It's almost the end of the year. Of course, many people choose to return home or return to their hometowns during the long holiday. I am one of them who will return home to their hometown. The advantage of a house in the province is that it is more rural, with rice fields, farms, and many houses. So we can have our own private space. We can sing and dance all night long comfortably without anyone disturbing us. So I thought I wanted a really loud audio system to listen to. Today I will DIY a mid-high car audio system, stuff it in a cabinet, and play it outside the car. Let's see how it looks and sounds. I will purchase all the equipment that I will install from online stores. After choosing for a while, I decided on this set. This is a mid-twee set. There will be 1 amp, 1 preamp, 4 mid-range speakers, and 4 tweeters. They will sell it as a set of 10 pieces, which will be a set of Intree Lek brand. Of course, if we order a set, they will arrange it for us. The price will be cheaper than choosing individual pieces. If you are going to buy, I recommend choosing a set, it will be more economical. ---------------------------------------- Unboxing Review ---------------------------------------- Here it is, I ordered it for a few days. Unboxing it, they will wrap it very well with bubble wrap. There is a tweeter cover. I'm not sure about this box. Oh, the side is the amp. The amp drives 4 Ch, Class AB, flat size, yellow, general standard. As for the small box, this should be the preamp. That's right, a 7-brand preamp with independent subwoofer adjustment. This box will be a 6.5-inch mid-range speaker, two in each box. This is the same. This box will be a tweeter. The equipment that I received is a total of 10 pieces. Received all the items. Let's look at the tweeter. They will use a plate tweeter. This type of tweeter sounds quite clear. The magnet is large and the edge is made of metal. When you lift it, it is quite heavy and usable. But when we use it, we will connect the tweeter to the mid-range speaker, right? So they will include a C signal filter. I will not use the cover that they include. But if you want to install it in your car without drilling holes in the door panel, you can place the plate tweeter on a stand like this. But if you drill a hole, the stand will be useless and you will not need to use it. This is a 6.5-inch, 4-ohm mid-range speaker with the Intree Lek brand printed on both the front and back. The next one is the preamplifier, which is paired with the amp. Many beginners have asked if it can be used only as a preamp to drive speakers. The answer is no, because the preamplifier does not have a high power amplifier. The preamplifier is only for adjusting the tone. You want any frequency to be prominent or dropped. We will adjust this part, like this button, it is a low tone of 50hz and then gradually increases to 125H, 300, 700, 2 thousand, 6 thousand, and 12,000. The frequency will increase continuously. Along with the Master volume, the gain can be increased or decreased from this point. Most importantly, the pre-amp has multiple output sets, can separate the sound into front and rear pairs, including the subwoofer, totaling up to 6 CH. This pre-amp also has independent subwoofer adjustment. This is its advantage. As for the amp, as I said, most mid-treble drivers will still use class AB because the sound details will be quite clear. Connect to general 4 ohm speakers with RMS 40w per CH. But it can be connected in 3 formats. The first format is to connect each CH, 4 speakers are 4 CH. The first 2 CHs are connected normally, but the last 2 CHs are bridged, combined into a single CH to get more driving power. As for the third format, both are bridged. Simply put, if there are 2 4-ohm mid-range speakers connected, it will be 2ohms, 2ohms. They can be connected in bridge mode by connecting 1 speaker cable per CH. The advantage of bridge mode is that it saves wires. It will use less wires. Because we just drag two speaker wires, the speakers at the end of the wire will be parallel, whichever way, we will separate later. But for me who has tried testing both bridged and non-bridged, try listening with my ears. This is my personal opinion. I think the non-bridged one has better sound. It may waste a bit of wire, but it gives better sound. I think it's worth it. If you notice, the bridge type must be a letter below, with + and - below. But if it's not bridged, it's plus and minus above. Normal. Thank you to all friends who follow and watch. 6.5 inches, 4-inch tweeter, is a car mid-range speaker set.
