This amp .(cheap) 2 pioneer 8" MIDBASS speakers in backseat (mid price ranged ) 2 mid price ranged component speakers front door . All four speakers powered by this amp. Music sounds larger than freaking life. So loud you can lose your hearing . . . Also no distortion whatsoever. I just recommend buying this amp . Butbif you do . With the money you save . Spend it on better speakers . You can go cheaper with amplifiers . But not with speakers . Use the setup I have mentioned above . Out a single 8" 10" or 12" in the back With a mononamp of about 1500 or 2000 watts as well . And you'll have a sound system for 500 dollars , that I'll out against a 4000$ system any local audio shop charges. If you hear my advice . (In the past I was a sucker buying brand name amp everything) There's no need . They put out power .it's your speakers that make it sound good or not. And remember if you listen to radio Total harmonic distortion andnaol that B.S expensive Amps brag about DOES NOT MATTER! Your music input mp3's are not studio quality . Or high definition. Your FM radio is not DVD or CD quality. Your spliting hairs buying a 700 dollar 4 channel amp . This does just fine. It puts massive power to speakers . Quite surprised how well it works actually . I went from a 2000watt more expensive amp down to this 1000 watt more simple amp . And I like this sound better Your welcome . And sytem planning is KEY. Mine is . Two Nice components up front for highs . (Don't cheap out) but don't get most expensive either . Two Pioneer 8" MIDBASS in the backseat . They make a 6 and a 1/2 as well . Their Amazing neither this amp . I bridged those . And in trunk a single 12" with a 2000 watt mono amp . (Once again , didn't buy an expensive mono amp . No need Just needed to put alot of electricity through a wire . Not bake me dinner ) And the stereo for roughly 500$ sounds like A 4000$ stereo a local car audio shop would charge you for . Unebelivably crisp at all volumes low and high. no crackling at high volumes . It goes as loud as your ear can physically stand and more all while being clear . Inr commend the setup mentioned above. I planned it to be a cheap stereo that sound like it cost ten times more Better than any new stock radio in a Jew infinity of Lexus . Better than Bose steroes in new cars . Or beats by DRE systems. Enjoy !

East to install, most of the information you need is provided in the pamflet you get. As a beginner who has not installed an amplifier before it took me and a friend about 6 hours from start to finish. With common tools, and a crimper which I would not consider a common tool. I took the power from a positive battery terminal, the ground from under the seat, the REM was easy to find as the previous owner had left a cut off tail and I spliced into that. I only plugged in the RCA since I am do not know enough about the HI in cables. Some of the things I'd recommend buying at shown in the pages of things other people have purchased, a decent set of crimpers isn't needed but would make your handwork look alot nicer. A power delivery kit that included a power cable, a ground, as well as a REM cable and the quality was as expected. I also purchased 50ft of speaker wire which was too much for my application.

Wired it up just fine, sounded great for the first day it was active. The following day we went to go grocery shopping, came back to the car, started it up and the speakers made a horrible screeching noise. After that the audio quality became horrible and after we got home now it stays in protect mode. Gain set correctly, 8ga power wire, sufficiently cleaned and sanded down verified ground, still wont come out of protect mode. Switched out with a known good amp and that one works fine. This crunch amp definitely burned something up as it smells bad near the controls. Pretty disappointed. Was able to get a refund through Amazon Customer Service.

Ok I bought this about a year ago or so and I haven’t had any problems with it I’m currently running 4 door speakers and 2 6x9s at full capacity at all times and never had a issue with protection mode or anything like that definitely recommend

Crunch is another Chinese based company that produces low quality amps with incredibly over-hyped spec charts at low prices. A rule to follow with these is you get what you pay for. For $60, I got the PX1000.4 with the intention of powering my door speakers. (4x Rockford Fosgate Punch 6.5s). This does drive them, but does have its fair share of issues that, after a year of use, is leading to me to purchase an amp to replace this one. First off the power rating is grossly over spec'd. With only 60w of amp fusing, only lends this amp to produce around 500-550w at 2ohms. At 4ohms, you only be getting around 75w per channel. Which IS enough to power most speakers. However this leads to the second issue. Wired at 4 ohms and running this with 1 speaker occupying each channel, I can only run this amp at capacity for roughly 15 minutes before it overheats and enters protection mode. Heat dissipation is essentially non existent. Lowing the volume to around 60%, I can generally get it to stay on, but lets be honest, If I've put in money to increase volume and fidelity in my system, I don't want to be listening at 60% unless I'm trying to carry on a conversation in my vehicle. Overall, I'd grade this a "highschooler special". Its cheap, does provide power for speakers and if installed and tuned properly can serve a purpose. Just don't expect this to do any more than the bare minimum. TLDR rebranded BOSS amp (P.S. the terminals are absolutely horrible.)
