The basic components of a high-quality automobile stereo system are an AM/FM tuner, a CD player, an amplifier (optional but recommended) and also good speakers.
Rule: No automobile audio can equal the performance of good home equipment. The auto compartment is little, surrounded with traffic and engine sounds, and surrounded with competing electrical signs. And all of this at a moving atmosphere. A welter of technical and individual choices dictate the last package.
Car audio components are often disregarded. Check mail-order houses and the Internet for the very best buys.
Crucial: Deal with reputable companies and purchase name brands. Make sure you can swap or return parts in case they prove incompatible or do not fit in the vehicle. Bear in mind every unit has to be installed and may require custom mounting accessories. Keep personal tastes in mind. Rock and country music fans typically prefer stronger bass ranges. Classical music requires good mid and treble.
How to allocate your spending: 40% to 50 percent for tuner/tape participant, 25% to 30 percent for amplifier, 25% to 30 percent for speakers (unlike residence equipment, for which half the recommended cost may opt for speakers alone).
General recommendations: Components are a better bargain than manufacturer-installed original audio equipment. Great manufacturer-installed equipment can cost $1,000, a cost that will typically bring you much better noise if spent on components. Try to find a dealer that’s put a sound room to hear and compare different systems.
Under-dash components are easily installed.
Overriding disadvantage: A thief can slide out the under-dash gear as easily as an ashtray. Choose in-dash tuner/CD players if you don’t would like to store the components in the trunk each time you leave the vehicle. (In case you still want an under-dash system, Sony parts are elite ones )
Amplifiers: Most auto-sound packs gain from amplifiers that reinforce bass and high-treble tones.
Problems: Amplifiers are bulky and frequently need to be installed under a seat or in the back. Unless your tuner includes a bypass circuit permitting one to plug into the preamplifier, your pricey amplifier is only going to boost the twisted output of the built-in amplifier.
Goal: Around 5 watts per channel at 1% less or distortion. To get this, the amplifier may need 50 watts per channel because few operate at greater than 10% efficiency in a car.
Bi-amplifiers: They provide separate power boosts for bass and treble ranges. Bi-amplification could be called for if separate bass and treble speakers are set up.
Speakers: Speakers must be compatible with amplifiers. Their power capacity should be marginally higher than amplifier. Case in point: Get 60w speakers for a 50w /ch amplifier. One way to be certain of speaker/amplifier compatibility is to purchase them as a bundle.
Many fans choose four. Non-directional bass speakers will be best placed in the factory cutouts in the back window shelf. Next best placement: In back doors. 15 inch subwoofer can be mounted in front door panels under dash.
