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.

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.

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...

I am powering two Rockford P-2s 12s and have it dropped down to the right ohms but this just doesnt seem to put that much power out. It is a inexpensive amp and I would expect big boom but would have liked to have a bit more. This product was shipped extremely fast and was packaged perfectly. I would reccommend this product for the price.
