Line Level And Speaker Level Inputs
(Low and High Level Inputs)
The R1004 has two different ways that you can get a signal into it.
One is called Low level input and the other is called High level input.
A low level input is measured in voltages. It comes in the form of RCA outputs from the back of your receiver and goes to the RCA inputs on your amplifier.
A high level input is measure in wattages. It comes in the form one positive and one negative wire from the back of your receiver to and goes to the input terminal of your amplifier in the same wire form.
Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance.
NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier a

Variable Gain Control
Properly setting the gain on your amplifier is key to getting great sound in your car.
The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier.
If you set it too high, you are introducing distortion into the sound. But if you set it too low, then you are choking back on what the amplifier is there to do in the first place.
Here is a technique that works on most amplifiers.
First, turn the amplifier’s gain all the way down. Then go up front and put on some music. Now crank the stereos volume until you hear distortion. Then back it off until the distortion goes away.
Go to your amplifier and turn the gain up until the distortion comes back. Then once again, back off until the distortion goes way.
And you are done!

They DO tell you the true RMS @ _ Ohm ratings of it in the manual and fine print but the packaging and box does the usual flea market audio trick...you know, the whole overrating the power output. Throwing 15000 Watts at you for $30...Yeah, that thing.
I would NEVER use this with a woofer of any kind. It does a noticeably better job than my Alpine headunit for powering the front and rear speakers but that's about all I would recommend doing with it. The amp performs well under a seat and I haven't noticed it getting unusually hot or any cut outs. It's quite small which is nice for tight fits. It's comparable in size to a typical factory amp.
I did notice that Amazon claims it has a remote subwoofer level control... Well, I didn't notice anything like that in the box. Not a big loss.
At the end of the day, it's a $30 amp. It'll do a better job powering your mids than your headunit or factory amp but that's all it's good for. Good little amp for the money. Nothing more. Nothing less.
I still have a lot of faith in Boss being a great choice for a system on the cheap for a work vehicle or your wife/kids car. My entire setup is Boss besides the subs. Even the cabling. This amp is outclassed by everything else and I half expect it to say "Pyramid" if I pried off the shroud. I've lost a little faith in you Boss....

Powered my two 8" OEM subs.
Pictures in the description are not this model. They are tricking you on purpose. The R1004 has less feature than that of the pics.
Ok not name brand and not the highest output but sounds way better than stock. For the price, why not get it.Published 2 months ago by lawrence l.
