Bridgeable
Delivers two channels or bridge mono for subwoofers. The PB171X cranks out 2 x 50 watts RMS at 4 ohms and is 2-ohm stereo stable for 75 watts x 2.

Selectable Crossover Modes
The built-in crossover can be set to full for normal full-range systems, or low-pass/high-pass for delivering specific frequencies to components or subwoofers. Low-pass and high-pass frequency controls are provided for setting the crossover frequencies.

Input Versatility
The PB717X includes both high-level and low-level inputs, so you're covered with the various types of car stereos. The high-level inputs take direct speaker wire leads, while the low-level use RCA plugs.

To further match the amplifier to your receiver/head unit, a variable input level control is provided to dial in the perfect setting without distortion.

Bass Boost
Subwoofer fans rejoice: The PB717X features a bass boost of up to 18 dB, for added rumble.

MOSFET Power
The MOSFET pulse width modulated power supply helps provide excellent sound quality, minimal distortion, and efficient power handling.

Comprehensive Protection
High-performance audio requires a lot of power, and things can get hot quickly. Like any solid car amplifier, the PB717X features protective circuits. Overload and thermal indicators let you know they've activated and shut off the amp. In the event of a short circuit, power protection is provided in the form of easily replaceable fuses.

It does everything it's supposed to. I hooked up two 12" kickers to the existing stock system in my Jeep and they pound. They're so loud I had to turn the base all the way down. It's a good cheap buy for a 2 channel set up, it rocks.....5 Stars...

Wow, what can i say about this product. A lot of my friends were like, "dude this thing would last a month", well i am happy to say it has and more. My subs sound really good with this amp, I really didn't expect this thing to do a whole lot, but it hits hard. Buy this and I promise you wont regret it.

When i got the package i was shocked by the size of this thing. it was HUGE and HEAVY. It's not an issue for me since all i look for is performance.As for the performance, i think it's pretty good. I don't have a decent subwoofer yet ( will buy 1 soon), but i hooked up a supposed 300 watt roadmaster speaker to this amp to see if i hooked up everything right. it was pounding like crazy and speaker got blown the *** up in 5 minutes. i was happy to see that because when i read a review saying that it was way under power of what it claimed to be, i was a little bit skeptical. Nevertheless, it's a 40 dollars amp. Cheapest in its price range. Even if it's only 500 rms i still think it's a heck of a deal. The amp has a lot of tweaks that i have yet to explore. I'm not Native English speaker so i hope you understand and find this review helpful :). Peace!

EDIT: it's currently pushing 1 12'' kicker cvx!!!!!! it bangs! you have to adjust the amp to get the max power out of it! i'm double happy with this amp right now! no overheatings or random shut downs! awesome awesome awesome!!!
