Tapco Juice 1400 or Samson SX 1200?

[splatee]

I am trying to decide between these two amps and would like to know if anyone has used either of them? Tapco Juice 1400 and Samson SX-1200. I will be powering some dual 4 ohm subs that I will be running at 8ohms each per channel and are rated around 300 to 400 watts rms.

Thank you

Why run a 4ohm sub in 8ohms?

If I am reading the OP right, they are DVC which means you can either run stereo 8 ohm or stereo 2 ohm.

Most of the pro amps can handle 2 ohm stereo but it's not recommended to reduce the fan CFM when operated at that load.

Yes they are dual 4 ohm voice coils. I am going to run them at 8 ohm. Both of the amps are close to each other in power at 8 ohms. I am just looking for anyone who has had either amp to give me their opinion.

Thank you

Why not bridge one amp and run each speakers' voice coils in series, then connect the drivers in parallel? That way, the load it 4 Ohms and the amp is happy, plus the amp is bridged, which gives you a ton of power. That would mean your amp would be putting out more power than you'll need and you can decrease the input sensitivity, which increases your headroom.

So it wouldn't be reccomended to run the amp at 2ohms? Or it's not reccomended to mod the fans to make it quieter and run it at 2ohms? I was thinking about running at 2 ohms. I don't want to wire up the subs to a 4 ohm load and bridge the amp, less wiring to do.

Thank you

Ok just got the Tapco Juice 1400. Now i have a question. Does it matter what type of connection from the receiver to the amp i use? I am going from the sub pre-out. Do i just use a RCA to XLR adapter or use a RCA to 1/4" TSR adapter? Does it make a difference? And how do i set the gains? The sub level out output.

Thank you

Whether it can run at 2 Ohms depends on the design and modding the fan to be quieter won't let it cool better unless the mod is to install a quieter fan that moves the same amount of air.

You need to find out what is required for bridging and how amps operate. "I don't want to wire up the subs to a 4 ohm load and bridge the amp, less wiring to do." is no more wiring than running in stereo- it's just that all of the wires would then go to the terminals marked for bridged operation, the correct input jack is used and maybe a switch would be moved to a different position. If you already have speaker wires run to the amp's position, this is all that's needed. Most amps aren't perfect voltage amplifiers, which means that halving the impedance won't double the voltage. Often, you'll see about 60% more power at 4 Ohms vs 8 Ohms or 2 Ohms vs 4 Ohms. DO NOT BRIDGE THE AMP INTO A 2 OHM LOAD UNLESS THE MANUAL SPECIFICALLY STATES THAT IT"S ACCEPTABLE!.
