just purchased a HiFonics "BRUTUS" Amp.
been sitting here thinking of how to wire it and came up with this layout.



*NOTE: the red wires are both remote bass controls.

as far as the wiring and layout..I think i have a good grasp of it...
If you see something not right then please speak up..

My actual question revolves around this so called Daisy chaining ..

The HiFonics has two RCA female ends on it that say Output.
they claim this amp can Daisy chain .
my understanding is that instead of running 2 preamp outputs to the trunk that i can just run 1 to the HiFonics amp.
Then just run a short RCA jack from the output of the HiFonics to the inputs of the Rockford.

Also, as if i aint typed enough.
I need the rockford to send a full signal to the 6x9's.
The HiFonics is a class D Mono amp.
Will the HiFonics be able to send a full signal to the Rockford?

if you need pics of anything to do with these questions.
amp closeups,specs,anything, just let me know..i have evrythingor can get anything you need to understand my feeble babbling better..

Correct




The inputs on the HiFonics are stereo right? If so, then yes, it will work fine. Although when you daisy chain, you're only using one output off the head unit, sharing whatever voltage it gives out, 2v, 4v...but only 2 daisy chained should be alright, if you had more it would require a line driver to keep the signal strong.

you say the inputs?

i have no clue..
how would it not be?

i just hope that it will send it to the outputs.

I mean, the inputs, use both cables, right?
The outputs on an amplifier are always left untouched, the crossover and such on the hifonics won't affect what gets sent through the RCA outputs for daisy chaining.

see right there you lost me.. i feal so stupid now..

outputs untouched???

the RCA ,that comes from the receiver, i am planning on running straight to the inputs of the HiFonics.

but here is where you confuse me.
on the back of said amp there are OUTPUTS that i was going to hook a seperate RCA jack to and run that to the INPUTS on the rockford amp.

your saying that this is wrong???

on the back of said amp there are OUTPUTS that i was going to hook a seperate RCA jack to and run that to the INPUTS on the rockford amp.

That is correct....what I meant is the crossover on the hifonics, bass boost...whatever it has, will not affect the output signal on it, so essentially, the signal to the RF amp, will basically be directly from the Head Unit, it just gets run through the HiFonics amp...the HiFonics amp takes a little bit of the signal, and the RF amp takes the rest of the signal from the head unit.....

oh shit man i'm sorry..i was thinking something else..my bad...
thx..

i have another question regarding "Project Thumper" that i am currently uploading pics for

The HiFonics amp in question is a 1 channel 1000 Watt Mono amp.
but on this photo of it there are 4 speaker outputs.


the subs i am connecting to this amp are two 4Ohm. dual voice coils.
they are being wired parallel/parallel to acheaive a 1 Ohm. load.
this means that i will only have 1 pos. and 1 neg. wire from the subs going to this amp.

Why are there 4 connections on amp and also which ones should i be using?

never seen a 1 channel amp with 4 speaker outputs.

Hmm...that's weird...
I guess you would use the two outer connections as if it were a 2 channel amp, but it's mono.... :?
Look at the manual when you get it...the manual doesn't appear to be online...

Here:




So you wire each sub up parallel, and connect each sub to the separate terminals, and the amplifier makes the connection parallel!

it is weird..i also seen a HiFonics just like mine that had 8 speaker outputs.

THX again for your continued help..
been alil quite around TOC lately..

another simple yet complex question..
as for the remote turn on deal.
the RCA that comes from receiver has the REM with it which i'll connect to the HiFonic..

do i just run a wire from the same place i put this wire and run the other end to the REM of the Rockford?

that sounds right to me.

also do you realize that the rockford i had powering these subs is giving them 125 Watts each.
i now will have 500 Watts going to each..that just blows my mind right now.

Yep, just connect the remote wire to the hifonics remote terminal, than run a piece of wire off the hifonics remote terminal to the rockford fosgate terminal.

Yep, 500 watts RMS to each sub....loud...boom boom...
As for the quietness...yep...been a bit quiet, everyone must be mourning Reagan's death :?

You apparently have the same alternator that I am going to be upgrading, once my 170 amp alternator gets here. You have the CS-130 105 amp alternator. Do your headlights dim at all with your current setup?

faintly every so often it will..
actually doesn't seem to happen as much now though..

i woory about amp load too..

what are you thinking brando

what I am thinking, is alternator upgrade with that new hifonics 1000 watts coming in, that thing uses a 60 amp fuse, fuses are rated to blow 200% of their current rating, that's a limit of 120 amps....plus the RF amp...

But, first, I would upgrade the wire to the alternator, ground from engine to chassis, and battery negative to chassis to about 4 gauge or more wire.

Then, if that doesn't seem to help, you're most likely in store for a high amp alternator.
