R2504 Riot Series Car Audio Stereo Subwoofer Amplifier - 1000 High Output, 4 Channel, Class A/B, 2/4 Ohm, High/Low Level Inputs, High/Low Pass Crossover, Bridgeable, Full Range

I bought this because I was not happy with my new JVC stereo- it did not have the power my old JVC did. Come to find out the old JVC's have a great pre-amp that the new ones lack. I still have old JVC as I still go back and forth about switching it out- only thing that stops me is new has a usb port in front that I use all the time. I bought the amp to power 4 speakers in my 02 Chevy Silverado 1500 ext cab. I have it powering four Pyramid 250 watt (each) speakers- 2 are 5x8's and 2 are 6x9's. It does a great job of boosting the midrange and highs. I went from having to turn my stereo to 16 to get a decent sound level for driving to only turning it to 3 to get the same level now. I have another Boss amp (1200 watt) hooked to my subwoofer. I will say the subwoofer control is not going to boost your sub...it will actually cut power to it. It is nice if you have someone in the vehicle that hates a lot of bass, but other than that I leave it unplugged. What some people do not realize is you have to match watts for watts. If you are trying to run 1000 watt amp to power a 800 watt sub- you will not be happy. It will get hot unless you limit the output. I had that issue when changing to a lower watt sub, the amp would get hot and turn off (I thought it was the sub turning off). I had the audio shop make some changes and now all runs cool and the music is great- OK except to the old people who can't stand the thumps and loud music coming from my truck :)

The amp so far is making my speakers 🔊 work nice and loud and hard. Boss been around forever and the brand is good. No complaints on my end and the price was good . I would recommend

Don't squeeze it very hard, it'll break inside.

I have only been running this amp for about two weeks, but it has performed up to expectations. I'm using it to power four 4-ohm Alpine SPS-6000 (Type-E) speakers which have an RMS of 60w each. It's all I need, even too much, for this purpose. The best feature this amp has in my opinion is the built-in crossover. Prior to this amp, I had a really, really cheap amp with no high pass filter of any kind, but now that I can keep any bass notes from going to my speakers, they are much clearer. Overall a good amp -- you get what you pay for. For mid-range interior speakers, it works well.

Giving it 3 stars because its easy to install but im unable to get whining noise out even running a LOC with RCA cables. It minimized the noice but its still present.. Will be replacing it with a more higher end

Excelente

I bought this one and another one from the same manufacturer. The first one was installed and was absolute garbage! Boss claims are just flat out lies... and BIG ones at that! You will get around 10% of what the claims are ... so, you've been warned! Google Boss amplifiers dyno tests ... they are a joke. But... I didn't find it too funny after spending a ton of time installing the first one I got to find out that I was a total sucker! This particular amp was not even installed because of the quality, sound and output of the first one I got scammed on. I would not recommend this amp to anyone! Run for the hills ... you could pretty much blindly and randomly pick any other amp on amazon and I'm sure you would have better luck! DO NOT BUY.

I would recommend these, lowered amp volume, maxed my radio, EQ and crossover a the adjusted amp volume to my preferred 'maxed' volume which for was 1/3 amp imput volume. Depending on the selections on the amp it may sound like only two channel are playing. If you hear feedback sound from this amp it is not the amp it's your wiring or alternator. Turned high pass only since i have a dedicated sun and amp tandem. There's enough power in this amp to run a 1k rms sub for sure. Fuse are 25w/2channels.
