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.

Would this be a good match for 2 svc 4 ohm subs with 250 rms rating?
jourdan  May 10, 2021

If the subs you are talking about are 250 watt RMS each, then yes this amp will work if you wire the subs to 2 ohms at the amp. Hope this helps.

Q
Would this work with a rockford fosgate P2D2 15?
alexander  Dec 16, 2020
2 answers
A
Yes, It would work, but you would have to run the dual 2ohm voice coils in series because the amp is only stable down to 2 ohms. It would be better to get a dual 4 ohm sum so you can run them in parallel for a 2 ohm load.
ken  Dec 17, 2020
A
Should be fine, but might be a bit underpowered for that sub. That speaker is 400W RMS (Dual 2 ohm voice coils). This amp can do 300W @ 4ohms. That sub would either wire in series (4 ohms) or parallel (1 ohm). I would not suggest this amp in the 1 ohm config, would either run hot or smoke. If you are set on that sub, get the dual 4 ohm coil version, then run in parallel @ 2 ohms. Either that or get an amp that can run 1 ohm stable if you want more power.
eric  Dec 17, 2020
Q
I am looking to buy this amp for my son's car. We have 2 12 in jbl gx1200 subwoofers. Each has 250 rms and 4 ohms. Will this amp work for that setup? Thanks for your time.
kevin  May 03, 2020

A
Short answer is yes, plenty of power. I have been an MTX fan for literally decades. I bought this amp most recently to power one 12" MTX sub for my 2018 Kia Niro. It hits so hard, I have the bass turned down to -2 on the stock head unit.
anthony  May 04, 2020
A
Yes. Wire the subs in parallel so the amp sees 2 ohms and you'll be good to go. The amp is small, but packs a really good punch. You won't be disappointed.
ken  May 04, 2020

We have loved it and highly recommend it. We run a single kicker 12" competition sub and it works great!
robert l  May 03, 2020

We use it for one 12" kicker competition sub in my son's truck and it has been awesome. We have it turned way down and the bass is great. It's small and hasn't run hot at all.

rob  Mar 12, 2016

mike  Mar 12, 2016
A
It'll definitely move them. Mine is hooked up to one 10" kicker cvr. Powered all the way up, with the bass boost down though. Depending how much cash you want to spend. This amp will work and isn't that much cash, the reason I bought it. If you have money to spend I'd go with a larger amp, since you have two kickers. It's a great amp though. Hooked it up last year and haven't had to do anything to it since.

Hi..! I want to buy this amp to combine with the MTX RT10X3DS. The subs are 600 rms at 2 ohm sealed enclosure. If someone have this package or knows about the triple design i would like to hear your opinions for the sound quality. The delivered power from this amp is enough to sounds this box loud? Thanks..

I am using the amp to push 2 JL AUDIO 8's. The amp gives the JL's all that they want. Amp is small easy to install in tight spaces I have never had the subs distort. I liked the amp because it does exactly what I want it to do at half the price of some. I have a single MTX amp running 2 JL Audo 10's ported box and they rock.

Q
Does This amp get very hot? This is a bit of an off roader's question. My brother has this amp and is going to give it to me to put in my Jeep. I take my jeep offroading in the desert regularly. How does the amp do wit heat and dust? What I'm asking is; does it get hot in a clean room temperature car? If it does it will surely overheat in the Jeep.

Mine seems to run quite cool. It lives in the dusty hot enviroment of the back of my cj7. So far so good.
dan  Nov 22, 2014
A
it's an amp. YES it gets hot. YES it has thermal protection just for that. This is a class D amp. screw it down and rock on! IF it gets hot and clips...... Instead of mounting it directly to the floorpan (usual in a jeep) I would recommend mounting it to a piece of 1/4" or 1/2" thick piece of aluminum(to dissipate heat) WITH.... a 1/2" spacer to the floor so you can have air circulation. crank it loud!!

I purchased this amp to use in my boat. It is in the front ski locker and since I've had this amp I have never had a problem with it shutting down due to heat. We use this amp in hot weather and all day long while on the water. Now we don't have any issue with dust on the water. Hope this helps.

I live in new England where it gets hot & humid. had this amp in the trunk of my car & on 95 degree days with 90% humidity I never had any problems with it over heating seems like it was always cool.
bruce  Nov 22, 2014
Q
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
4 answers
A
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.
mtxaudiouser  Mar 04, 2014

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....
bruce  Mar 03, 2014
A
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  Mar 02, 2014
A
No it will damage the amp.

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
A
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 :-)

jeff  Dec 28, 2013
A
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 joel  Dec 28, 2013
A
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.

colton  Dec 25, 2013

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.
