The JBL MS-A5001








JBL MS-A5001

Sophisticated crossover functions

Each of the MS-A5001's outputs can be low-pass, high-pass or band-pass (low and high) filtered. You can choose among 97 different crossover points between 20Hz and 20kHz, and select crossover slope rates of 6dB, 12dB and 24dB per octave. For further flexibility, crossover settings are completely independent for each output.

DSP technology

The MS-A5001 uses digital signal processing (DSP) for all input-mixer, crossover and output-level controls. Compared with analog crossover circuitry, DSP circuits produce extremely precise results with a minimum of audible artifacts.





Connects to any analog signal

The MS-A5001 features RCA-to-bare-wire adapters to connect to all line-level and speaker-level inputs, and includes a selector switch for matching the amp's input to the type of signal that it receives.

JBL MS-A5001

Digital input mixer

The MS-A5001's digital input mixer simplifies configuration by allowing any input signal to be routed to either speaker output.

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.

RMS Power @ 2 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 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.
MSA (JBL)
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 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.

500 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.
2 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.

Low-Pass (LP)
High-Pass (HP)
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.

20 - 140 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.

20 - 140 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.
80 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.
40A x 2 
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
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Yes
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.
Yes
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

When I saw this amp and read up on it I had to have it. It's a lot of bang for the buck. Setup is scary simple. The digital circuitry and class D design is clean and second to none. I have this paired with a JBL P1224 in a ported box and it is much louder than I expected. Very nice.

I am using this for a pair of Pioneer TS-W260S4 subwoofers and a Kenwood Excelon 998 in a 2003 F-150.

This was a huge improvement over the OEM installation, and I am really enjoying the punch that these deliver!

The installation and setup of the amplifier went well enough without any major issues.

great little amp

February 17, 2015

The shipping was fast and packaged appropriately. The only minor inssue I ran into during installation was the remote input. The input had a 1.5 hex instead of 2.5, so the supplied Allen wrench wouldn't fit. I would suggest reading the book a couple of times b4 setup. I have it pushing a Fi Audio X10 in a 1.3 ported enclosure tuned at 33hz. It sounds better than when I had the kicker zx750.1 pushing it. I'll have to update this review once I have it for awhile to give opinion on durability.

December 27, 2014

Purchased this amp for the features. Upon arrival, it did not work. I hooked up my Kicker and completely forgot about it. Sonic has a great warranty, so I sent it back- even after the warranty had expired. They gave me another even, so I hooked it up and mounted it on the box, as my box has an amp rack. I blew the screen. It still works great but I can't change anything on the amp as I cant see what I am doing without the digital display. Shame on me for that one!

I LOVE IT!!

March 29, 2015

I purchased this amplifier to power two RF P3 10inch, dual 2 ohm subs. It does an excellent job at this but I love it soooo much, I'm getting one more and upgrading to two 12inch T1 dual 4 ohm subs. This amp is extremely easy to set up considering the amount technology packed into it. There are almost all usable crossover frequencies available, lo pass and hi pass. Good job Harmon Kardon on an excellent product!!! I've used it for two weeks now so my 5 star durability is a bit subjective...

April 5, 2015

Separate input/ouput level adjustments, digital crossover (no guessing!), subsonic filter with variable frequency & slope, defeatable crossover (on hpf & lpf), variable slope on lpf (same as hpf), automatic turn-on, underrated power, wireless bass remote... What's not to like?? Perhaps the only things I could find is not being 1 ohm stable for those that need it & some had issues with the wireless bass remote staying connected, but other than that this is probably the most versatile mono amp on the market and especially at this discounted price level. These will be missed when they're completely gone from the market.

truly amazing

June 11, 2015

I've owned many amps by orion hcca jl audio memphis audio kicker and even a JBL gt series back in the 90's. First I am impressed with how compact this amp is. The digital read out and being able to perfectly dial the hz in and signal is something I've never seen before and truly comes threw when dialing in your preferred sound. I have it hooked up at 4ohms to 2 12 gto single 4ohm subs in vented box. I can not believe the sound 250w per sub this amp produces. Just incredible. This is by far one of the amps I've ever owned. Top notch two thumbs up I can't imagine it getting any louder and only have it hooked up with a factory radio. But when I get a aftermarket head unit and run it at 2 ohm it will probably be the best overall system I ever owned JBl out did themselves here. For a amp this impressive under 200 you'll be a fool to even look at anything else. Hats off Harmon. Thanks sonic electronix for such a great deal.

I put this amplifier in my Camaro Powering two twelve inch subs. It has more than enough power to fill the car, but don't expect to be able to hear your music two blocks away. It is easy to set up and has a very useful suite of features. Overall excellent quality and good price. It doesn't look flashy, but I don't need it to. Would definitely recommend for use with JBL's 1400 watt subs

What a deal!!

July 21, 2015

I was considering purchasing this amp for the full $399.99 retail price several months ago. I waited and SonicElectronix had it for (cheaper) so I jumped on it immediately and I'm glad I did. This is a compact amp that will fit just about anywhere you would want to install it. It features some great tuning features and a lot of power. If anything the power is underrated on this unit rather than overstated like so many amps on the market today. The high-level input adapters are appreciated since I installed it off the rear speakers. The remote turn-on feature is nice because I don't have a dedicated remote turn-on line from my factory radio.

I did have an issue with a loose connection internally in the amp. I sent it back to SonicElectronix and am awaiting the replacement.

I got some pretty awesome bass and a ton more power than I was expecting. Have had 0 issues, and have maxxed this thing out for 2-3 hour drives. It never stutters, it always hits hard, and remains clear. Definitely glad I went with this. If you're considering a 500 watt amp, this is it for the money.

Awesome amp, HUGE BANG for the buck !!

July 17, 2015

This was the first JBL amp I have ever bought. After a few months of "thinking" about it and reading several reviews, I decided to take the plunge. I am NOT in ANY way disappointed. Both the power of the amp, and sound quality (if you tune it the way they recommend) are both impressive. Installation was easy, tuning was easy to do, although I felt the step by step instructions were mildly vague in a couple of areas, taken a moment to look things over they were easy enough to figure out. I do intend to buy at least one more of these and a 5 channel JBL amp for my Suburban. (once I convince my wife that is...lol) I would ABSOLUTELY recommend this amp...no doubts at all. Also, Sonic, as always, shipped fast and free....Thanks guys!

UNIQUE FLASHY AND NICE BUT..........

July 20, 2015

its nice to have endless options, real world power over manufacturer, nice looks, small, stays cold, but ive had a few and emailed harmon they are know for memory issues digital setting don't always stay. also the soft start on it doesn't work well. still has a pop other amps don't in my car. also in high level it takes an eternity to turn on after radios on. sound is decent thanks to options. basically i think there are better amps if you can deal without the nice flashy looks. my kicker cx600.1 sounds 1000 time better turns on instantly has no pops and put out same power.

A lot of power in a small package!!!

August 14, 2015

First off it should be noted that I am a HUGE car stereo fanatic and usually only deal with HIGH end and competition level equipment like JL Audio, Rockford Fosgate, Creacendo Audio, DC Audio, Sundown Audio etc. etc and so naturally I was skeptical about this amp at first but when I saw the price drop on Sonic and based on other reviews along with Sonics own dyno test of the amp Im glad I purchased it. Its very small but packs a huge punch. I currently have it installed in a 2014 Infiniti Q50 Hybrid with 2 12" JL Audio 12TW1 Subwoofers in a sealed JL enclosure @ 2ohms and this little amp really hits hard. I am really impressed with the features of the amp and being able to change the curves on the fly is a plus. The fact that the amp has both high and low level inputs means I dont need to put a high-to-low, just run the feed from the factory sub right into the JBL and its done. The calibration CD it comes with makes level matching a sinch. The only negative this product gets is the fact that it DOESNT come with the wireless bass knob... And you can forget about finding it online too.... I searched for 2 weeks and finally found it on Amazon UK but at a hefty price tag (80$). It was worth it though as this remote is wireless which means NO WIRES TO RUN. It paired easily with the amp and really makes a difference as it doesnt asjust the gain like alot of other remotes but actually changes the sub curve... Did I meantion its wireless?? I would definately recommend this amp to anyone looking for some big bass in a small package without the big price tag. JBL is a name you can trust. By the way the amo is rated at 500 watts but youre easily getting over 900 watts @ 2ohms. Im happy and i plan on getting the 4 channel when I get the chance.

I'm using this little amp in a Jeep Wrangler jk 4 door. It fits nicely under the passenger seat for a clean look. I'm using it to push a single 12w6v2 in a slot ported box. It matches well with the sub. It has just enough power to push it to its limit. I'm really happy with this purchase. Great price, and fast shipping.

Easy to Use Crossover Points but thats all.

May 6, 2016

I've owned this amp for two years, I recently upgraded to a hifonics brx 1600.1D.

Pros: Easy to set the Gain
Digital Crossover Points
Compact Size

Cons: hi-level inputs known to fail
Wireless bass knobs never paired correctly

Failed after two years, with an error code of 04! JBL and Sonic Support have no idea what this code means and with no resolve I moved to a Hifonics BRX 1600.1D -- Problem Solved

Twice as nice.

April 3, 2016

I recently purchased 2 of the JBL MS-A5001 digitally processed amps. I am running one each on JBL GR5-15" subs in two sealed single enclosures. The bass is so deep warm rich tight and clean from the processing in these amps. Still pushing everything with a stock head unit in a 2000 TOY Camry. Plenty of output room left on the Amps. Run them for hours and they are hardly warm let alone get hot. Sonic once again provides quality products with the best prices.

Wow! About all I can say about my recent experiences with Sonic Electronix and JBL. I am running 2 JBL GT5-15's 2 MS A5001 JBL monoblock amps, one on each sub. Signal coming off of the stock head unit in a 2000 Toy Camry. The amps are barely idling and the subs are still tight as the day I bought them. Taking it easy on them until they break in, but judging by the quality of the speaker and it taking some time to break in, I can tell this system is going to last. The bass response of the subs is tight and powerful the amps are clean and efficient. Once again Sonic and JBL exceed expected standards in quality product product cost and always great customer service. Thank you Sonic JBL

I searched for months for the perfect amp. I was looking for sound quality and value. This amp is a ridiculous value. Forget about alpine. They're great amps but they don't touch the value here. This thing is super sophisticated and it's rated at 500 watts but it puts out closer to 850 clean watts. I don't have a super duty charging system so I needed something efficient and this is definitely efficient. JBL far exceeded my expectations. Especially for the price. By the way it's CEA rated.

Great JBL MS-5001 Amp & Great Service from Sonic Electronix

November 5, 2015

first I want to point out that Sonic Electronic made unfortunate problem I had worth having because of there customer service! A few months back I bought a JBL MS-5001 amp and the very first time I turned it on after the install the amp made some RCA input noises? so I called Sonic for a RA (return authorization) number and boxed up the Amp and had it ready to ship, Well I went on a two week vacation and when I came home and seen the box still where i left it I realized that I forgot to take the Amp to UPS before I left, I was worried that it would now have to be repaired and not just replaced since now it is past the 30 day return policy, I felt that Sonic went out of there way to help me by going a head and sending me a brand new one anyway..... The JBL MS-5001 is even better than I had hoped it would be running a single 4 ohm DVC 12" Sub at 2 ohms and does not even get warm after pounding that 12 all day.... very happy ...

Best Answer: Hello,

Your answer is in the specs. =]

Two Rockford Fosgate P3D2/D4-12 will be asking for 1200w RMS. The MS-A5001 is only able to produce ~500~750w RMS @ 2ohms. So, although the MS-A5001 is a Fantastic amplifier, it is only able to put out enough power to drive One sub at its full potential. The best match for two drivers will be the Rockford Fosgate R1200 or NVX JAD120.1; of which, will need the Dual-4ohm version wired down to a 1ohm load. If you wish to go with the JBL amp, you will need Two amps and the Dual-4ohm drivers wired to 2ohms respectively.

Does this include remote control for bass and volume?
Mnnmat on Feb 11, 2015
Best Answer: Hi,

The MS-A5001 does NOT ship with a Remote. However, the JBL MS-WBC is the compatible remote for it. Unfortunately, we no longer carry, it is discontinued, and we aren't sure where you will be able to find one. However, we suggest taking the model number and doing a quick search. In the even you do not find one, we suggest going with a Universal Remote Level Control, which may very well be the best/practical option anyway. We us the NVX XBRC in our Install Bay when faced with such a scenario.

This amp does not turn off after the vehicle is off. All settings lost when the ignition is turned on. Please help.?
A shopper on May 4, 2015
Best Answer: Check your wiring. Use a multimeter to verify your positive reads 12v always, and that your remote only reads 12v when the car is on, or the key is turned to acc. If everything reads correct, then I would suspect that you may have a bad amp. However, it sounds like a wiring problem.

JBL MS-A5001

JBL GTO1014D

Best Answer: This amp will not work for those subs. Since they are dual voice coil, you need to find a sub that is 1ohm stable, and preferably bridge capable. Wiring the voice coils in parallel with each other in each sub brings each sub to 2ohms, then wiring the two subs in parallel it's the amp makes a stable 1ohm system. This is the best possible way to get these subs to hit hard and tight like a kick drum or an 808 bass drop. Don't put too much power into them though. I put 750watts through mine and they blew. Obviously. Keep it at 450-500watts at 1ohm. Hope this helped.

What's the best way to wire these subs? 4 ohm to 2 ohm or keep it at 4 ohm?
Logan H on Jun 25, 2015
Best Answer: It depends on the sub and the Amp you are using....If the Amp is stable at 2 ohms then you could wire it and see if it thumps...Otherwise, keep it at 4 ohms...
Read the manual on your Amp.....Always wire per manufacturer's recommendation!

Does this mean that it has a built-in line out converter?
Ryan D on Dec 22, 2014
Best Answer: Yes, There is a pair of RCA output from this amp and you could connect another mono amp from that output. So, for example, all you'll need is a pair of RCA from your head unit sub woofer output into one amp, then another RCA from that amp output RCA into the other amp input RCA. Hope that help and make sense.

I know it's not optimal, but if I use my vehicle's head unit speaker leads running to the stock rear speakers to feed this amp, would I totally disconnect leads from stock speaker, or just tap into them, leaving the stock speaker hooked up?
CohoCarl on Aug 19, 2015
Best Answer: Hi

If you are using the rear speaker wires from a stock deck, you are tapping into the rear sound and you will still get the left/right sound out of your stock rear speakers. If you want to just use the rear wires for a subwoofer then you have to disconnect rear speakers.

The other option is tapping in directly from the deck output wires and running a separate wire to the subwoofer. You would still have to connect rear subwoofer RCA's from pre-outs of the stock deck.

A shopper on May 8, 2015
Best Answer: Hello,

Compare to any SSL amplifier, literally Any, the JBL MS series is Very efficient. Coincidentally, it likely makes better power , being CEA Compliant, than that amplifier as well. Even if the latter isn't true, you will be able to keep your power for a longer period of time, which, in of itself, makes the MS a better option.

Audiopipe APMI-1500
Audiopipe APMI-1500
Best Answer: Hello,

The amplifiers are fairly power hungry, but not comically inefficient by any means. It really depends at what impedance you wish to run the setup at, but if we assume the lowest possible load, providing ~1400w, then you may require some upgrade in components. A proper battery will absolutely help, but you won't know until the amplifier is in the vehicle. A capacitor is not intended to help your vehicle, so if that is your main concern, don't bother with the cap.

Also, 4 Gauge is not intended for a "3,000 watt amp". Even very high strand OFC wiring in a VERY short length is only able to properly handle Half that. So please plan accordingly. Coincidentally, assuming OFC, 4 gauge is perfect for the APMI-1500.
