I've had similar problems, usually for me it ends up being a bad ground.

Yes it possible that the inputs have been damaged on the circuit board of the amp. If the amp has hi level inputs you could try running a speaker wire input to it and see if it works. You might try another pair of rca cables to.

the amp it going into protect mode because there is an internal fault with the amp. it will need to be repaired. best this to do is find a repair shop and let them handle it good luck man

The audio amplifier IC´s maybe are fried

Specs say it depends on the impedance of the speakers. https://www.jlaudio.com/products/jd250-1-car-audio-amplifiers-98360 https://www.google.com/search?q=jl+250%2F1+amp.+Wiring+diagram ..

Sounds like you either shorted something out or overloaded the amp. Is there any odor coming from it? If so It will need to be repaired or replaced. What did you have connected to it and how was it wired?

sounds like the amps not rated for the resistance tha subs have it running at....are they a dual 2 or dual 4 ohm?is the amp rated for 1ohm? sounds like amps going into protect mode

In your world, what does best results mean to you. how are the hifonics mounted? open air, closed box, vented box (optimized to what freq)? trunk or inside vehicle? all these variations weigh heavily on your configuration. As does what 'best results" means to you.

Check your ground to make sure it is properly grounded

Disconnect all the speakers one at a time and see if it stops doing that, if it does you have a shorted speaker or wiring

Amps that big are usually fused on the feed wire, under the hood of the car, near the battery.

You will need to open it up to see if anything damaged. That does not look good at all from the outside.

Re tune your amp

Check your speakers wiring to make sure they are not touching. This will make your amp go in protection mode.

Here's the Datasheet on the TDA7297 IC: http://pdf1.alldatasheet.com/datasheet-pdf/view/25110/STMICROELECTRONICS/TDA7297.html This should work for you. It also shows a recommended circuit for the part.

they are most likely stretched out. try messing with the equalizer to make the sound more crisp.

Fried the outputs

Hi rodneybarton The problem of your unit may be its amplifier. You need to open the box and inside of it, there is a component that attached on the heatsink you need to replace that one. or better send your unit to qualified technician.

Unlikely maybe going downhill with a good breeze.
