How to get more bass out of my car stereo?

I drive 2 company cars at my work (Ford FG Ute & Hyundai i Load) & both vehicles would have the best.sound systems found standard in any other car I've driven. Unfortunately I have drive home in my car. I I.installed a Sony 50w x 4 CD that fails to satisfy my appetite for rich, clear deep bass. Do these company vehicles have amps as well? I think not.

WHEN DEALING WITH any FREQUENCIES, BUT ESPESIALLY BASS, SPEAKERS PLAY A huge rOLE. TRY USING THE LAREGEST SPEAKER WITH THE HEAVIEST MAGNET THAT YOU CAN AFFORD AND MOUNT WITH FEW PROBLEMS. ALSO ADDING A GRAPHIC EQUALIZER AND RAISING THE LEVEL OF THE LOWEST FREQUENCY TO A POINT YOU LIKE, SHOULD HANDLE ANY PROBLEM. If MONEY ALLOWS ADDING A woofer(A LARGE ENCLOSED SPEAKER WITH IT'S OWN POWER SYSTEM JUST ABOUT COVERS IT all. BLESS YOU, bAMA bARRY 50.

What you need is a subwoofer my friend. There are a few options but if you want really clear tight bass you need a sealed enclosure subwoofer. The other option is ported (I run ported myself at the moment) ported subs are louder, but often are a little bit sloppier with the bass response and do not sound as clear. That's not to say that ported won't sound good, because it will.

Most factory sound systems won't have separate amplifiers but you will often find they are enough to power the speakers themselves. If you get yourself a subwoofer you can set up what is called a high pass filter, it's an optional setting on any good head unit. What that does is stops your speakers trying to play tbe low frequencies, leaving it to the sub to play. If you try to pump low frequency bass out of your standard speakers they will sound distorted. This high pass filter will remove that distortion and the sub will add the bass. The end result is beautiful sound.
