Amp question
Hey guys, I was hoping to post this on sounddomain.com but something is wrong with their forum and I cannot register, so I figured I give it a shot here.
I am working on installing a system in my 04 F150 Scab. I purchased a MTX Audio Thunder8000 dual 4ohm voice coil 10" sub and a MTX Audio Thunder311D mono sub amp. My problem is that I bought this amp planning to run it bridged and wire the sub in parallel to present a 2 ohm load, well I was looking at the amp owners manual last night and it says the following:
Caution: Thunder amplifiers are not recommended for loads below 2 ohms stereo or 4 ohms bridged.
Do I understand this right? I can't bridge it and run 2ohms?? So should I run it in 2 ohms bridged and see what it does, or should I return the amp and get one that is 2ohm stable?
What do you think?
Thanks

Cool, thanks for the reply. I also found this on the MTX site that explains things a little better for me.
How do I bridge a Class-D mono amplifier?
Since we have come out with the Class D line-up of amplifiers, we have had an abundance of technical calls inquiring about how to bridge our amplifiers. It isn’t possible to bridge any Class D amplifiers. All of these models are Mono amplifiers, meaning they only have one channel. You might ask, “why does the amp have two terminals (L and R) if it is a single channel amp?” The answer to that question is: we put both terminals there for your convenience. If you have two speakers, it is hard to attach two speaker leads under one terminal screw. Thus, it makes for a cleaner, easier install. Example: If you had two of the single voice coil 4ohm MTX series 6000 12” subs (model T6124A) and wanted to power it with a Thunder 801D, you could use either terminal. Since it is a Mono amp, as long as the speakers are wired in parallel, it will see a 2ohm load. If you wanted to wire each speaker to a terminal, the amplifier would also see a parallel configuration.
So in a nutshell, I can run at 2ohms in parallel and be cool!
