Here's a few things you can do to find out what's wrong ,first make sure you have 12volt on your batt lead and your remote turn on and make sure you have good ground.Take an ohm meter or a 9volt battery and put across/momentary the voice coil on your good sub should read somewhere between 2-8 ohms,if using a battery speaker should pop.if ohms check out or speaker pops your good connect it to your amps output.Next make sure you have a signal to the amp,if you have multiple amps use the rca cable from amp that's working for testing purpose.if all that checks out you'll need to have your amp check by professional

Have you confirmed that you have a good signal feeding the amp?

Have you confirmed that the speakers are in good working order and don't have any breaks in the wiring?

SOURCE: what do i do when its telling me that its protected.

Over current protection turns on when the amp draws more current than normal. It turns on so it doesn't catch on fire. Your amp has a fault, most likely in the output stages. These power transistors consume the most current and if they blow short then that will cause it to go into protection. If it is under warranty take it back, if not have someone in your area try to repair it. What load were you running anyway?

Amp not working

sounds like the amp is going into protection mode. maybe a sub is shorted (blown). Or, the only other possibility is the mosfet transistors on the inside of the amp are blown.

Have 2 blown square hifonics 12inch speakers. Was playing goos and then just stopped. Took to radio shop and they said I have 2 blown sub-woofers. How can i get them fixed.

They probably will have to be reconed. Slight chance the flex leads have broken in which they MIGHT be repairable. If this occurred during playing very loud, you probably burned up the voice coils.

Have them reconed and then use an amplifier that maxes out at MUCH less power to drive them. Also fuse the speakers to protect them.

HiFonics txi4008 not working, partially lighting up

Sounds like your amp has some power supply compents shorted out. Maybe some of the power mosfets are shorted and your only getting a little bit of power. That why only the H is lighting and as far as the green light, it don't take much for it to turn on. If it was major it would go into protect mode but it is'nt. I repair amps for a living and I'm the cheapest you'll find. But if you know about electronics and think you can take a crack at it, check it out. Becareful you could do more damage. Let me know if your interested. [email protected]

Okay i have a problem hifonics brutus 1500 mono d class amp

well your amplifier is obviously going into protect mode,(i used to have this amp and it is awesome) anyway i would go through just to be sure and check all the power connections with a test light, remote wire, positive, and ground. and check the fuse to see if it is still good. you can buy a test light at wal-mart and any automotive store. if you stil have a problem then i would check to see if your running below 1 ohm on this amp. that would cause it to go into protect mode. if all this fails i would just go buy a new one.
