Rockford Fosgate PBR300X4 Punch BRT 300 Watt Ultra Compact 4 Channel Amplifier Reviews
The PBR300X4 is a full-range 4-channel amplifier designed for stereo front/rear systems that requires little space. Rockford's Boosted Rail Technology provides an ultra efficient-design generating 300 Watts of power, and the amplifier also boasts a variable hi-level DC offset turn-on circuit for easy installation into any OEM system. Great for motorcycles and recreational vehicles.
 | Rockford Fosgate Punch Series AmplificationFor over 25 years, Punch amplifiers have set the standard in the car audio amplifier industry and they continue to do so today. It's the reason that they have become the most popular amplifiers in the world. Each of the Punch family amplifiers reproduce sonic perfection along with impressive power in a compact chassis. |
Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
DSM--An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces. The discrete components are laser etched to meet a particular value and a very low tolerance. This lower tolerance improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. These superior components are used by aerospace, automotive, and cellular manufacturers.
Heat is often inefficiently dissipated across a heatsink causing "hot spots". This impacts important design goals, which are:
Rockford Fosgate engineers have developed an award winning cooling design called DTM. This patent pending design seamlessly manages the output of power supply temperatures, while evenly distributing the excess heat across the entire amplifier.
MEHSA3 (Maximum Efficiency Heat Sink Application--gen. 3) is a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques, using the exact same components. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward & outward to quickly dissipate heat from each device across the heatsink. This process combined with our optimized heatsink designs, DSM (Discrete Surface Mount) technology and MOSFET devices, allows Rockford Fosgate to squeeze more watts per cubic inch from every output device as well as provide consistent thermal stability. The 3rd generation creates a dielectric layer between the ceramic topside and the aluminum base that retains all of the electrical isolation and capacitive coupling of the original MEHSA material increasing it's thermal conductivity. The higher power handling results in a 20% reduction in thermal impedance.
NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
In the early 70's, Jim Fosgate studied the acoustical properties of automobiles. Utilizing a real-time analyzer and pink noise, he would graph out the acoustical characteristics of each car he tested. Jim discovered three problems that were common to all cars:
The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.
Setting the standard for excellence in the audio industry, the Rockford Corporation markets and distributes high-performance audio systems for the mobile audio aftermarket and OEM market. Headquartered in Tempe, Ariz., Rockford Corporation is a publicly traded company and manufactures its products under four brands: Rockford Fosgate, Rockford Acoustic Design, Lightning Audio and InstallEdge.com.

Kicker 08ZX2002 2X100-Watt Stereo Amplifier Reviews
 Trouble-free amplification and loud, clear sound. Click to enlarge. |
 All ZX Amps are now outfitted with differential RCA inputs. Click to enlarge. |
 Upgrade to ZX850.2, ZX550.2, ZX450.2 or ZX350.2 for an included remote bass control. |
ZX-Series Amplifiers return for 2008 as reliable as ever--21 no-fault options to run a complete car audio system. Two-channel, four-channel, three- and five-channel hybrids, and absurd single-channel subwoofer amps round out a hard-working, noise-free lineup known for supplying the force until the listener shuts the music down. And now all ZX Amps are outfitted with differential RCA inputs, completely eliminating unwanted whines and audio trash and making for the most enjoyable listening experience possible. Differential inputs and new automatic turn-on modes make ZX Amps some of the most complete power producers on the market.
ZX Stereo Amplifiers
Eight ZX.2 Stereo Amplifiers, from a space-saving, 50-watt model up to a 425-watt thumpin' one, offer a bundle of features that designate them unbeatable. Each amp includes a built-in 12dB/octave high-, low-, or all-pass electronic crossover variable from 50 to 200 hertz, and a KICKEQ Boost that offers up to 18 decibels of bass centered at 40 hertz.
For added convenience, balanced differential inputs make KICKER ZX Amplifiers compatible with any factory radios, and they eliminate unwanted noise in a system. Boost, gain, and crossover frequencies are top-mounted for easy access, and a handy protection indicator featuring a new flashing yellow low-voltage light enhances the end panel. "Soft-start" circuitry lessens initial shock load when powering up, and a muting circuit cancels audio noise that surges down the line. One of three different automatic turn-on modes (remote, DC offset, signal sense) can be selected on the end panel to best suit the system setup. A mountable remote bass control directing sub output comes standard with the larger four stereo amps.
