Great little amp

i wasn't happy with the sound of my cheap door speakers running off the head unit so i snagged this cheap little amp and am beyond impressed with its performance. The increased clarity and pop provided surpassed my expectations from the first time i turned it on.

pretty good amp

naturally I didn't expect much from an inexpensive amp, and I am perfectly content with the performance of this little guy. The output is very respectable and the amplifier seems to run effeciently, it also doesn't get hot. My installer set the settings for me, but I think I'm going to retune everything after I get a subwoofer in. Thanks for the fast shipping Sonic!

Reasonable price. Top quality!

I purchased the amp along with another to do some testing. The quality is very good. After the project I installed both amplifiers in a classic hot rod. Still working very well

Very Nice For The Price!

I purchased the Crunch PDX-1000.4 for the purposes of controlling the high on my custom audio system in my E320 Mercedes. The Crunch PDX 1000.4 is serving its purpose to perfection. However, I do recommend you use an audio cooling fan to keep it from overheating. Other than this; it's a great product. Thanks Sonic!

Great Amp for The Money

$60 for a 4 channel amp? Granted I know it will never do 1000w max but that's not the reason for the purpose?. Sending about 75 to 90w RMS x4 to 6.5 Comp. by Renegade. Sounds great. Too many people buy Tier 1 speakers/subs and push them with Tier 3 amps....... Fail 99% of the time. Great product for the money

Not a bad budget amp

I bought this amp for a budget build in my buddies '07 Honda Civic. We are using it to drive 4 PPI 6.5 inch speakers. They play loud enough to keep up with the subs. I do wish the Crunch logo lit up when it was on but I knew it didn't when I bought it. I haven't tried bridging to drive a sub, but as a cheap front stage amp it does the trick.

Great Value

It works if used correctly. I'm running some pro audio 8s and it's clean and loud. Most car audio works if used correctly and tuned properly. I will prolly buy another one to run another pair of 8s really soon.

not bad for the price

i purchased 2 of these amps, 1 for my ford f150 and 1 for a Mitsubishi lancer.

the stock head unit was used in both vehicles and that is why I chose these with the high level inputs.

that was a big mistake, if you are using the a stock unit do your self a favor and buy a line converter so you can use the rca jacks, it will save you a lot of hassle.

we had them professionally installed, the lancer had several issues and when all is said and done there is still a hum, it is really quite annoying.

the ford install was fairly straight forward, but again a hum.

the installer believes this will disappear when we get a line converter.

the sound is decent, in the ford I have fosgate 6x8's and in the lancer fosgate 6"
