Hey guys, I recently acquired a Hifonics Brutus 1500d from some kid on a car forum. Anyways, when i got it it worked fine. However, when i installed it, i did it in the dark, and I tuned it wrong. apparently i had the gains set way too high, blew up 3 speakers before thinkin about checking my settings on it. So, after that I put in a different sub, and it worked for a few minutes, literally. It gave out 10 minutes after installing the sub. Its all lit up still, but no sound comes out. The only time sound comes out is when the car is left off for a long period of time, and then its a short 10-20 second burst of bass, then nothing. any one have any ideas? sorry this was long.

Amp Troubleshooting POWER
STEP 1
A: Check for 12v at amp using the amps ground, if correct move to step 1-B
If not 12v,check again using a good ground
If still no power, check fuse on both sides of the batt.
B: Check for 12v Remote power using amps ground, if correct move to step 1-C
If not 12v, check remote power behind deck.
If still no power connect to a accessory power source.
C: Check amps ground, If amps ground is good,and it wont power on, Amp is bad. SIGNAL
STEP 2
A: Check Rca's output at the amp for AC voltage (0.5v-8v) and should change
w/ volume, If correct move to step 3-A
If there is no voltage move to step 2-B
B: Check for AC voltage at head unit (0.5v-8v) and should change w/ volume
If correct, Rca's are bad and need to be replaced
If there is no voltage at head unit, deck is bad and needs to be replaced OUTPUT
STEP 3
A: Check the positive and negitave terminals at amp for AC voltage should
range from (5v-40v) and change w/ volume.
If there is power, check speakers for correct ohms
If speakers are correct then the amp is bad and needs to be replaced sS https://www.the12volt.com/installbay/forum_posts.asp?tid=78593&KW=spookiestylez ------------- RTFM
