Bought this along with the JL Audio 12w7ae and had a custom enclosure built. This was installed in a 2012 Scion tC. Very clean sound and it hits super hard! Best setup I've ever owned. Sonic Electronics was super fast getting the sub and amp to me and at a much better price than anyone else! Highly recommend this setup. Even if you don't get JL, I would still recommend buying from Sonic!

JL Audio's Flagship Series of amplifiers offer unmatched performance from an ultra-compact chassis. These Class D amplifiers require less power, generate minimal heat and take up far less space than the common amplifier design. HD Series amplifiers reproduce your music with outstanding accuracy, providing high-fidelity sound even under the most demanding conditions, thanks to a number of JL Audio exclusive technologies. Single Cycle Control (U.S. Patent #6,084,450), R.I.P.S System and Advanced Rollback Protection are just a few of the technologies that sets the HD Series apart from the rest of the market, all designed to deliver top-flight audio performance. In addition, behind every HD's removable security cover, you will find studio-grade signal processing with fully variable crossover filters to properly tune in your setup and put all the technology under the hood to good use.
Also included are JL Audio's noise-killing, highly flexible differential-balanced inputs with remote level control capabilities via the HD-RLC remote level control (sold separately).
Advanced Rollback Protection
JL Audio's signature Advanced Thermal Rollback protection system eliminates annoying thermal shutdown events to keep the music playing, even under the most demanding conditions. Should the amplifier reach an unsafe operating temperature, a special circuit rolls back peak power output, without changing gain, until the amplifier cools down to a safe operating temperature. The red "Thermal" LED will light to indicate this condition has been reached. Once the amplifier cools down, the circuit restores full peak power output and the red "Thermal" indicator reverts to its normal state. The operation of Advanced Rollback Protection is inaudible in most cases.
R.I.P.S. System
The HD750/1 employs JL Audio's exclusive Regulated, Intelligent Power Supply (R.I.P.S.) design. This sophisticated power supply allows the amplifier to produce its optimum power (750watts x 1) over a wide range of speaker impedances. Unlike conventional amplifiers that require a specific impedance to produce optimum power, the R.I.P.S.-equipped HD750/1 gives you the freedom to use a variety of subwoofer configurations without sacrificing power output or sound quality. The operation of the R.I.P.S. circuitry is entirely automatic and adjusts itself every time the amplifier is turned on according to the lowest impedance present at the speaker load.

Notes from JL Audio:
- *If you connect a load higher than 4Ω nominal, power will drop by half with every doubling of impedance above 4Ω stereo. If you connect a load lower than 1.5Ω nominal, the amplifier protection circuitry activates a "safe" mode which reduces amplifier power to protect the circuitry from failure (the LED status indicator on the control panel will light up amber to indicate that this has happened). See page 14 for details.
- **We do not recommend the use of "copperclad aluminum wire" or "CCA" wire because this wire is significantly less conductive than pure copper wire. Only use pure copper power wire, such as JL Audio's Premium Power Wire. Tinned copper wire (silver color) is acceptable as the tin-plating is only a very minor component of the wire.
- **The HD750/1's "+12 VDC" and "Ground" connections are designed to accept 4 AWG power wire. 2 AWG or 1/0 AWG pure copper wire is recommended for any power wire run longer than 72 inches (180 cm). This larger wire should be reduced to 4 AWG using a distribution block within 36 wire inches (90 cm) of the amplifier's "+12 VDC" connector. For runs shorter than 72 inches, 4 AWG pure copper power wire is acceptable
Power Specifications - Subwoofer Channel
RMS Power @ 4 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.

Amplifier Specifications
Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
HD (JL Audio)
Amplifier Class
An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.
Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.
Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.
Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.D
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
1 - Mono
Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.
It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.
The RMS power rating is more accurate, and we recommend using it for product comparison.
750 watts
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.
RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.
The RMS output figure is much more accurate than the peak rating when comparing products.
750 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
4 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
1.5 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Not Bridgeable
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
1%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
1 pair
Built-in Crossover
A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.
When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below the set point gently or harshly roll-off, depending on the steepness of the slope.
The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.
50 - 500 Hz
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.
The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.
50 - 500 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
30 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
111 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Optional (Accessory required and sold separately)
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
60A X 1 In-Line Fuse Recommended
Total Fuse Rating
The total amperage an amp requires.
Strappable
Some amplifiers can be "strapped" together in order to increase the output of a single audio channel. These amplifiers feature RCA preamp outputs, allowing you to pass the signal directly from one amp to the other to ensure consistency.
No
Sonic Certified Amplifier
Sonic Certified amplifiers have been tested by the experts at Sonic Electronix to meet or exceed the wattage ratings provided by the manufacturer.
If this is marked as Yes, then you can trust the wattage ratings.
If marked as No, then we have tested the amplifier and it did not meet the advertised wattage ratings.
If marked as Not Tested, then the Sonic Electronix experts have not yet been able to test the amp.

JL HD750/1 mono amp
July 2, 2009
I have this amp connected to a JL 12w7 prowedge sealed box. it hits pretty good. I wish I would have saved a couple hundred more and baught the 1000/1v2. bottom line is this: if you have limited space and want a great amp then this is the way to go. If you have the room and want one of the best amps made, then buy the JL 1000/1v2 amp. it's an old school analog amp built to give real power. The HD series are digital and dont seem to have the umpff like the 1000/1v2 slash series. It matters what kind of sub you have too. I'm upgrading to a ported 12w7 HO box and the 1000/1v2 amp just cause i know it will sound better. Overall i'm happy, but you know how it is.

Looking for marine grade Amplifiers rated at 675 hz crossover frequency?
Best Answer: Hi Mike,
Very few monoblocks - if any - will have a Low Pass Filter that goes that high. In fact, those that allow a full-range signal, like the HD7501, will still cut off their LPF option anywhere between 120 - 500 Hz . This is because the frequencies above that are considered Mid-Range frequencies, frequencies that will harm most subwoofers.
