free-air. The sub is mounted to a baffle wall and there is no box. Many people have done this in the rear deck of their car. Essentially the trunk acts as a huge box for the sub. To get this set-up to sound good, the trunk will need to be sealed off from the rest of the car. All possible spots where air could be exchanged between the car and the trunk should be sealed. You will need to find a woofer that would like a big box to begin with for this to work well. Some companies make free-air woofers specifically designed for this (I have a Pioneer free-air). An obvious benefit is that you can have bass without it taking up much space in your trunk at all.

Have fun!
