    Absolutely love this amp. Upgraded to this from three jp234. The clip in feature should be a new standard. It's pushing 8 uscmr 8's with ease of course. Super happy with it.

    Awesome amp, extremely powerful.

    This is an extremely powerful amplifier and not to be seen as just average. Must have electrical power for it because its hungry for power and must have powerful speakers. I'm love all the JP Series amplifier. Purchase any one and I promise you'll be more than satisfied.

    As good as it gets

    I'm currently running the 234, 454 and 10.4. Boy let me tell you. These things got ALL the jewce! And they sound great. I'm currently running mine at 6 ohms and still getting incredible power. They're excellent build quality. The best tiffany RCA'S you'll find. But most of all, I like the bandpass crossovers. They allow you to cut both the top and bottom end. And they aren't cheaply made or super sensitive so they're easy to dial in exactly as you want them. When I tell you that I've tried them all, that's a factual statement. And these are my favorite 4 channels to date. The JP amps are some of the best you'll find and the price is fair. What more do you want?
