1. BOSS Audio Systems R1100M Monoblock Car Amplifier - 1100 Watts Max Power, 2/4

• Low level inputs: line level inputs, also known as rca inputs or low-level inputs, use rca interconnect cables to link the r1100m with the source unit. most aftermarket radios have multiple pairs of rca outputs that can connect to multiple amplifiers
• High level inputs: speaker level inputs are commonly referred to as high-level inputs. speaker level inputs will be used to connect the r1100m to your factory radio or an aftermarket radio that does not have low-level (rca) inputs
• Dimensions: the r1100m is 9.1 inches in depth, 10.4 inches in width and 2.3 inches in height. it can be installed in a variety of different places due to its slim and compact design
• Low-pass crossover: a low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. you will use the low-pass filter to primarily keep high notes out of your subwoofer(s)
• Power: maximum power output of 1100 watts at 2 ohms into one channel. max power output of 550 watts at 4 ohms into one channel. this amplifier is designed to run your subwoofer(s) giving them the power that they need to perform as they were meant to
• Variable bass boost: variable bass boost allows you to adjust the low bass within the boost range to just the way you like it

2. Planet Audio AC1500.1M Monoblock Car Amplifier - 1500 Watts Max Power, 2/4 Ohm

4. Lanzar Amplifier Car Audio, Amplifier Monoblock, 1 Channel, 3,000 Watt, 2 Ohm, MOSFET

• Audio evolution: this amplifier car audio features excellent frequency response rates and crossover network that place these amps in a class of their own
• Great deal: often a monoblock amp comes with a high price tag yet the lanzar mono amplifier is budget friendly with all the features, reducing crosstalk between channels
• Sound specialization: this high-powered power amplifier is cutting edge technology at its finest nickel-plated rca connectors and speaker screw-down terminals ensure a secure connection between amplifier and speakers that allow distortion-free sound
• Rca jacks: the line-out jacks allow you to build multiple amplifier systems without having to use splitter cords to distribute the signal this makes it easier to bring one set into the first amp, then use the line out jack as the feed to the next amp
• Intelligent design: the amplifier monoblock features include power and protection led indicators, soft turn-on/off, and 1 channel amp design

5. Planet Audio PL3000.1D Class D Car Amplifier - 3000 Watts, 1 Ohm Stable

• Power - 3000 watts max x 1 @1-ohm, 1500 watts max x 1 @2-ohms
• 1 ohm stable - able to continuously power loads of 1 ohm without encountering difficulties such as overheating. typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to
• Strapping capable - you are able to strap two pl3000.1d amplifiers and double the power that is being sent to your subwoofer(s). you now have the ability to connect more subwoofers to take advantage of the extra power
• Specs - dimensions: 11.9 x 7 x 2.3, weight 6.7 lbs.
• Variable low-pass crossover - subwoofers reproduce sound based on a number of different low-range frequencies. you can set exact sound specifications for the bass frequency reproduction
