I was talking to a friend of mine and he advised me to run my 6x9's through a small amp, same with my front splitters..I don't know much about it and before I go and spend my cash I just wanted to know if its a good idea?

Speakers do benefit from and amp as long as they are designed to take it..

If we are talking about stock Mitsubishi/Eurovox speakers then no, its not really recommended.

An amplifier boosts the signals from the head unit allowing the speakers to reproduce the same signal with less effort.
Allowing it to play louder and cleaner then off the tiny inbuilt amp in the head unit..

So an amplifier can bring more volume and clarity to your system..

There is heap of technical jargon I could spit out explaining why its not a good idea on a stock system and why it is a good idea on aftermarket gear but if you could provide a little more detail on what your current audio system is, will help us explore this option
further.

A normal aftermarket headunit will be rated at around 54W PMPO. This is what it can handle for a few milliseconds before dying. Normally they would put out around 16-18W RMS which is it's continuous rating. So the output from them headunits is very low.
The second problem is they are built to a very tight budget so have a low current output and their distortion and noise levels are not real flash.

So if you buy an amp (Response from Jaycar are fantastic bang for your buck at the budget end) then the above issues are greatly lessened.
More current output will enable to amp to be able to move the speaker with more control, bass and midbass will be tighter, deeper. Treble will be sharper due to the lowered noise.

All in all, if you have the money a good investment. Don't forget to factor in around $150-$200 for cabling and a fuse.

As magnat said though, don't waste your money if you just have the stock speakers...

Totally agree with everything that has been said :D

I didn't realise how bad speakers sound off a headunit until I went to crank some 6x9's in a mates car running off the headunit. End result - poor.

For $200 ( provided you can install it yourself ) you can get a nice little 2x 50WRMS+ amp ready to run most aftermarket speakers.

Hell from Jaycar you can get a 4x50wrms amp for $150
or
A 2x80wrms amp for $170-$180

It depends on how the system is set up..
My system has no Amp running the fronts and rears but I do have one powering the subs..

It also helps to have a deck with a sub out... Remove all the Bass from the Interior speakers and let the sub handle that.
End result can be suprising... Although in saying that, the difference with an Amp would be a benefit.

+1 It is suprising what difference 3 sets of rca outputs have over 2

Yes the ability to control the sub off the deck is worth the extra..
I mean these days even a $249 JVC deck has sub out...
