20 Most Recent Hifonics Brutus BX 1505D Car Audio Amplifier Questions & Answers


Check power supply diods. power supply capacitors and power supply and output transistors.
Remember, distortion is the biggest killer of subs and amps. Everything made by anybody has its limit.

loosen off the remote wire screw, you may need to strip some of the wire insulation back, place bare copper wire under screw and tighten screw back over wire

Without actually seeing the components your are describing I am only speculating however they could be a type of Film capacitor. Judging by where the location is I wouldn't think they would be power resistors because they are located next to the electrolytic caps for the power supply. They could possibly be coupling capacitors but due to the location I doubt it. If you can remove the fets from the board I can tell you how to test them, just look at the part number so i know what it is. There are also many tutorials on testing FETs on the net you just need a multi meter.

You need to measure the voltages at the output transistors. The previous "driver" stage may have a problem. These outputs use .6V as the bias differential. Check for DC voltage on the inputs to the transistors. These are standard designs. I'd check for DC anywhere along the signal path.

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.

The positives are connected together and the negatives are connected together. The two pairs of terminals are for convenience. You'd connect one speaker to a pair of positive/negative terminals and you'd connect the other speaker to the remaining pair of positive/negative terminals.

You need to confirm that you have a good signal feeding the amp. If you have another amp in the vehicle, swap the RCA cables between the amps to see if it makes a difference.

You also need to confirm that the speaker are working properly and that there are no broken connections in the wires. If you disconnect the speaker wires from the amp and touch the wires across a D-cell battery (for a fraction of a second), the speaker should pop. if it doesn't, check the wiring to determine why.

you have a foulty amp i wtake it bk and change it

Hifonics Brutus... | Answered on Dec 27, 2007


make sure your power and ground wires are 4 gauge thats a big power puller also make sure your wires to woofers are correct!and you want a short ground wire and a good spot for it no paint!!
if there out of phase that will shut it off BUT you might be needing a battery cap. MORE POWER!!!!they dont cost much
and save your battery and alt.hifonics is a good choice my favorite are the series 7 they dont make them like that anymore!
hope this helps one more thing your alt.how many amps is it?
my honda is only 60 amps your brutus pulls that all day !
(BATT.CAP.or HAVE ALT.WRAPED for more power.

disconect all power cables then short between terminals G&P G&R .a little spark but ok.try after 10min.

Your amp could still have a short not allowing it to provide audio to your speakers. Confirm that your speakers are not blown. Use VOM meter to confirm the ohm rating.

This means that the remote wire is 0V instead of 12V. Try to connect it over from the 12V to check if it powers on.

MKe sure you have 12 vole coming from m your remote will re after your system starts up.

By your description allegedly 2 x 100watt. So 200w music power.

Run a dual 2ohm sub on it. Bridged parallel. That will give you your max. 600rms/1200max
