Guandao audio modification German Rekal speaker sharing fever audio modification requires eliminating the complexity and simplifying it
Car audio modification must be reasonably matched, knowing how to simplify the complexity. The obstacle caused by blindly piling up various equipment is the loss of power and increasing the burden on the system. Beginning audio enthusiasts think that the more equipment is installed, the effect will be better. In fact, if the modification is good, the effect will naturally be good. This time, we modified this Honda Crown Road, and its scheme matching is extremely simple. Every piece of equipment is independent, which is in the same strain as the system music style.

System modification scheme list:
1 Original main engine
2 Front sound field: German Rekal (formerly Rainbow) PL professional series two-way frequency
3 Super bass: German zero point 8-inch cabinet customization
4 Front sound field power amplifier: German zero point four-channel sound quality power amplifier UA 4.150 SQ
5 Subwoofer power amplifier: German Zero Point IW 2080 HPX-II
6 Wire: Barney/Magic Sound
7 Power supply: American Stinger audio special battery

In the modified detailed renderings, the tweeter mold retains the essence of the log, and it looks very textured when matched with the metal outer ring of the tweeter unit. The simple and low-key style also matches the owner’s personality.
