## Overview

The BOSS Audio Systems R1004 is a compact yet powerful 4-channel Class A/B car amplifier delivering up to 400W total output. Designed for full range use, it supports both speakers and subwoofers with flexible input options and variable gain control, making it an ideal upgrade for millennial professionals seeking crisp, customizable in-car audio.

## Description

Output - Up to 100W x 4 @ 2 ohm and up to 50W x 4 A/B technology - Class A amplifier flows a vast amount of current to the output transistor even without audio signal reception. Class B amplifier will not flow current to the output transistor when no audio signal is received. FULL RANGE - This full range amplifier can be used not only for speakers, but also subwoofers. Variable Gain Control - Gain control is not a function to adjust the volume. You can only adjust the amount of signal sent from the receiver to the amplifier. LOW & HIGH LEVEL INPUTS - Low level (RCA) inputs are measured by voltage. High level (+/-wire) inputs are measured in watts. Both basically send a signal from the receiver to the amplifier and speaker

Review: イコライザーは付いてないし、w数あってんの？って並にならない。これ買うくらいならアップガレージで中古買った方が全然良い。 安いとはいえ酷い。 音質「ノイズすごい」 安さ「値段同等」 取り敢えず2度と買う事は無い。
Review: 最悪でした。 到着してすぐに取付けたが異音、、、 もう利用したくありません。

## Questions & Answers

**Q: whats rhe size of the amplifier**
A: Dimensions of the R4002 are 10.79" x 10.43" x 2.25".

**Q: I just purchased a BOSS Armor Series 10inch 2200 watt sub and wanted to know if this amp would push it pretty good?**
A: For a few more bucks this is a better match for your sub(SSL EV2.2000 EVOLUTION 2,000-Watt 2-Channel MOSFET Amplifier). Now  with that being said your 10" sub will not handle 2200w it will only handle very short peaks of 2200w and it would have to be clean wattage. this amp will push it well set it about 3/4 and X it over at about 90hz

**Q: Can you support two 10" subs with this one amp?**
A: Hello. Yes, this amplifier will support two subwoofers. You will need to make sure that each subwoofer does not exceed 400 watts peak power.

**Q: will this amp power 2 6x9 500 watt door speakers and 2 rear pillar speakers?**
A: It will with ok sound quality if it's for inside the car listening pleasures. However getting another one and bridging it or a higher powered amp for a good baseline would be recommended.

電源ランプがつかない！ 繋いでも鳴らない！ テスターで測ったら電気が来てない！ 返品でも交換でも海外はめんど〜だし
