Power X 1000W 4 Channel Car Audio Amplifier

I installed this Crunch 4-channel amp to power all four of my door speakers, and it made a huge difference compared to running them off the head unit alone. The sound is much cleaner, vocals are clearer, and the speakers have noticeably more volume without distortion when everything is tuned correctly. Installation was straightforward, and the gain and crossover controls made it easy to dial in the sound. The amp has stayed cool during long drives and has been reliable with no issues so far. For the price, it’s hard to beat. If you’re looking for an affordable 4-channel amp that delivers solid performance and brings your speakers to life, I’d definitely recommend this one.

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 !

One thing to note about this amp is it gets hot and i mean hot so make sure it is well ventilated. i cant really say that i have had any issues with it this amp it has been nice for what i wave used it for. Now if you where me you make an after market cooler for this thing to keep it cooled off better seeing how it get so hot some times you cant even touch it. this amp is easy to install and can keep its own so for the price and the performance it puts out id say its a nice little amp well worth purchasing for beginners

Added this amp to a factory system in a Jeep Patriot. Replaced my stock 6x9’s that are in all 4 doors with some Kenwood 6x9 3 ways. Sounds very good, I ran each speaker on its own channel and it sounds like the speaker can’t handle the power. I’m gonna replace the Kenwood’s with some Rockford’s soon and see if they sound any better. Overall I’m very pleased with the amp, so far I haven’t had any trouble with it overheating or causing any problems but it’s only been installed for two weeks now so hopefully it won’t let me down. For the money, I would buy it again. I would say it’s a pretty cheap upgrade to a factory system that seems to working well.

funciona de maravilla

After a few months of use, I'm changing this rating to 2 stars. The noise on the amp is pretty terrible and it constantly overheats and shuts down at high volumes. This is on a system with 2 320w 6x9s 2 60w midbasses and 2 45w midrange and low power tweeters. If you want something super cheap with noise for moderate volume listening, this will work with a bit of noise. UPDATE 4/2/17- I tried this out running a subwoofer and it's just such a bad amp. 1. I hooked it up in a bridge configuration and it outputs 2 ohms instead of 4. The reading on my multimeter also jumps wildly under load. Just bad. 2. Even at the lowest gain, it shuts itself off. These being said, I've replaced this with an Alpine powerpack for my regular speakers and have experienced no noise or feedback like with this amp. Going to see if I can return it somehow as it's done nothing but waste my time and money in every application I've thrown at it.

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.)

So far so good! I just installed this amp to replace my old dying Jensen amp and everything sounds great. I have it running a set of Focal ISU 165s and it’s clear and crisp. I was able to balance the gain so it doesn’t over power my sub. My only issue I saw was the connections for +12V and Ground are fair small. If you’re running 4 gauge wire or bigger then you may have to trim your connectors like I did.

This is a good product for the price.

Bueno

Cheap amp. Feels cheap, looks cheap, sounds cheap. Not recommended for quality. Gets 3 stars for functionality alone. Disappointed, but it works, what more can you really expect for $80?
