I am no expert of installing Car Audio, but I bought a Nice little car android with touch screen and the installation was not that clear, so It wasn't just a plug and play in by Fiat Abarth 500 with the beats Subwoofer, however I managed to connect my speakers direct without the beats amplifier and the sound was crap, however I got on this amplifier and bought it with the expectants to be able to improve the sound and use my Sub woofer. And it worked perfect. i used the high in not the phono plugs and it just worked great. Yes I did see some one saying on the reviews that it does get hot, but as long as you give some some ventilation it is OK. It is running all my 4 speakers and my OEM factory subwoofer. Instructions simple to follow. All I would add is if you detail what is in the box, you would have saved me $20 from not buying the two 4 pin plugs for the high input. These do come in the package.

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.

The one star reviews on this product are from people who either got a dud or who are too amateur to know how to install a speaker system. Is this amp cheap? Yes. Is it going to power a King Kong sound system? No. But it’s fantastic for budget builds. I have 2 6.5 speakers, 2 4 inch speakers and a 10 inch subwoofer in a clapped out Volkswagen. It’s gone into protection mode. I traced my wires and fixed the problems, and it’s come back to life every time. I had a soft top leak and this amp got wet. It wouldn’t turn on. It sat out in the sun for eight hours and came right back to life. This amp is a beast. It’s hardy, and if you get a good one it’s going to last. If you want to get a warranty and customer service with your purchase maybe look elsewhere? But if you want to shake your trunk a little and get a taste of how an amplified sound system hits, the crunch is your answer. Plus it comes with some decent stickers. Don’t push it too hard and it’ll be nothing but a good time.

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.

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.)
