Product Details

BOSS R1004 RIOT 400 Watt 4 Channel Car Audio Amplifier

If you're still using your head unit for amplification, you have no idea what you're missing! Head units are often unable to provide the loud, dynamic sound you want, and can distort (or even damage) your speakers at even medium volume levels.

That's where the BOSS RIOT Series of amplifiers comes in. Tried-and-true Class AB amplifier topology, 2-ohm stable (for powering a pair of 4-ohm speakers off a single channel), and way more than enough power for even the hungriest door, dash, or deck speaker.

BOSS built the RIOT Series amplifiers with advanced features that are usually associated with amplifiers at more than twice the price: thermal and short circuit protection, soft turn-on circuit, remote turn-on/off, nickel-plated low-level and high-level inputs, LED power and protection indicators, all housed in a stealth black anodized aluminum chassis. Mounting hardware included.

Specifications: • Power output: 4 x 50W RMS (@ 4 ohms), 4 x 100W max (@ 2 ohms) • Frequency response: 12 to 22,000 Hz • Signal-to-ratio: 90 dB • Total harmonic distortion: 0.01% @ RMS power output • Dimensions (L x H x W): 9" x 2.0625" x 10.625".

BOSS R1004 RIOT 400 Watt 4 Channel Car Audio Amplifier

I need to know if this setup will work with a BOSS R1004 RIOT amp: 30 watt 4 ohm speaker + 40 watt 4 ohm speak on channel 1; 30 watt 4 ohm speaker + 40 watt 4 ohm speak on channel 2; 150 watt 4 ohm subwoofer on channels 3 + 4 bridged?

Asked by: epk1
This amplifier is not bridgeable so that would not work.

what input connector is used when having to convert the older 2 wire speaker system to plug into amp. boss 400?

Asked by: jjhall
There are two small wire harnesses that are included with the amplifier in order to use the high level inputs. If you no longer have these you will have to contact Boss to see about getting replacements.

How many fuses and what are the ratings of ALL of the fuses in this amp?

Asked by: cwhite
This has one 15A fuse.

What gauge power wire does this require and what kind of draw would this be on a motorcycle charging system< Would there be a heat issue if mounted in a saddle bag>

Asked by: Rich from Adrian
The fuse in the amplifier is rated for 15 amps, so a continuous draw would be less than this. Heat will be determined by the impedance load on the amplifier. If 4 ohm speakers are used on each of the channels the amplifier should only get warm to the touch. I would recommend 8 gauge power cable for this.

I was looking to power 2 6x9s that were given to me. They say 100 watt RMS at 4ohms each. What would be best

Asked by: Alex662
Any 2-channel car amplifier that is between 75-125 watts RMS at 4 ohms will work for this application.
