THUNDER 5601 WHEN VEHICLE TURNED ON, SUBS BOOM, THEN WORKS OK. ALSO WHEN RADIO TURNED OFF

INSTALLED MTX 5601 WITH INFINITY DUAL VOICE COIL SUBS. IN SRT-4. WHEN VEHICLE IS TURNED ON AMP IS POWERED UP, THE SUBS BOOM LOUD TILL THE MUSIC STARTS. IT WORKS OK AFTERWARDS. THEN WHEN VEHICLE TURNED OFF OR THE RADIO IS TURNED OFF, THEY BOOM REALLY LOUD TILL THE AMP POWERS DOWN. THE AMP REM IS COMING OFF OF IGNITON WIRE FROM FACTORY HEAD UNIT. DID NOT INSTALL A LINE OUTPUT CONVERTER, RAN RCA JACKS FROM AMP TO REAR SPEAKERS FOR SIGNAL FROM RADIO. VEHICLE HAS FACTORY KICKER 'LIVIN LOUD SYSTEM IN IT. EMAIL [email protected]. THANKS!!

If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.

Let me know if you have any other questions.

I have 2 different subs in one box, a 12" MTX thunder and a 12" Kicker CVR. the kicker is a dual voice coil while the MTX I dont believe is. Can I use one amp for this set up? And how would it be wired?


im guessing both speakers are 4 ohms ..mtx 4ohms and kicker dual 4ohms..now if your amp can go down to 1 ohm wiring the kicker dual coils in parallel (2ohms) and the mtx connected together (4ohms) should leave you with a final impedance between 1 and 2 ohms ...i suggest you use one or get another

I installed the MTX Audio JackHammer JH300 600W, Class D in my truck. Powering two alpine type-s 10' subs. Im using a 50a fuse at the battery. 8 gauge B and ground. I had the subs working went for a drive...


Your amp should not have a 50 amp fuse at the battery. It puts out 300 watts RMS (continuous power). The fuse at your battery should match the one that is on the amp itself. Your amp is overheating and there is a fault, possibly your speakers are wired to present too low of an impedance to your amp. Disconnect them from your amp, and use an ohmmeter/multimeter and measure the resistance load. It should not be lower than roughly 2 ohms. Depending on whether you bought dual 2 ohm or dual 4 ohm subs, that could be the heart of your problem.

If you bought D2 subs, you can get a 4 ohm load per sub with each sub's voice coils in series, and then parallel them together to get a 2 ohm load at the amp, which is perfect for your amp. Or you can wire each sub's voice coils in parallel, so that they're 1 ohm each, and then series them together at the amp for a 2 ohm load. The first method is simpler. Be sure that you haven't wired each voice coil in parallel (1 ohm per sub), and THEN also wired both subs in parallel to the amp (1/2 ohm load). That would definitely send your amp into protection mode, probably before it would have a chance to overheat. This is another reason why you should not have used a 50 amp fuse under the hood. If for whatever reason, the fuse on your amp doesn't blow, the amp is getting way too much current for it to handle, because of that 50 amp fuse under the hood.

If you bought D4 subs, you have a problem. If you've wired each sub's coils in parallel (2 ohm per sub) and then wired both subs together in parallel at the amp (1 ohm load) you're presenting too low of a load to your amp. Again, this will overheat your amp and send it into protection mode, both of which are what you're seeing. You never want to have two D4 subs with an amp that only handles 2 ohms, because you can't get a 2 ohm load with two D4s. You're stuck with 4 ohms or 1 ohm. 4 ohms cuts your amp power in half, 1 ohm cuts it off completely.

If you know for sure which way you've wired them, then you now have the information to tell you whether you've done it incorrectly or not. If you're not sure, first disconnect your subs and measure the resistance as I described in the first paragraph. If your amp is seeing a 1 ohm or 1/2 ohm load, there's your problem. If you see a 2 ohm load (subs are wired correctly after all) then you may have a bad ground connection, or your amp is bad and needs to be serviced/replaced.

Need to know how to wire my system ...I have the infinity reference series 611a I was told it was a mono block but it has two channels on the exterrior...also I have two 12 inch MTX thunder dual voice coil...


it all depends on what kind of box the mtx subs are in as far as wiring the subs. The best way would be take the speaker wire from both sub boxes and run the positive into the right positive then the negative into the left negative. and run 8 gauge wiring kit to the amp because 10 might be to small and 4 is to big 8 gauge is perfect for this amp.

How do i wire a mtx 251d at a 2 ohm load


To wire up a 2 ohm load depends on the subs. You will either need 1 sub rated at 2 ohms or 2 subs at 4 ohms wired in parallel. This website will help.
http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=41#results
You can also use 1 dual voice coil sub rated at 4 ohms wiring the same way you would the 2subs at 4 ohms. Good Luck

Can you help with my wiring?


The more amp you are pushing the better. Better too much amp then not enough. How many watts per speaker? less then the amp I hope. When you need decibles the more air you push the louder it will be. Enclose in a MDFB enclosure or plexiglass and feed towards each other and port the box to the sides. This will cause some annoyance. We ran 2 rockforts @1000 watts and abtained 137dc before the back windshield blow out,,lol

How do i wire mtx 9500 subs 2 10'' down to a one ohm


THE T9510-04 SUBS ARE SINGLE COIL SUBS AND YOU CAN VIEW THAT WIRING DIAGRAM AT THE FOLLOWING LINK:
http://www.mtx.com/caraudio/products/subwoofers/TechData_T9510-04.pdf

THE T9510-44 SUBS ARE DUAL VOICE-COIL SUBS AND YOU CAN VIEW THAT WIRING DIAGRAM AT THE FOLLOWING LINK:
http://www.mtx.com/caraudio/products/subwoofers/TechData_T9510-44.pdf

SINCE YOU NEED A 1 OHM LOAD, I PRESUME BRIDGED AND ARE USING TWO SUBS, THEN HOPEFULLY YOU HAVE THE DUAL VOICE COIL TYPE, AS THEY ARE DUAL 4 OHM AND YOU WILL HAVE TO CONNECT THE VOICE-COILS IN PARALLEL WHICH WILL MAKE EACH SPEAKER A 2 OHM SPEAKER AND THEN CONNECT THE TWO SPEAKERS THEMSELVES IN PARALLEL AND THIS WILL PROVIDE YOU THE 1 OHM LOAD. IF YOU IN FACT HAVE THE SINGLE 4 OHM VOICE COIL VERSION, THEN IT WILL ONLY PARALLEL THE PAIR DOWN TO 2 OHMS. OK. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

Infinity 1600a cuts out wit real low bass when turned up load



With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts on either terminal when you drive the amp hard, you need to check the wiring feeding whichever line is dropping too low.

Subs


I looked up that amp, it doesn't have a listing for 2ohms x1 but it has 2 ohms x 2 and its at 250watts. For this situation, I would recommend a different amp or different subs. Right now you are getting the most you can get out of your sub/amp combo, if you only have single voice coil subs. Which is common in the mtx preloaded boxes. Either you want an mono block amp stable at 2 ohms or 2 dual 4 ohm voice coil subs. If you got the subs you would wire the voice coils in series so you could get 8 ohms then the subs in parallel so you could get 4 ohms, which would be the best for that particular amp. Good luck.

I do not hear any music through my 10" M Audio Subs (M Audio Sound System)


If you know how to use a multimeter, you can test the amp this way:

-unhook the subs
-hook up a cheapie speaker you know for sure works to one of the channels
-unhook the audio inputs
-turn the amp on
-set your meter to VDC
-put the positive probe on the inside of the input connector, being sure you make contact with th inner contact
-take the negative probe and tap it on the outside of the connector

What you are doing is sending a low voltage (replicating an audio signal) into the amp audio circuit and allowing the amp to amplify it. If the amp makes the speaker pop each time you strike the probe, the amp is working.

You mentioned you need a 4 channel amplifier make the two, dual voice coil subs operate. The is not true and by hooking them up like that, there's a chance of damaging the subs. The reason is that the dual voice coils are interwoven and they have to get electrically identical signals or they fight against each other. The can mechanically fail, then, electrically fail, then even damage the amp too.
