SOURCE: JBL Sub Amp Wiring Please

it seems rather redundant to bridge a mono amp. Unless the instruction manual states otherwise, i would assume that one speaker output is identical to the other (ran in parallel, like an A or B speaker, not like Left or Right), and you would present the amp with a two ohm load by wiring one speaker to each output. Bridging it may or may not work, but, again, it just seems redundant.

Actually I buy them in lots of 1000 and I pay 38 cents each for them. They are 24k gold plated. They are the real deal. If you do the math you can see I do not make much of a profit at all on them.

no you cannot substitute a 680uf 16v 105c in place of a 1000uf
if you want to put a better capacitor in place of the old 1000uf 16v 105c , then use a 1000uf 25v or 35v 105c
the voltage rating will allow the cap to better handle the circuit

SOURCE: JBL amp, worked fine untill 2 days ago. protection light on..

might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.

you will need to disassemble the entire amp, check all components and replace burned ones.
some components burn when wrong polarized.

Protect mode is on what could be the problem its not fuses checked that


There could be a number of reasons the protect light is on. Blown speaker, blown amp, overheating, ohm load is to low and the amp not stable, ect.... Start by checking all of your connections, then if you have a DMM set it to the ohm setting and check each speaker connected to the amp. If its a 4 ohm speaker the number should be around 3.5-4.5 (the #'s can move) If the # jumps all over the place then the speaker is fried. And don't forget to check the ground...it can cause all kinds of problems...hope this helps

I have the JBL gto 601.1 apm its a 2 channel, i hook them up to 2 12 kickers, the amp will play the subs properly ONLY at low volume and the amp will spit and choke on high volume ( meaning that it will go...


ok first off bbbman78 is wrong!!! second off that amp is not a 2 channel amp!!!! i have the exact same set up as u do. an i was having the same issue. i discovered that the subs were not wired to the amp correct because the amp is a class D mono amp. and it does have 2 sets of terminals to wire subs to, but it is actually a 1 channel amp! ok if u have the 2 ohm dvc (dual voice coil) wire them like in this linkhttp://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/2DVC_2-ohm_mono.jpg
if u have the 4 ohm dvc wire them like in this linkhttp://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/2DVC_4-ohm_mono.jpg
once u wire them correctly.....crank it up and enjoy!!

JBL GTO 301.1ii protect mode


Hello roets81,

Check the voltage at the amp. It's possible that the voltage is either too high (above 16V) or too low (below 8.5V). Also make sure that the amp case is not grounded. If these check out OK, the most likely cause is that the amp itself is defective and requires service.

Hope this helps.

Jbl gto 75.4 right channel not working


Hi

It's rare that 2 channels will fail simultaneously, are you sending 4 signals to the amp or just 2?

If you are sending just 2, perhaps the problem lies before the amp in the cabling to it, or the output from the headunit. If you are sending 4 signals then there may be a fuse in the amp that drives 2 channels out of the 4. Of course this may be the case should you just be sending 2 signals.

My Jbl mono amp cuts out


It's likely that the amp has blown output transistors. To eliminate other possible problems, read through the following page:

Amp Going into Protection Mode

Let me know if you have any other questions.

Blown capacitors


There's hundreds of capacitors in an amp... The value should be printed right on them. It will have a Farad rating (F) or usually MICRO farad (uF) and a voltage rating (V). Looks like "16V 47uF"... Be aware that there's likely to be more problems than just the caps...
