## Description

2-channel bridge amplifier Pioneer amplifiers automatically select the appropriate input signal mode, cinch or speaker mode. When the receiver is turned on, the amplifier will automatically turn on. When connected to an OEM receiver or receiver without RCA output and using the speaker level output, the amplifier automatically senses the input mode and turns on in sync with the receiver. When connected to an OEM receiver or receiver without RCA output via a speaker cable, the amplifier will be switched on at the same time as the receiver. Pioneer amplifiers automatically detect input signal and select RCA level or speaker level.

Review: Clean sound, no alternator whine - Previously I had a Crunch amp and it gives the alternator whine when I press on the accelerator. Tried many ways to fix it with capacitors and better grounding but it can only be fixed by turning down gain all the way. After changing to this, it sounds really clean even with the gain being turned up by default, despite having reused all the old power and grounding cables.
Review: Great amp, with awesome sound and definite value for the money - Sounds really better than expected. Looks great and inconspicuous. I have mine wired at 2ohms. It holds stable with no drain and no overheating. Easy to connect and the auto on/off feature is great. You'll really enjoy this amp. It provides a great sound over stock any day. And if we're being honest, i actually bought 2!
