Down4Sound JP34 AB PURPLE | 590W RMS - 4 Channel Amplifier

All the JP amps I have bought have exceeded my expectations

Got mines installed this afternoon and after getting the gains set on it, I went out on a two hour long drive. Beating the hell out of this thing and it brought out sound clarity in my mids and highs that I've been lacking for a while now. So much so that now I'm going to go out and upgrade my mids/highs to better match up with this amp. Its beautiful and sleek. The only complaint I have on it currently is that even with a 4ohm load this amp goes get quite warm. Even though the fan is doing a good job displacing all the heat this amp generates, it might be wise to add some additional cooling fans if you have to mount it up under a seat , like I did in my 2007 Chevy Suburban.

Love this Amp. The purple is beautiful and this can take a beating. Have it run on 4 ds18 Speakers and tweeters on ch 1 And 2 with 3/4 bridged to a sub. Love the sound!!! Replace a powerbass amp. Quieter, loud, and doesnt overheat. Love it

amazing amp. the color is great and the specs are nothing short of amazing. i watched big d do an amp dyno vid {after i had got mine} i was blown away at how great it did. more then rated. this is a real sq amp. run some good speakers and give your ear holes some pleasure

Im used to American bass amps but i tell you pound for pound my stuff is clearer louder and easier to tune, sorry American bass jp amps is who im sticking with now

I have the little blue one and it’s very nice. Then I saw this Beautiful beast. I have it on 2 MB Quorts component sets and it insane!! The tweeters have a tick that makes you blink every time. Lol. String instruments and vocals are perfect. Finely not being drowned out by the subs. Lol. Keep up the good work. Everyone I show it to, wants one.

This amp sounds as good as it looks at the moment I’m running 2 sets of sundown e series components and they came alive big difference from my skar 75.4 ab and it was shipped to me in 2 days all the way to Mobile Alabama jp keep it up

I have this amp pushing the sundown components and coaxles sounds great. Can’t wait to get my jp23 back

JP, you've outdone yourself once again. When I saw this go up for pre-sale and that it was class AB, I bought it, even though my project won't be for a long while. Throwback to the 90s of a PPI surfboard 4100, but better in every way. I have no doubt it will blow past it's rating and sound amazing. Waiting for big-D's review and dyno. Best amp quality and value in the entire car audio industry, hands down.

I love this amplifier!! Plain and simple. I bought one last week with a link from Big D (Williston Audio Labs). It showed up in only three days and I was able to install it in my S10 before Slamology. In my setup Two channels run my four highs and the other two channels are bridged to run my sub. This amp is absolutely gorgeous in your hands but it also makes sweet music. I’m an old school car audio guy. I’ve been playing with car audio for 30 years and worked in car audio for a decade. I haven’t bought a new product in a very long time and when I saw this heat sink I knew this would be my first D4S purchase. It exceeded my expectations. The stereo separation is sharp & honest and the sound quality is very high. My sub digs deep and has strength. Highs are sparkling and clean. The frequency range of this amplifier paired with the versatile crossover makes it nice and flexible for many applications. I listened to it all weekend at Slamology and easily have 12 hours listening time and let me tell you, it sounds FANTASTIC. I visited the D4S tent on Sunday and bought another one because I know these will be in high demand and I am putting one in my daily driver too. JP and the crew are super nice and bend over backwards to make you feel welcome. Great group of folks to buy car audio from because you will get more than what you paid for plus I appreciate their presence at Slamology. This amp has earned my respect and so has DOWN4SOUND. Thanks from all of us old school lovers for this US Amps homage with modern awesome Guts. It’s performance lives up to its looks and has impressed everyone I’ve shown and let hear it. I plan to talk about it with every car audio fan I know. Sincerely, your new customer.
