This guide will help you make informed choices as far as buying a car radio and CD players are concerned.
1) Replace your existing radio with an in-dash cassette-radio, CD-radio or CD/MP3-radio:
If having a multi-disc changer is not a priority then an in-dash cassette-radio, CD-radio or CD/MP3-radio may be your best option, producing the best overall sound. If your car has steering wheel radio controls, these can remain fully functional with the aid of readily available installation accessories. A harness adaptor and/or fascia adaptor may also be needed if your car does not have standard (ISO) fitments.

If you are thinking of replacing or upgrading your original factory fitted car radio but are unsure of the options, benefits and technical considerations, then read on, all will be explained.
Factory-fitted radios (standard fit radios) in the past had relatively low power outputs of about 3 to 5 watts RMS. However, the latest factory-fitted radios have improved vastly with power outputs of up to 100 Watts. These figures represent 25 Watts, ‘peak’ power per channel x 4 (this basically means x 4 speakers).

I have been to a lot of car audio shops that use test lights, and not as many that use digital multimeters. Is one really “better” than the other for finding power sources?
Absolutely! A test light looks like a screwdriver with a sharp pointed end, and consist of a small bulb and a grounding wire or cable. It works by grounding the bulb, and once it comes in contact with a power source, it will complete the circuit and light the bulb. This is the easiest way to test power because the bulb either lights up for power or doesn’t if their isn’t any power.

Car audio installation is a fairly specialized job, requiring at least some knowledge about the basics of car designs and electronics. The final audio output depends to a large extent on good installation. You may buy the best equipment, but if it is not properly installed, then the result will be poor. The entire set up consisting of wires, amplifiers, alternators, and speakers would have to be perfectly set up for that great audio effect.

Battery isolators are those alternator and trouble saving devices that separate your primary battery system from your auxiliary battery. Most people run their amplifiers and added accessories from a secondary amp to lighten the load on other factory installed devices. Here is a look at how they work and why they are important.
The diode based isolators are basically two high current diodes. These diode isolators are known for their durability and long life, and seldom fail. They do however sacrifice a little power due to the 0.5 volt drop of the incoming charge. This voltage drop will keep the battery from reaching maximum charge, but will allow it to maintain a high enough charge during peak use to keep your headlights and other devices from dimming, and power your amplifiers and added accessories.
