How to Connect Car Audio?
2 Answers
Connect in parallel with the two 6-inch speakers on the front doors, with the white wire connected to the right front speaker. The gray wire is connected to the left front speaker. Cannot directly drive the subwoofer. If the subwoofer has an amplifier inside, you can add a low-frequency line to the RCA interface.
I managed to connect my car audio system by myself a few days ago, and it felt quite straightforward. First, I disconnected the negative terminal of the battery to prevent electric shock, using just basic tools like a screwdriver and wire strippers. After removing the old head unit, I connected the new head unit wires to the speaker terminals according to the manual—making sure not to mix up the positive and negative to avoid poor sound quality. Then, I securely connected the power and ground wires and wrapped them with electrical tape to prevent short circuits. Bluetooth pairing was a breeze—just search for the car audio name in the phone settings and connect with one click. If installing a rear amplifier, remember to use impedance-matched cables to reduce buzzing noise. Don’t skimp on tools; there are plenty of practical video tutorials online. After finishing, test the sound and adjust the bass and treble settings for a better music experience while driving. The whole DIY process took half a day—saving money and enjoying the sense of accomplishment.
