Alrights heres the deal. I had a 5 channel crossfire amp that was stolen. The place I got the amp from did not have anymore 5 channels, so they gave me a 4 channel and a 2 channel yesterday. So far I would rather have a 5 channel again.

The 2 channel amp is VR202 and the 4 channel amp is VR354. My 5 channel amp was a VR705.

I was told that the 4 channel and the 2 channel together will produce more wattage but I think that the 5 channel I had hit harder. So what I am wondering is what would be better, a 2 channel and a 4 channel, or just a 5 channel amp.

 

Can you post the specs for each amp?

 

VR 202
Bridgeable 2 channel amplifier, 50 W x 2 RMS, 200 watt max., Switchable 6 dB boost at 45 Hz, Input sensitivity selector switch, Variable highpass/lowpass crossover from 50-500 Hz, Nickel plated connectors, 5-way protection circuit, 2 ohm stable 9.3"W x 2.1"H x 10.5"L.

VR 354
Bridgeable 4 channel amplifier, 35 W x 4 RMS, 280 watt max., Independent front & rear variable highpass/lowpass crossover from 50-500 Hz, 2/4 Input switch, Input sensitivity selector switch, Mosfet power supply, Nickel plated connectors, 5-way protection circuits, 2 ohm stable. 9.3"W x 2.1"H x 10.5"L.

(These two I have hooked up together right now)

VR 705D
Bridgeable 5 channel amplifier, 50W x 4 RMS with 300W x 1 class D sub channel, 700W Max, Variable crossovers: 50-250 Hz highpass for front & rear & 50-150 Hz lowpass for subwoofer, Nickel plated RCA inputs for all channels, 2/4 CH switch, Internal/external sub input switch. All channels 2 ohm stable, CFR-3 subwoofer level control, 5-way protection circuit, Mosfet power supply 9.3"W x 2.1"H x 19"L

 

Well, yea. It looks like a the 705D is a much beefier amp. Another drawback of using 2 amps is that you have to mount two amps and wire them separately.

 

well the place i got them from did all the wiring and mounting for free. So its no work for me. So you think that the 5 channel would be a better amp as opposed to the 2 channel and the 4 channel?

 

I have a vr 404 in my car and it looks more comparable to that 5 channel then that 4 channel vr354 does. The specs look a bit wierd. The say that 200 is max on the vr202 but that looks more in line with an rms rating from a 50x2 amp. The 705d can go down to 2 ohms on the sub but the vr202 is only able to go down to 4 ohms bridged. What speakers do you have and how are they wired? The difference between 200 and 300 in reality wouldnt be a whole heck of a lot. If they are running your subs at 8 ohms on the 2 channel but were runing them at 2 ohms on the 5 channel then you would probalby hear a difference. The 202 would be putting out ~ 100 to 150 watts total while the 5 channel would be putting out 300. Then the difference might start to be noticable.

 

you should've gotten VR404 + VR300D as equal replacement for the same power in two heatsinks

 

I have 2 12" audiobahn AW1200Q. I believe that the subs are rated at 800 watts rms each. Thanks

 

Do you know how they are wired or have a picture of the wiring? Its odd that you have dual 4 ohms when the 5 channel would put out the most power with 2 ohms. Your options with dual 4's would be 16 ohms, 4 ohms or 1 ohm. With a dual 2 it would be 8 ohms, 2 ohms or 1 ohm. It seems to me a dual 2 would have been better for the 5 channel but the dual 4s would work better with your current setup. Maybe the gains were up higher on the other amp or the bass boost was on? Thats my best guess.

here are some examples

Well when I went to pick up my five channel and have the store wire it they did not have a 5 channel so they automatically hooked the 2 other amps up and they told me it was my choice between the 5 channel or the 4 channel and the 2 channel. They told me that the 4 channel and the 2 channel together are better than the 5 channel. So about an hour ago I told them I want the 5 channel back.

Good choice?

Thanks
