A1: The DSP power amplifier is non-destructively installed. It can enhance the sound field of original car, and the intelligent sound processor that improves the sound quality of the original car, with its own power amplifier function. Q2: Is it troublesome to install? Do I have to connect a lot of wires? How do I use it? A2: The installation is very simple. It does not damage any lines of the original car or the host, just plug it directly with the original car line. For the specific use of the tutorial tuning technology, please refer to the above official website Q3: After installing the power amplifier, how will the sound quality of the original car be improved? A3: After installing the power amplifier, you will feel comfortable, full and rich stereo sound. Through the DSP delay processing, you can raise the overall sound field of your car, parallel to your ears, to get the best listening experience, instead of making a dull and annoying sound under your feet like the original car stereo. Q4: My original car has been changed to an imported high-power speaker. Can it drive the speaker after installing a power amplifier? A4: Of course, PUZU automotive DSP amplifier uses high-power chips, with a maximum power output of 4x150W, which can fully meet your requirements. Q5: What should I do if I can’t tune? A5: Our DSP has both automatic and manual tuning functions. If you do not know how to tune, you can use our built-in mode. If you are more interested in tuning, you can refer to the video on our official website for tuning. The tuning steps are simple and easy to understand. For a brief description of audio segment, buyers can adjust according to the instructions (for reference only): – Subwoofer: 20Hz-40Hz, when appropriate, the sound is strong and powerful, and can control the sound of thunder, bass drum, pipe organ and bass. Excessive boost will make the music muddy. Bass: 40Hz-150Hz, is the basic part of the sound, its energy accounts for 70% of the entire audio energy, is an important component of the performance of the music style. When appropriate, the bass is relaxed, the sound is full and soft, the sound is thin when it is insufficient, and 150Hz is excessive The increase will make the sound dull, the brightness will decrease, and the nasal sound will increase. Mid-bass: 150Hz-500Hz, which is the structural part of the sound. The vocal is located in this position. When it is insufficient, the singing vocals will be submerged, and the sound will be soft and weak. When properly raised, it will feel thick and powerful. Excessive raising will seriously affect the clarity of the sound. Degree – Midrange: 500Hz-2Khz, including the low-order harmonics and overtones of most instruments. It is the characteristic sound of snare drums and percussion instruments. When appropriate, the sound is transparent and bright, and when it is insufficient, the sound is dim. Excessive boosting will produce a sound similar to a telephone. Middle and high pitch: 2KHz-5KHz, it is a special modifier for orchestral instruments the rubbing sound of the bow and the string of the string, the sound of the finger touching the string of the plucked music, etc. The sound penetration will decrease when it is not enough, and when it is too strong, it will Masking the recognition of language syllables. Treble: 7KHz-8KHz, it is the frequency that affects the sense of sound hierarchy. Excessive boosting will make the piccolo and flute sound prominent, and the tooth tone of the language will be aggravated and the tone will be unclear. Extremely high pitch: 8KHz-10KHz, when appropriate, the metal sense of the triangle iron and the stand have high permeability, and the rhythm of the sand clock is clear and recognizable. Excessive boosting will make the sound unnatural, harsh and easy to burn the high-frequency speaker unit. A balanced and pleasant sound should be: – Below 150Hz (bass) should be full, soft and flexible; – 150Hz-500Hz (mid-bass) should be thick and powerful without turbidity; – 500Hz-5KHz (mid-high tone) should be bright and transparent but not rigid; – Above 5KHz (treble) should be slender, round and not sharp. The whole frequency characteristic is flat: the sound is naturally full and flexible, with distinct layers. When the frequency response is windy: the sound is rough and turbid, the high pitch is harsh and hairy, and there is no layering, and feedback screaming is easy to occur when the sound is amplified. More Details: – HD sound quality processing chip – Wide diameter filter pole – Super capacitor – Regular circuit layout – Premium chip Question & Answer: 1. Can I install an amplifier in my car? 98% of the models on the market can be installed, please contact customer service for specific models. Please note the model, year, displacement configuration, etc. When placing an order. We use the special wiring harness that is matched with the original car, which is non-destructive installation, just plug in directly. How is the boost effect? Can I install an amplifier in a car that has changed its horn? After the original car audio equipment is installed, the overall sound quality can be significantly improved. After installation, the treble is clear and bright, the bass is strong and powerful, and the overall sound quality has been significantly improved. After changing the speaker (set coaxial speaker), the effect is significantly improved, and the sound effect shows a qualitative change. The supporting use of the speaker and DSP will complement each other. All products do not include installation costs. Car owners with strong hands-on ability can install them in accordance with the instructions of the manual; or go to the car beauty shop or navigation modification shop outside to install it.
