4 ohm?

[Ku-sama]

according to RF's website:

I have two SVC 4 ohm subs.

2 would overload my amp, 8 wouldn't be loud enough.

can I get 4 or should I split the subs onto channel 1 and 2 instead of bridging?

You can't do 4 ohms. Just run them at 8. It's not optimal, but it'll do till you can either get different subs, or a new amp.

I guess I'll just see how my amp likes 2 ohms then....

Go for what you know I guess. 8 ohms is not a horrible thing.

You can still load up at 8ohms and get very close to full power. Amps will yield full power into a variety of loads so don't be affraid to run your amp at a higher load than they say. Your amp will certainly thank you. Going class D, G, H or T is another great idea as well. We know of some great Class H mono bass amps for as little as $120, 940wrms into 1,2 or 4ohm load.

I'm running it at 2 ohm right now without any problems....

Keep an eye on it though. Almost all 4 ohm stable amps will run @ 2 ohms mono for a while. Just be careful.

it is stable at 2 ohm non bridged... besides, if I calculated it right, I'm only using it at half power at 2 ohms anyways

2 ohm non bridged is the same as 4 ohm mono. You're running 2 ohm mono which is equivalent to 1 ohm stereo. There is nothing you could have calculated that will make the amp put out half power @ 2 ohms mono. Turning a gain down will not change anything. As stated earlier, just be careful and keep an eye on it. Touch it to see if it's getting real hot. If the amp owner's manual does not say it is 2 ohm mono stable then it is NOT made to be pushed really hard at that load.

I was going by a DMM.....

gain is not at full tilt.

All that means is your gain is set correctly. It doesn't change the fact that you're showing your amp a 2ohm mono load. If you're careful you probably won't hurt the amp. If you're not you could thermally damage and eventually kill your amp. Just stay cool and it'll be fine.

There was another person on here that had a Lanzar Vibe 286 power 2 P2 D2s and it would shut off after about a month, he was going to buy my amp until I told him what he was doing wrong with wiring, now he's bump really well with them at a 4 ohm load to each channel.

it get's pretty hot, but not hot enough to burn me, just slightly uncomfortable to touch, my kicker gets hotter...

planning on ebaying my 268 for the cash to get either a BXI 1206D or a similar amp...

Some amps just run hotter than others. It all has to do with the heatsink design that makes one amp hotter to the touch. The real question is is the amp ALOT hotter than it was when you were running it at 4 ohms.??
