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! Review: Perfect for driving a single 8” sub - Paired this with an 8” pioneer sub and alpine deck, bridged mono on the sub outs. With gain at 100% and sub level at full the bass hits hard and clean. You can feel the bass with just 1 8” sub. ## Features - 2-Channel Class A/B Amp – Elevate your car audio with the Pioneer GM-A3702 2-channel amp, delivering louder and clearer sound.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great amp, with awesome sound and definite value for the money *by B***H on December 26, 2025* Sounds really better than expected.
