Bridging hifonics vii

I have an old skool hifonics zeus vii amp. First is this amp bridgeable and if so, how do I bridge it? I have six 12" speakers that I want to hook up to this amp. If its not any trouble add a diagram. Thanks.

Find the minimum impedance supported by your amp so you dont burn it up.

SOURCE: bridge a not bridgeable amp

It will probably blow a fuse or blow up completely.
When the output stages ar not lifted from ground
as is the case in a bridgeable amp bridging cannot
be done.

SOURCE: kenwood kac9152d bridge mono wiring diagram

I have owned this amp for 2 years and i have it up to my kicker L5 sub, in a 3.1 cubic foot ported and chambered box that is tuned to 33hz. the amp can be wiried for eitherrunning one sub or several subs, rms power is 500 watt @ 4ohm, 900 watt @ 2ohm, and 1600 @ 1ohm. it is a strong amp, and it puts out large and powerfull amounts of energy, the bass remote is an added touch, i had it set to 100hz on the amp at +1 on the input sensativity, i ran my sub hard producing 138.40 db on a term lab. and i only had the remote at +9/+11 for level and set to 43hz on frequency boost, if you have only one sub with single 4ohm voice coil run it on the outer sides of the speaker outputs on the amp, if you have a dual or quad voice coil, you can either lower the ohms wiring the sub in a paralelle circuit, or up the ohms by wiring the sub in a series circuit. if you have 2 or more subs, wire them left and right channel, the amp has 2 out puts because it is a dual monular amplifier, meaning you can link 2 or more amps together to wire one or multiple subs, witch makes this amp perfect if you have a 180db, @ 18hz **** , than this amp is for you!!!!!! if you need more advise on the amp or how much power it needs to run it or when the amp loads into protection mode feel free to email me @ zekk68@hotmail.com

you need an noise filter in line. It's been a few years since I've had a system but I had the same problem. High power amps like the one you have can actually pick up on the electric pulses from your ignition system. I think I got mine at walmart, or auto zone, somewhere like that. Their pretty cheap too. I don't remember how its hooked up, but If you know how to hook and amp up, this should be no problem.

SOURCE: can i bridge this hifonics amp

If you don't know if the amp is bridgeable, then I wouldnt do it. It could already be bridged internally and bridgeing it through the speaker terminals could be disatrous, i.e. the infamous blue smoke of death. The amp looks like a 2 channel amp fromt he pic and you have two speakers you are trying to power with it. So the safest bet would be to just unbridge your speakers and hook them each up to the amp as normal. No blue smoke. Good luck!

I bridged my lavzar vector 6000 watt amp to 2 12"


Could be a thermal protection circuit. If your subs are 4 ohm speakers and they are in parallel, then your amp is seeing 1 ohm, which probably puts out a lot of power but the impedance may be so low that your amp is overheating. Usually, after a thermal protection, it will come back on after it cools down, but that can take a while, especially depending on ventilation.

Keep in mind that when you bridge an amp, it's "seeing" half the impedance. Two 4-ohm speakers in parallel give a 2-ohm load, so an amp bridged to a 2-ohm load is seeing 1 ohm. Dangerously low for most amps unless it's designed for it.

Amp comes on running 2 12" 450 watt pioneer subs, volume only seems to be about half output, with speakers bridged


This could be the reason. If you look at the specs for this amp you will see that the continuous power out is rated for 380W bridged. The speakers rated at 450W should be able to handle close to 315W continuous. Now if you split these numbers being you have bridged these speakers, you drive each one up to about 190W continuous. The speakers are being driven approximately by 60% of the rated capability. I personally like to keep it right where you got it, not exceeding 80% of the speakers rated capacity.

Here are the specs for the AMP:
  • Specifications
  • Peak Music Power 760 Watts
  • Number of Channels 2
  • Load Impedance Capability 2~8 Ohm (Stereo), 4~8 Ohm (Bridged)
  • Continuous Power (4 ohm) 125W x 2
  • Continuous Power (2 ohm) 190W x 2
  • Continuous Power Bridged (4 ohm) 380W x 1
  • Frequency Response 10Hz ~ 50kHz
  • Total Harmonic Distortion 0.008%
  • Signal-to-Noise Ratio 100dB
  • Dimensions 12" x 2-3/8" x 12-3/4"
  • Features
  • Bridgeable
  • Channel # Capability 1/2/3
  • PWM Regulated MOSFET Power Supply
  • Screw-Type Speaker Terminals
  • Balanced Isolator Input Circuit
  • RCA Inputs 2 Channel
  • Input Level Control Hi-Volt (200mV ~ 6.5v)
  • Built-in Crossover Selectable LPF (80Hz, -12dB/Oct.)

    I have 2 12'' subs 1300.watts and 2 1200watts amps both bridge to push 2400.00watts do not sound lond enoungh


    impedance mismatch cud be the culprit. make sure ur speakers are the right ohms for ur amp. most amps are designed to operate on a 4 ohms speaker load on bridge mode. some amps are never designed for bridge mode. so if u bridge these amps u will get less output. u have to be very careful when u make the connections. plus when u bridge two amps for 4 ohms load, the total impedance becomes 8 ohms. make sure ur speakers are 8 ohms. few ohms can make big difference on power amps.

    I have 3 hifonics zeus Size: 12 inch Impedance: Single 4 Ohms Peak Power Handling: 800 watts RMS Power Handling: 400 watts Sensitivity: 89.9 dB Aluminum Cast Basket American Spider For Reliable Performance...


    Hello king3132,

    Three 4 ohm subs can be wired parallel for a 1.34 ohm final load or series for a 12 ohm load. If you have the channels of the amp bridged, I hope that the subs are connected in series because the Sony XM-2200GTX is NOT rated for or stable at 1.34 ohms. It's only stable down to 4 ohms.

    You definitely will not get the maximum potential of the subs from that amp. They can handle 400 watts RMS each (total 1,200 watts) and the amp is only capable of 500 watts RMS into 4 ohms (less at higher impedance), so each sub could only be getting a maximum of 166.6 watts RMS.

    Hope this helps.

    Need help bridging


    First check your gain it may be turned down. I personally dont bridge speakers. I put each speaker to its own channel on the amp.Make sure positive to positive and negative to negative. Try hookin up two speakers to the amp (not bridged) and turn your gain up around half way. Make sure you amp is switch to lowpass not high since most amps have crossovers built in now. The more speakers you have the less output from each speaker from one amp youll get.

    How to


    First of all, make sure your amp is bridgeable. There are a few ways to bridge subs. series: hook one wire from the negative on the left amp output (or whichever is labeled on amp for bridged)to left sub negative. left sub positive to right sub negative, then right sub positive to the amp positive output.(like a big loop through both speakers) parallel: both speakers get their own set of wires, both negatives go to the bridge negative terminal, and both positives go to the positive bridge terminal. Series-parallel: A combination of the two. say two speakers in series, and one hooked up alone, but all to the same amp outputs. Bridging your amp/speakers basically lowers the resistance of the circuit and makes more current flow, more power, louder, harder hit. In series, it also makes both speakers do exactly the same thing, instead of "stereo sound" or L/R differences. What you're probably looking to do is Bridge in parallel. That will drop the resistance of the circuit the lowest, allow the amp to put out the most amount of current to the speakers, and allow your bass to hit the hardest. If your amp only has one output, hook up the same way as above. Just see what resistance your amp is stable down to. If down to 1 ohm, no worries. if stable only to 2 or 4 ohms, you may want to bridge in series to be safe. That will cause the resistance to go up, and will not pull as much current through the amp. The whole time, just remember Bridgeing and higher current mean HEAT so watch your amp. I hope this helped.
