Best amp for the price
I love the product i accidentally requested for a return but it was my radio not being on for the amp to turn on. Everything is fine and works great!! Ty!!
Verified purchase
Best bang for your buck
I ran this amp on 4 8s for 8 to 9 hours straight for 2 days in a row,they never cut off and have plenty power
Verified purchase
Pretty nice amp for the money !
I find the Crunch PZX1800.4 aesthetically pleasing to the eye,it's candy apple red chassis has a glossy shine and smooth rounded lines. although I don't believe it produces the power that it claims to produce,it does produce very clean and clear and sharp music reproduction. All in all I am quite pleased with the performance of the Crunch PZX1800.4. I will mention that if anyone is looking for real power from an car audio amp go with a class D amp and not an A/B class audio amp. If you are looking a more than decent amp with a low budget in mind,you can't go wrong with the Crunch PZX1800.4
Beautiful mid and high amp
Had the crunch 1000, sounded pretty good went to the pzx1800.4 and everything came to life .well worth the money.
Great for the price
I've been using this for 4 full range speakers. Has them sounding very clear and loud.
Verified purchase
good design
i brought one of these, look good and strong, but im yet to install in my car.
