The amp probably has shorted output transistors. The damage may include several surface mount components also. The output transistors are soldered to the mehsa insulator and are more difficult to change than those in other amplifiers. If you want to learn to do repairs, it may be worth the cost and effort to try to repair it. The parts are relatively inexpensive (average less than $15 - not including shipping). The tools to repair it are going to cost ~$35-50.

If you simply want the amp repaired, take it to a local repair shop.

Whats the best way to wire an mtx thunder152 to an jl audio 12 w3-d6 duel voice coil sub


Take both positive leads to the positive of the amp. Both negatives from the sub to the negative of the amp. Utilize the bridged output connections. This would present a 3 ohm load which would be around 100 watts rms (rough estimate)

How to wire a crossfire vr602 2 channel amp at 4ohm and 2ohm


I would be more worried about the amp than the speakers, those subs should handle the watts with no problem. The problem will be in the amps ability to remain working with a bridged 2 ohm load. It may not even stay on without going into protect mode with a 2 ohm load. If it does stay on then it may get really hot and shut off from the heat off of the Mosfett Transistors, or it could burn the Mosfetts from driving them too hard. Basically it's your choice, run your amp hard and gain more volume or run it with slightly less sound and have a cleaner sounding more stable amp that will stay on and have less chance of being damaged. If it's not loud enough the best thing to do is buy a different amp that better suits your needs and fits the application. In your case a 2 ohm stable Mono amp is going to be your best bet or a 4 channel amp bridged into 2 channels and run with 4 ohms on each channel. Or another exact matching amp like your 2 channel amp bridge them both and have each powering 1 of your 4 ohm subs. I used two VR mono amps to power my two 12" 4 ohm subs for a few years

JL Audio Amp. My amp all of the sudden started cutting in and out. It's an older amp and I've never had issues with it before. I've checked all the wiring and the fuse it all seems fine. Any...


you need to determine what impedance the amp is running at ,how many spekers ,most 2 channel amps will only run 2 4 ohm subs per channel and only 1 4 ohm speaker in bridge ,Basically if you have 2 4 ohm speakers bridged at the amp it will usually cut in and out .Some amps will not do this for a while and will work for a while at low impedance but once they get older and hot and cool off many times they will then only work for the intended ohm load ,Do you have 2 speakers ,if so make sure 1 is on left channel and 1 is on 2nd channel (should not cut off ) if it is a mono amp ,make sure you are only running 2 4 ohm subs and not dvc speakers (these will run 1 ohm and shut the amp down ) there are ways of wiring more speakers or dvc speakers ,I can explain but I need to know what product you have .

Hello. I have one (1) XS-L1035 being powered by a JBL gts 180X 2/1 channel amp. The sub works fine if i power two(2) subs thru 2 channels BUT if I try to bridge the power to one sub the amp cuts out. Is it...


It sounds like the problem is with the amp. try using the other sub in bridged mode and see if it still turns it off. If it still turns off then its definitely the amp. In 2 channel mode you are using each channel at 4 ohms right? and in bridged mode to 1 speaker it should be throwing a ton of power on a 4 ohm load as well,it should work fine bro -its gotta be the amp

My amp is protecting unessacarily when ran at 2 ohms


are you factoring the ohm rating from running them parallel?

2 x 2o subs parallel = 0.5 ohm (lowers ohm's)

2x 2oh subs series = 4 ohm

IT is posable that you are calculating the ohm rating fine, BUT some SUBS can reach lower ohm rating while hitting bass- i didnt know this till i had a rather insane sub that would dip to 1ohm while hitting hard bass causing my amp to go into protect mode.

Is a 15 w3 d-4 better then a jl audio w3-d2


Hello,

All of the JL W3 subwoofers are essentially the same. The "d2" and "d4" suffix refers to the voice coil configuration. "d2" = dual two ohm coils, "d4" = dual four ohm coils. Depending on the number of subwoofers in your system and the amplifier(s) you are using to power them, one or the other of the configurations may be "better".

Generally, you want to have the load on your amp to have the lowest possible impedance consistent with the amps capability to operate properly with that load. It's normally referred to as "impedance matching". Greater power (watts) is produced, and louder sound, when the amp can deliver power at a lower impedance.

If your amp is only capable of supplying power at 4 ohms, you want to make sure that the configuration of your sub(s) represents a 4-ohm load. If the load is higher, say 8 ohms, then your amp can only deliver about half the power of which it is capable. It would be OK to run them a 8 ohms, but they would not be as loud. On the other hand, if the load was lower, say 2 ohms, your amplifier would soon overheat and go into protect mode.

So the trick is to first decide on how many subs you want. Then choose an amp/sub combination that "matches".

The DVC or dual voice coils just gives you more options in selecting and configuring. Say you want 2 subs and you are going with the 15w3 d-2. Your amp is the JL Audio G-MAX monoblock. The amp puts out 1200Wx1 Chan. at 2 ohms or 600Wx1 Chan. at 4 ohms. You would wire both of your subs voice coils in series making each sub 4 ohms, then wire the 2 subs in parallel to your amp making the final load 2 ohms, the best "match" for your amp.

You've pretty much hit the nail on the head. Two 2 ohm subs in parallel would give you 1 ohm, and two 2 ohm subs in series would give you 4 ohms. 1 ohm would be overloading the amp but 4 ohms is slightly "underloading" the amp.

Your best solution with the gear you have (i.e. not buying new subs or a new amp) is to put the subs in series (4 ohms). True, you'll be putting about 200W into each sub, but according to page 4 of the owner's manual for the subs, 200W is just a tad under the optimum level recommended for the sub anyway.

3 ohms per channel or 6 ohms bridged are the only options. 3 ohms per channel is a better option.

500watts sounds about right to me,i wouldnt go any higher as you risk popping the sub and haveing a melt down in the coil section of the subwoofer.
