Our take on the MTX THUNDER500.1

by Buck Pomerantz
MTX

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Upgrade your power for better sound

You'll get some serious MTX bass mojo when you put the MTX THUNDER500.1 mono amp in your car. This compact amp will drive your subwoofer setup with up to 500 watts RMS. Hook this amp up to a nice set of subs, and you'll hear sounds you've never heard before, even in your favorite songs. And this little bruiser wil truly fit in places where amps don't usually go.

You can adjust the low-pass filter and subsonic filter to get the best possible sound from your sub and enclosure. In the unlikely event you want to bump up the bass a little, you also have access to a selectable bass boost.

Features

Overview: The MTX Thunder500.1 is a mono Class D subwoofer amplifier. It has aluminum heatsinks to dissipate heat generated by the amplifier. The amp produces 300 watts RMS x 1 at 4Ω and 500 watts RMS x 1 at 2Ω.

Gain: The amp's rotary gain control is continuously variable from 200mV to 5V to match the output of the source unit.

Protection Circuits: The Thunder500.1 provides protection against overheating, under voltage, and electrical short circuits.

Crossovers: The amp features a built-in low-pass crossover, with a continuously variable cutoff frequency of 40-220Hz; the crossover cannot be bypassed. Additionally, the amp has a subsonic filter to remove ultra-low frequencies, thus minimizing wasted power and protecting speakers not capable of reproducing those frequencies. It has a variable crossover frequency of 20-50Hz.

Bass Boost: The Thunder500.1's bass boost circuit is centered at 50 Hz. It can be set to 0dB, +6dB, or +12dB.

Electronic Bass Control (EBC): An Electronic Bass Control (EBC) module is available directly from MTX that allows you to adjust the bass output of the amplifier from the front of the vehicle.

Connections

Power Terminals: The Thunder500.1 features set screw terminals for power, ground and remote turn-on. The power and ground terminals will accommodate up to 4 AWG wire, while the remote turn-on terminal will accept up to 10 AWG wire. The set screws are loosened/tightened with the supplied Allen wrenches. MTX recommends the use of 4 AWG power and ground wires.

Note: The Amplifier is not equipped with an internal fuse. An external 60-amp fuse (not included) must be installed on the power wire. If the system has only this amp and a wiring kit is used that includes a fuse with a value other than 60-amps, the original should be replaced with a 60-amp fuse.

Speaker Connections: The amplifier is equipped with two pair of set screw terminal speaker outputs. The outputs are internally wired in parallel, making it easy to connect two subwoofers. Each terminal will accommodate up to 10 AWG bare wire and is loosened/tightened with the supplied Allen wrench.

EBC Port: The amp has a 3.5mm mini-jack for plugging in an optional Electronic Bass Control (EBC) module, currently available directly from MTX.

Warranty

5 Year Warranty Terms: MTX products purchased on or after January 1st, 2013 carry a 5-Year Prorated Warranty with the following terms:

  • Years 1-2: Products found to be defective in materials or workmanship during the first two years will be, at Mitek's option, repaired or replaced by Mitek at no charge. The warranty period does not renew, but continues on from the original date of purchase.
  • Years 3-5: The purchase price of an item which becomes defective after the first two years and prior to the end of the warranty period will be prorated and credited toward the purchase of a new MTX product. The amount of proration is determined by dividing the original purchase price by the number of months in the warranty period (60), then multiplying the result by the number of months remaining in the warranty period.

Awesome amp for a great price. I have it powering a JL Audio 10w6v3 and the amp does just fine. I set the gain with an oscilloscope and after calculating the voltage with the speaker ohm level, the amp is putting out 548 watts RMS with no clipping.
Pros:
Excellent value. Powerful.

The little amp that could...

Written By RubenN, Los Angeles, CA on Tuesday, March 04, 2014
Crutchfield Customer Review (What's this?)
 
My MTX 500.1 mono amp is paired with a 10'' Alpine Type S in a ported box at 2 ohms and it POUNDS. The amp is as small as they could possible make these things which was the main reason (along with the price point) for choosing this amp. Having owned an Alpine mono amp of the same wattage, this one seems to hit a little harder. Having to turn up my system for over an hour of bass-heavy tunes, this amp was warm and didn't break a sweat.
Pros:
- Small size - value in power output
Cons:
- No remote bass controls (hardly a CON)

Small price, big punch

Written By Stan, Baton Rouge, LA on Thursday, January 23, 2014
Crutchfield Customer Review (What's this?)
 
I have this mated with a JL Audio 13" TW5-3 3-ohm sub in one of their StealthBoxes and a Pioneer AVH-X1500DVD head unit. The speaker handles up to 600W RMS and this beast of an amplifier slams it with the gain set at about 1/3 of maximum and the bass boost (has settings for 0db, 6db, 12db) at 0db! The bass response is tight and fairly flat all the way down to the lower registers. It is rated at 300W for a 4-ohm load and 500W with a 2-ohm load, so I'm guessing it's rated at about 400W with a 3-ohm load (Manual doesn't specify output for 3-ohm load). But it seems like this amp may be underrated on power. Small footprint and unbelievable price tag for an amp this good. I've heard (never owned) other MTX Thunder amps in the past and they've always impressed me, but the price tag of this one raised a flag. I read the mostly positive reviews and decided to take a chance, and I'm 100% convinced I made a great buy. Runs cool, even at pretty loud volume. If you need solid, clean power at a very reasonable price, this is the amp for you.
Pros:
Small footprint, clean sound, powerful!
Cons:
It wasn't free

The only thing that I can compare it to is dynamite. They are both small, very powerful, and way under rated! Running one JL 10" sub rated at 300 watts rms and have to turn the gain way down and bass boost off. Could very easily run another one. Sound quality is great and lots of tuning capabilities. Would purchase again in a heartbeat!

This amp really surprised me!! I paired this up with my alpine Type R 8" sub. A little more power than my amps require, but that is a good thing and it works darn near perfectly together!! Stays cool, easy to install and doesn't take up too much space.
Pros:
Has subsonic filtering, stays cool, price compared to others. Plenty of controls to help you hit the sweet spot.
Cons:

Solid build, compact, good power

Written By Scott, Nashville, TN on Friday, August 23, 2013
Crutchfield Customer Review (What's this?)
 
This amp is even smaller than you expect once getting it in your hands. However, while the footprint is small, it still is over 2 inches high and is quite heavy. Connections are all solid and the look is very clean. Appears very well built, for the price it is massively overbuilt. Power output is as advertised and it seems to run well under continuous load - doesn't get too hot.

I initially hooked it up to a shallow sub with very low sensitivity and it was underwhelming. However, substituting a pair of more traditional 10's it proved the limitation was the sub, not the amp. It pounded the 10's! Looks like if I stick with my current, self-imposed space restrictions I will need to either add a second shallow 12 or switch to a couple traditional 8 inchers that will make much better use of this amp's power. Bottom line - an incredible deal for the price and just a very nice amp overall.
Pros:
Size, build quality, power and installation flexibility
Cons:
None so far

Great value

Written By telekaster, San Diego, CA on Friday, July 12, 2013
Crutchfield Customer Review (What's this?)
 
I'm using it to drive a JL CP108LG-w3v3 subwoofer/enclosure. It's a great match. This is one of the best values on the market when you shop for comparable amps.
Pros:
Great price. Small size. Good power.
Cons:
The optional accessory external bass control (EBC) is no good at all. All the adjustment is within the first 10% of knob travel, then it's FULL BLAST past that point. I purchased and returned it to MTX after testing it out. I went with an RCA-based gain control. The full range of the knob is usable with that unit. The amplifier itself is great.

Bought many many amps in the past and this thing should be put up next to the best. The price is deceiving and the pictures even more. This amp is tiny, but the footprint it leaves is huge. Currently pushing a 12" pioneer premier spl 3000 in the bass bunker sub box thats also here on crutchfield and man does it pound. Only thing it needs is a bass remote included.

Small size, price, wattage output, sound

MTX Thunder500.1

Written By Williams, Las Vegas NV on Tuesday, May 21, 2013
Crutchfield Customer Review (What's this?)
 
Good little amp. Currently running two 10" Kenwood KFC-XW10's. Granted, the subs are rated for more than the amp can produce but it makes the subs pound hard. I have the new Kenwood KDC-X797 head unit and they both pair up pretty good. The amp is strong. It gets pretty warm on me when I have the music turned up and may have shut off on me once but I am not sure if that is what happened cuz it hasn't happened since then. I have done the Big 3 upgrade on my Honda Civic with 4 awg cables and with the volume up loud I do get the headlights to flicker a little bit on my 80 amp alternator. So... it's not drawing a terrible amount of power.

Just got the EBC bass control to control the bass with a remote knob rather than through the head unit (that's annoying) but haven't hooked it up yet. Just adding this in to let you know that it offers this feature.

You may be able to find a better price for the amp than from Crutchfield, but that is not to knock Crutchfield, they stand behind their products 110% and the Customer Service is worth the extra $.

For a low cost bang for your buck subwoofer amp for your small stereo system I would definitely recommend this amp for sure.
Pros:
small, good power, loud, good price. It's MTX and I have always liked MTX amps.

MTX Thunder500.1

Written By Boscorilious, Laveen, AZ on Sunday, April 28, 2013
Crutchfield Customer Review (What's this?)
 
I needed an mono amp to power a 12 inch Kicker subwoofer. This amp did just that. It was incredibly reasonable and easy to use/install. As a Class D amp it runs well in closed spaces within little air circulation. It's been hard at work for 2 days now and so far no complaints.
Pros:
Everything about the amp is great. At this price point, not all amps give you the ability to manage bass boost, gain, LPF, or subsonic. Great power at 500W, peak 1000W, it's an amp that's hard to beat.
Cons:
Instruction manual is not easy to use. Since this was my first amp/sub install, I relied heavily on youtube videos in order to tune my amp.

Don't shy away from this amp because of $$$

Written By DougB, Nashville, TN on Monday, April 22, 2013
Crutchfield Customer Review (What's this?)
 
So Im relatively new to Crutchfield but a friend recommended. I upgraded my daughter's vehicle factory sound system (2000 Ford Expedition). I installed a new head unit (Kenwood, awesome), 2 Polk Audio 12's, and to push the 12's I purchased this amp. OMG.....this thing absolutely pounds. I was so shocked when I installed this unit that I actually had to make sure they sent me the right amp. I wired the 12's down to 2ohm and this amp just pounds them. ITs a very clear sound, no distortion at all, and I haven't even begun to push them. I have the amp boost to 6db and likely will turn it down, I have the gain about quarter of the way up and it will blow your mind. Im telling you, if you want a setup with 10's or 12's and you dont want to spend a ton of money, you need to buy this amp.
Pros:
Sound Quality Power Easy Installation Small, will fit anywhere
Cons:
No fuse, but this is not a big deal. My amp wiring kit came with an inline fuse so its no big deal at all...Infact, I'm embarrased to put it as a con.

This thing is physically small so I was a bit concerned when I unboxed it. Installed it to power my Kicker CompVR 10" wired for 2ohms. Sounds just as good as my previous Kenwood 8105d amp that died on me. Also I dont notice it getting very hot at all when making it work hard.
Pros:
Should fit it any application Runs Cool for small size Allen head screw type terminals

Great amp and good price, Very small for the power. Works great on my Kenwood 10's. 4 gauge connections. Gives you connections for 2 subs so you don't have to daisy chain them or try to stuff 2 sets of speaker wires in the same hole. Very pleased with amp will be buying another for my 12's. Just remember to buy a fuse block for it does not come fused.
Pros:
Super small, plenty of power, great connections
Cons:
not fused.

Great size! Mounted it right to sub box. End pieces come off, I painted them to red match sub grills. Nice touch! Just make sure you sand them real good so paint sticks.
Pros:
Compact
Cons:
None

Can this amp run at 8 ohms? I'm doing a experiment with my thunder series 5512-44 sub and on 2 ohms the amp will clip without much(gain, boost, etc). So if this amp will be stable at 8 ohms what would be the RMS? Thank you [ MTXaudioUser  Feb 28, 2014 ]

  • Thanks everyone for the answers. I wired it at 8 and amp runs cool, sound is great and still haven't done tuning to the head unit. Also clipping even at max level before distortion is gone, I'm using a clarion cz-102 so 35-37 is prime max level. Going to be working on tuning the parametric eq, sub level and magna bass. Oh and the vehicle is a 02 Silverado ss, single cab. Sub is in a custom sealed truck box with a little under 1cubic ft(smaller then recommended but quality is great seeing as box was tuned for super low frequency). Currently running a small 10 awg wiring kit with fuse that came with the truck, next upgrade is a 4 gauge kit and a capacitor just to ensure the clipping at 2 ohms wasn't a power-related issue. As is the sound quality is outstanding and as usual MTX didn't disappoint, kicker components are working ideal and taking the risk trying out clarions new line of decks was not a bad idea.

  • This amp can operate fine with a 8 ohm load, but I have no way of knowing the power output... I would guess that it would be in the 200 watt range.... [ GREG   Mar 03, 2014 ]
  • Yes it will run @ 8 ohm fine. I am curious about the amp clipping with the 2 ohm load. Have you measured the resistance of the speakers to verify the load is 2 ohms? This amp works fine @ 2 ohm provided the input signal is NOT LINE LEVEL. Typically if you are using line level the distortion causing the amp to clip is coming from your head unit's less than desirable amplifier sending it downstream. Output @ 8ohm = 160 RMS (rough estimate didn't do the math) [ GREG L   Mar 02, 2014 ]
  • No it will damage the amp. [ REGINALD O   Mar 02, 2014 ]
What is the best way to hook my wires up to the amp? [ Matt  Dec 28, 2013 ]

  • I have this amp pushing two rockford fosgate dual coil 12's that are wired in a 2 ohm circuit. The best way to wire this is solely going to depend on your subs. single or dual coil? system was installed by a professional shop and I went ahead and bought a pretty beefy wiring kit to make sure the components were going to last even if I decided to go up to about 1000W at 2 ohms. Right now it's only 500, but meh, I like the way it sounds and feels so it's all good. If you aren't sure what you are doing might could take it to a car pro shop and ask for advice or search around on forums? I looked at a bunch of forums before I decided to just spend the 150 bucks to have the amp&subs fully installed by the place(including the 80 dollar 4 gauge and 12 gauge wire compenent kit with a fuse and everything). [ PRESTON   Jan 18, 2014 ]
  • There are hook ups for the wires on the back of the amp itself. As far as placement, it's more of a question of personal preference. Some people like to wire the amp up in the trunk. I prefer mine under the passenger seat, that way I can adjust it without having to dig around in my trunk. [ Syrus   Dec 30, 2013 ]
  • If you're already on the internet all you have to do is look it up. In fact, Crutchfield has articles that can help you. (http://www.crutchfield.com/learn/learningcenter/car/amplifier_installation_guide.html?g=100). Google "basic car audio electronics". It will link you to a site called bcae1. It is a very god resource. [ JUSTIN   Dec 30, 2013 ]
  • I'll try to awnser best I can. Which wires are you talking about? Power wires, signal wires form the radio to the amp, or speaker wires. I ran my power wire from the battery under the car, along the frame and up thru the floor where I mounted the amp. Using an inline fuse near the battery and one close to the amp because the amp is not fused. The blue wire to turn the amp on and the RCA cables I ran along the door sill. ( if you run the power beside the RCA cables you will get an annoying buzz or whine in the speakers. ) I hope this helps. There are also wiring diagrams with the amp if I remember correctly that will show you where the wires connect to the amp. And if all else fails the tech people at Crutchfield are awesome and can walk you thru it. I put that amp in my daughters jeep liberty and have been more than happy with it :-) [ GEORGE   Dec 29, 2013 ]
  • Umm no clue I did it a while ago... Haha sorry man! [ JORDAN M   Dec 29, 2013 ]
  • The correct way [ JEFF   Dec 28, 2013 ]
  • Well i used a 4ga for the bat 8ga for ground 16 ga for the remote signal and 12 ga for the subwoofer. Remember the bat cable have to go directly to the battery the remote goes to the blue lead to your head unit and the ground cable should go to a unpainted metal surface in your car. This amp does not have a built in fuse so you need to install a 60 Amp fuse. I recommend closest to the battery as posiible. If you need any more help or pics let me know. Have a good day! [ ERNIE J   Dec 28, 2013 ]
  • With the design of the terminals the best option is to simply strip the ends of your wire and insert them without any additional hardware or preparation. Very secure connection and protected against shorting as long as you strip the appropriate amount (1/2 inch or so) which gives proper insertion depth while also ensuring there is no bare wire extending beyond the housing. If your speaker wire is thin gage you may need to strip a bit more and fold it back over itself to ensure enough thickness for a secure clamp. Other than that, don't waste any $$ on additional connection accessories. [ TIMOTHY S   Dec 28, 2013 ]
  • Well, I'm using a MTX Terminator Series box, and the subs were already installed, all I had to do was buy a wiring kit. [ PETER D   Dec 28, 2013 ]
I was going to buy this amp to power a sub with a range of 28-200 Hz. Will this amp allow me to get all the way down to the 28 Hz that the sub can handle? [ Colton  Dec 25, 2013 ]
3 answers
  • The amp has nothing to do with getting down to 28Hz. That will be limited to your subs, enclosure, and installation. [ JUSTIN   Dec 30, 2013 ]
  • Colton I installed this amp last April to a 8" type-r sub the amp works great, no problems,. Will hit hard if that's what you want. the amp can be adjusted and will do the complete range 28-200 but you need to adjust the sub to your vehicle and how it sounds to you. [ RANDY   Dec 29, 2013 ]
  • It should work fine. Although I'm not sure if your hearing will be able to distinguish it. That getting to the lower threshold oh the human hearing range. [ DAN   Dec 26, 2013 ]
