That’s because they’re running directly from the +12V supply.
There’s simply no way around it – most in-dash stereos are limited to about 15W-18W RMS of power for each speaker channel. The maximum volume you’ll be able to get from your speakers will be pretty low, too. They can’t drive speakers with the same clarity and low distortion as a good amplifier can. In-dash stereos are very limited in how much power they can produce. Whether you have a factory stereo or a great aftermarket (non-factory) one, adding an amplifier is one of the best decisions you can make. The benefits of using an amp to drive speakers
Additionally, most can be bridged to use 2 channels (or 3, depending on your needs) so you’re not restricted to using them with only 4 speakers. This saves installation space and makes it easier too. However, because they’re built together and not 2 separate 2-channel amps, they’re more compact. 2 channel vs 4 channel amp diagramĪ 4 channel car amp is basically an expanded version of a 2-channel amp. That’s helpful if you’d like to hook up 4 speakers and a sub to one amp. It means 2 channels are sharing the workload of one speaker between them and therefore and drive it with more power. This causes the speaker to receive a voltage audio waveform that is the difference between the two channels – resulting in more available power to speakers.Įssentially, bridged mode is a flexible way to get more power if you’re not driving 4 speakers. What is “bridging” an amp?īridged mode capability is a special design feature in which a “push-pull” set up is created: one channel (normally used for the left speaker) produces a signal that’s the opposite of the second channel (normally used for the right speaker). This drives speaker voice coils to move the speaker cone and produce sound.Ĥ channel amplifiers add more channels into a more compact and efficient design than separate amplifiers would have.Īdditionally, they offer more flexibility, as most can be configured for “bridged” operation which can give more power when you don’t need all 4 channels.

The XD700/5v2 also features the v2 Spec feature set, which consists of automatic turn-on capability (via signal sensing or DC-offset sensing), and a dual-range differential-balanced input section able to handle a wide range of input voltage levels. With the addition of an HD-RLC remote level control (sold separately), the amplifier's level can be directly controlled from the driver's seat. 1 & 2 high-pass filter allows its cutoff frequency to be adjusted from 50-500 Hz or 500-5000 Hz. This amplifier's filters can also be configured as a true 3-way crossover, with a low-pass filter for the subwoofer channel, a bandpass filter on Ch. All three filters offer continuously variable cutoff frequency selection from 50-500 Hz.

The XD700/5v2 includes a 12 dB / octave high-pass filter for one main channel pair, a 12 dB octave high-pass or bandpass filter for the other main channel pair, plus a variable slope low-pass filter for its subwoofer channel. The breakthrough that makes this much power possible in such a small chassis is our NexD™ switching design. With this incredible little amplifier, you can drive two pairs of quality component speaker systems with plenty of clean power (75 W x 4 4 Ω), while also delivering a stout 300 W of power to a subwoofer system. The XD700/5v2 is ideal for a complete audiophile-grade, subwoofer + four satellite system, and it fits comfortably in just about any vehicle. 5-Channel Class D System Amplifier, 75 W x 4 4 Ω + 300 W x 1 2 Ω - 14.4V
