I was going to go with something different, possibly cheaper brand. Well, thanks to my wife I decided to spend a little bit more, (difference was like 40$, x-mas sale) I decided to stick with Down 4 sound products. I own 2 already this will be the third. What can be said, absolutely best bang for your buck. You can't find features on other amplifiers in this price bracket. Plexiglass bottom!!??? They aren't afraid to showcase the build quality. Shipping was earlier than expected, even through the holidays and crappy weather. All i can say is that I'm completely satisfied with my purchases. For all things considered you can't go wrong. 5 A Good Budget Amplifier | D4S JP84 4Ohm 400w RMS 4 Channel Class D Posted by Vince on Dec 06, 2025 I just had to purchase a second JP84 amp to complete my personal build. Running both amps @ 4Ohm bridged to (2) D4S Hexicone NEO HexiPRO 65, and (2) Pioneer 4" B401Pro tweeters. This system pushes my mids and highs to 50% of their RMS capacity. Along with (2) DDaudio 10" Redline subs powered by their 1100.1D 1100w RMS monoblock amp. It produces very clear audio to a filthy dBi... I do enjoy driving my truck now! 5 D4S JP84 Supplies the Power I Lust Over Posted by Vince Chris on Aug 11, 2024 I just love this little budget D4S amplifier. I paired with (2) D4S 65 v2 6.5" midrange speakers, (2) Pioneer TS-B401Pro 4" tweeters and built a chuchero box. It's loud AF with a FILTHY frequency range and NASTY clarity! View All Close
