Re: problem with hifonics 1505 class d mono

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.

I have 2 Pioneer TS-W3002D4 12 In and a Hifonics Brutus BRZ1200.1D D-Class Mono Block what's the best wiring

you need to wire each sub down to 2ohms then wire them together like the one in this pic witch will give you 1ohm so you will be getting every bit of power that amp has but you should get a bigger amp for thos speakers

Hi iv just bought one of these and only just fitted it and the protect light is on and i have tried what the manual said but it still comes on and i live in australia and hifonics here dont have service...

G'day, I have dealt with Hifonics a fair bit here here in albury, we used a complete system for a competition car. the amps are pretty solid, but they are very sensitive to wiring. I would start by taking off one set of wires at a time and see if the protect light turns off. (make sure there is no power to the unit when removing or fitting wires) so for instance, start with the front left speaker, then if not move to the front right. etc etc.... By doing this you will be able to narrow down if and where it is shorting out. if you check all your wires and the protect light is still on, i would check where you have mounted the earth cable. make sure it is a solid connection, and that there is good metal to metal contact.
if you have any further problems, or this doesn't solve your problem phone, 0413443600, and i can walk you through further trouble shooting.

Why does the hifonics bxi1608d 1600 watt super D-class mono have 2 postive terminals and two negative terminals? would that cause my speakers to blow?

That is still a single channel cass D amp. Each (-) and each (+) terminal are connected so its actually like only having one. This is so you can hook speakers up in a series circuit to lower impedance, because this amp is 1ohm stable. What causes your speakers to blow is too much power. What kind of speakers are you running? This hifonics amp is very powerful, they are getting big in the competition industries beacuse they put our true power for less money and they are tough. That 1600 amp you have may be putting out more like 1800 watts at 14.4 volts which is 900 per sub at 1ohm so be careful this amp has tons of power and its true rated its not like a sony or rocksford or kenwood that says 1800 max and then in small writing it says 500 rms. This amp puts out true. I have 3 hifonics amps and love them.

When i connect the amp to power it pops.The protection light comes on. The speakers and RCA are disconnected. Do you think the is damaged?

there is a very good chance its shot but, first check the fuses (on the amp) to make sure they are not blown and make sure it is grounded to clean metal.

I have a HiFonics 1206D amp and it keeps blowing the main fuse

The 60A fuse is WAY too small!!

The amplifier's Fuse is 80A
You will want the MINIMUM battery fuse @ 80A as well.

Since the current draw at the battery is greater because of the resistance of the wire - an 80A - 100A fuse is recommended.

The purpose of this fuse is to protect your BATTERY if something happens along the length of power wire.

What kind of "shop" are you using?? I would find another one!

It's likely that the amplifier has shorted output transistors. If that's the case, they will have to be replaced. If you have zero experience with electronic repair, you should pay someone to repair it instead of trying to repair it yourself.

Let me know if you have any other questions.

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.
