## 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: Excellent - Super bien !

## Questions & Answers

**Q: What amp would be best for mtx terminator 2 12**
A: I have the pioneer 1000watt that works good with my terminator 12s.

**Q: Will this work for two 8in pioneer shallow mount subs?**
A: Works fine for my two 10 inch Rockford Fosgate subs.

**Q: using an ipod nano as the input to this amp, will it turn on automatically and will it function properly?**
A: Yes you can. But the output voltage from the nano is a maximum about 1.5 volts. So you would have to run a short RCA to 3.5 adapter for signal loss. Also you will need a switch to power amplifier on and off. I have done it. Also you will have no ability to equalize the sound.

**Q: Will this work for (2) 10 inch rocford fosgate subs**
A: That's actually what I'm using it on. I have two 10 inch P1s and it works well. Both my subs are on a single input and if i try to bridge them, it cuts out so i just use a single channel and it sounds good.

### ⭐⭐⭐⭐⭐ Great amp, with awesome sound and definite value for the money
*by B***H on 26 December 2025*

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!
