Used Car Audio System Test

The people who are educated and experienced in used car buying know about the importance of test drive of a vehicle before they are purchasing. Some people even thoroughly inspected the vehicle by a professional mechanic. A certified pre-owned checklist is offering by the manufacturers through online. Very rarely a used car buyers just turn on the audio system only to check for working or not. To listen the unusual sounds from drive-train or engine usually buyers turn off the audio system. If you are interested for the audio system in the car when you are off the wheels, and wants to test the audio system to do not disappoint later, follow these steps. It do not require any special tools, by paying attention to the stereo system for a few minutes you can estimate the condition and the performance of the audio components with your ears and eyes.

• Telltale signs check: You need to check for some components in the used car's audio system to know about the quality. You can identify whether there is any different or aftermarket audio system was installed in the vehicle by looking at wiring for speakers and amplifiers that have been left behind. Some people use low quality or inexpensive equipment to fill the holes left by previous equipment. Look for the mismatched speakers or improperly fitting car stereo. If you are suspected that the vehicle audio system was previously installed, you may want to see in the trunk, under the dash and behind the trim panels for possible damage to the vehicle. The metal panels many cut to install the large speakers, the unplugged screw holes may cause leak fumes or water into the car. To know the condition and age of the speakers look at them from either inside the trunk or through the grilles. The speakers installed in the door are susceptible to water damage, and the rear speakers to sun exposure. Check for any material fall from speakers, and small, brittle pieces of foam.

• Sound Check: Check the radio is properly tunes in the stations. You can check any engine related noises coming through the speakers by start the engine. If you hear sounds, ticking or whining is change with the engine rpm. Defective component or poor wiring may cause this. Next, listen with your familiar music as with louder volume while driving and normal volume while parked to check the system performance on the road noise.

• Visual check: Check the radio antenna while checking interior for any signs of hanging on or missing or broken. If it is power antenna, check the working condition. Check the speaker grilles, speakers and radio is at the right place, any parts are missing, poorly installed. Some owners and most of the dealers are preferred for factory appearance of a used car, so they remove the aftermarket sound system or any other components from the vehicle.

• Systematic approach: First power up the head unit. Verify it crates sound and check the power antenna operating properly. Check the radio functions like scan and seek. Check the speakers at normal volume individually. Check the system by fading the way to rear and move balance from left to right and right to left, then fade to front and repeat the same process.

The problems you find from this may not effect on the buying decision whether to buy or not. However, you can negotiate the price up to the repairs or ask for discounts from a dealership.
