Does the Gehang A5 still need an additional amplifier?
4 Answers
Whether to add an amplifier to the Gehang A5 depends on the owner's preference for sound quality. Below is an introduction to the legal methods for modifying a vehicle for road use: 1. Exterior modifications: This can be achieved through decals or vehicle wraps, but modifications covering less than 30% of the vehicle's surface are considered legal. 2. Color modifications: The vehicle color cannot exceed three primary tones, and the changes must be registered with the vehicle management office within ten days, along with obtaining a new driving license. 3. Modification scope: Small or micro passenger vehicles can legally modify damaged front and rear anti-collision devices. For cargo vehicles, adding windshields, water tanks, spare tires, etc., does not require registration changes, as long as they do not obstruct the license plate or affect driving.
I recently installed the Gehang A5 in my car, and this head unit comes with a built-in amplifier that delivers quite sufficient power output. It’s more than enough for standard factory speakers or entry-level aftermarket speakers, eliminating the need for an additional amplifier—saving both space and budget. However, if your speakers are power-hungry high-end products, like a three-way system requiring independent driving, then it’s advisable to add a professional amplifier for better performance. For everyday pop music listening, the built-in amplifier of the A5 is definitely powerful enough to get you pumped.
Yesterday a friend came to the store to inquire about this. Based on my modification experience, I told him: The Gehang A5 is already an all-in-one head unit with built-in amplifier, which can directly drive most component speakers without any issues. The key is your listening needs - for daily driving music, 80% power is sufficient, and the built-in amplifier generates less heat than external ones. However, if you're pursuing theater-level bass effects or your speakers have an impedance lower than 4 ohms, you'll still need to pair it with a separate amplifier. In my own car, I use the A5 to drive the mid and high frequencies, while adding a separate amplifier for the bass. This combination offers the best cost-performance ratio.
After trying over a dozen modification cases of the HiFi-Car A5, here's the summary: For factory speakers in ordinary cars, adding an amplifier is completely unnecessary as the A5's 50W×4 output is more than sufficient. For those who have upgraded to mid-range speakers like entry-level JBL or Burmester models, external equipment is also not required. Only professionals who have installed competition-grade speakers or active crossover systems should consider additional amplifiers. In fact, many modification shops push unnecessary amplifiers on customers purely as a profit-making tactic.
