: Never connect speaker wires to the car chassis. Mismatched polarity (reversing +/-) will cause "phase cancellation," resulting in weak bass and hollow sound.

Since official manuals can be hard to find, here is the universal installation logic that applies to 90% of Pioneer 4-channel MOSFET amplifiers.
Before diving into the pages of a manual, it is crucial to understand the hardware itself. The term is often searched by users who see this printed on the faceplate of their radio but don't fully grasp the technology behind it. The generic keyword is a trap; the specific model is the key
| Mode | Front Left | Front Right | Rear Left | Rear Right | Min Impedance | | :--- | :--- | :--- | :--- | :--- | :--- | | | Ch A (+) / (-) | Ch B (+) / (-) | Ch C (+) / (-) | Ch D (+) / (-) | 4 Ohms | | Bridged (2 Ch) | Ch A (+) & Ch B (-) | N/A | Ch C (+) & Ch D (-) | N/A | 4 Ohms |
In older or cheaper car stereos, the internal amplifier chips were often IC (Integrated Circuit) based, which could distort the sound at higher volumes and generate excess heat. A Mosfet output stage, however, acts like a high-speed digital switch. It is incredibly efficient.
