If you want to achieve high-quality sound in your car, then you cannot do without a subwoofer, popularly just a “sub”. It reproduces low frequencies and thus creates bass.
Instructions
Step 1
Many reputable publications test different brands of subwoofers and talk about the pros and cons. favorites are expensive manufacturers such as KENWOOD, PIONEER. If you do not have a lot of funds, then you should adhere to one rule. The price of your car's acoustics should not exceed 20% of the cost of the car itself.
Step 2
Subwoofers are of 2 types: active and passive. Active subs have a built-in amplifier, which saves you the trouble of spending money on an amplifier. Such a subwoofer is connected directly to the head unit (radio tape recorder). You do not need to make connections: radio tape recorder - amplifier - subwoofer. But, of course, they have their drawbacks. Active subwoofers are made from cheaper materials than passive subwoofers and the sound quality is reduced. An earlier breakdown is also likely.
Step 3
In order to connect a passive subwoofer, you need to select an amplifier. It gives at the bridge connection the power, which is indicated in the passport "saba" as nominal.
Step 4
There are 4 types of subwoofers: 1. A closed-type subwoofer with a sealed enclosure.
2. Bass reflex subwoofer. Has a kind of pipe or "cheek" for adjusting low-frequency characteristics.
3. Band-pass subwoofer. The speaker is retracted inside the case, and the sound is reproduced through the bass reflex.
4. Subwoofer with passive radiator (has a second speaker). It is necessary to lower the overall resonant frequency. Subwoofers of the second type reproduce bass better than the "subs" of the first type, but are correspondingly more expensive. The third type is good because it helps to do without crossovers. Subwoofers with a passive radiator are rarely used, as they require jewelry tuning.
Step 5
When you have chosen a subwoofer, do not install it yourself. Contact a specialized service, as the correct installation of the "sub" and the correct connection is a very important component. The sound quality depends on it.
