Customer Ratings & Reviews

good performance

this amplifier was installed in a 1996 intreped.my customer also needed to have his rear 6x9 speakers replaced.he chose rockford fosgate.{good choice}.the amplifier is powering all 6 speakers and it sounds great.

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!

god for the price

This amp has enough power for me. Sound is great and plenty of bass. I would recommend this amp to my friends.

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"

Inexpensive amp .

Cheap price , however sounds cheap too . I put it in a work truck so it will suffice , but not a high quality sound . Good unit for the normal vehicle needing a bit more power .

PDX1000.4 CRUNCH AMP

THE PDX1000.4 CRUNCH AMP IS A VERY GOOD AMP. I'M HAVING A PROBLEM WITH OVER HEATING. I PURCHASED SOME FANS TO SOLVE PROBLEM.

Good Amp

Good bang for the $. Easy to install. Would buy again.

Just OK.

The reason why I have negative feedback is because I took my items fresh out the box to my local audio shop that I have used over and over again, to have my new order of Crunch amp and Hifonics subs installed and the first thing they asked me was "where did I get this?" I then explained and they told me that he could not believe a company like this would send a product out fitted with fuses that weren't right.. It came with "Kangaroo gas station fuses" when it should have come with another type of fuse." This company has been in business over 16 years, and very respected. I was let down and felt cheated. Because i spent a ton of time researching the right product and then that happens it questions me returning and promoting and providing referrals.

Its a shame because I really enjoy the performance of the products.

Clean and powerfull.

I like this amp alot. I got it to power four 6.5" door speakers and it sounds amazing. I would buy from Sonic in the future and I would also buy a crunch amp if you want good quality at a reasonable price.

Great with one exception

My system was put in professionally, and decided for a new amp. It sounds great, the quality is great, but it continues to over heat and I have to shut the system off for almost an hour to allow it to cool. I had the wiring rechecked just to be sure and everything was good so I can't figure out why it's over heating
