Hifonics colossus-ltd dual monoblock amp does not have much output, running a cerwin vega stroker dual 2 ohm sub wired 4 ohm load bridged


Bridge at 4ohms your only getting 600watts rms. You will need to bridge at 1ohm (parallel) and adjust the gain accordingly. This will give it 1600 watts rms. If you would of had a dual 4ohm sub, then you could of bridged it at 2ohms mono, but you can't you have to go either 1 ohm or 4ohm. I believe it's not getting enough power.

When I bridge the BAMF 2200/2 Power Acoustik amp it cuts off


Hello munchisfun,

I'd suspect that the amp is operating into too low of an impedance and going into protection.

The 2200/2 is not rated to drive a 2ohm load when bridged (most 2-channel amps aren't) and when you connect 2 4ohm subs in parallel, the load is 2ohms. I'd run one sub from each channel.

Hope this helps.

DONT KNOW HOW TO RUN 2 OHMS


Hello storres18,

If you have the Kicker model number 06CVX122, with dual 2ohm voice coils, they can be connected to a mono amp at 2ohms. First jumper the voice coils in series, the dotted positive (+) to the undotted negative (-) (or vice versa). Each sub is now 4ohms. Then wire both of the remaining positives and negatives together on the amp terminals (in parallel). The amp sees a 2ohm load. Here's the diagram:

If you have the Kicker model number 06CVX124 with dual 4ohm voice coils, they cannot be wired to present a 2ohm load. They can only be wired as a 1ohm load (too low for the amp) or as a 4ohm load (at reduced power). Here is the diagram of the 4ohm wiring:

I have 2 kicker l7 12 dual voice coil subs.. i just friend a hifonics 1600w amp and am wondering if a kx 1200.1 kicker amp will be enough to power them they are 750w rms a piece .. can these be run at 1...


it all depends on the impendance of your subs if u have duel 4ohm or duel 2ohm, 2 duel 4ohm speakers can be wired at 1ohm to the amp, and with a kx1200.1 that would be pushin 2400 peak and 1200rms
if ya have 2 duel 2ohm speaker than you can only wire them to 2ohm and would be pushing 1200 peak and 600 rms with the kx1200, so if you have the duel 4ohm i would go with the kx1200.1 and if u have the duel 2ohm i would go with the hifoncs

Dual 2 ohm or dual 4 ohm?


I would suggest you go with the 4ohm. It won't be a loud but it will be more stable. You will be less likely to blow up your amp with the 4ohm.

Help???


It's not really made to run a dual 2ohm sub. What you can do though is wire the sub like this:

we'll call you subs voice coil A and B. Wire it like this A's(+) to (+) on amp; then A's (-) to B's (+), then B's (-) to (-) on the amp. This is known as series / parallel wiring it will effectively make your amp see a 4ohm mono load.

What brand and model of amp do you have?

Wiring my kicker solo-baric 15's


The best you can do is connect the dual 2 ohm voice coils of each respective sub in series (4 ohms total per sub) and then connect each sub to one channel of the amp. This will give each sub 1000W, which is the rated maximum from Kicker.
