Hifonics bx1500d mono no lights turn on - Hifonics BX1500D Car Audio Amplifier

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.

SOURCE: my Hifonics BX1500d is still going in protection

sorry, i am in the US. I couldnt begin to tell you where to get your amplifier repaired.

Try contacting HiFonics at www.maxxsonics.com


There are 3 possible conditions a HiFonics amplifier will go into protection -

Ground Loop - Blown or damaged speaker causing damaged Output FET.

Power Supply Failure - Blown Capacitors, Damaged FETs, Faulty Relays.

Thermal Shutdown - Excess Heat.

Mono channel amplifiers are the simplest to work on - and I would Estimate a repair cost of $75USD if it is a simple FET replacement.

Look at one hour of labor plus parts.

Hope this helped.
