will this cause a fire

I have an opportunity to get an ampeg b2r for a good price the wattage is kind of lower than I would want @ 8 ohms 200w @ 4ohms 375w
I own a trace 1x15 8 0hm rated for up to 500w Is there a way to run this amp up to the 375 through my single cab w/out harming either the head or the cab? by the way not to bright so easier solutions are appreciated.

If your question is whether the amplifier can be made to deliver its 4 Ohm rated power into an 8 Ohm load, the answer is no.

Getting another 8 ohm cab is the easiest solution.

You could either get another 8 ohm cab, or replace the 15" speaker in your cab with a 4 Ohm speaker.

I'd personally get another cab. Doesn't matter what kind (2 x 10, 1x15, whatever you want) as long as it's 8 ohms and rated roughly the same as the TE 1x15.

The 200W amp will work fine with your 500W speaker, just the way they are. That's not a mismatch even though the numbers might give that impression.

I think your post asking about getting the 375W out of the head is leading folks to believe you are seeking more volume. If you really do want more volume then everybody's right, adding a second 8 ohm cab would be the best way to go;

No, and there's no reason why you should want or need to. You're assuming that watts and sound output levels are directly related. They aren't. A week or two spent sifting through the FAQs will reveal why.

When are people going to stop saying this. Replacing a speaker with any other is a crapshoot at best. A speaker and it's box have to work together to achieve a good result.

The difference in perceived volume before and after will be very little.

No.

Even if you could, it wouldnt be a huge difference in actual volume (ie barely noticable)

Sounds like a pretty nice amp/cab already. I would leave it alone too.

[chrism2sych]

for me it's about the headroom my band is pretty loud and even running my trace 300w combo w, the extra cab a trace 15" I have to WORK to come through at the proper volume, we for some reason practice cranked all the way up even though our shows are quite a bit quieter. anyway long story short after playing 40 songs having to WORK like that my hand is always in a lot of pain, even though at regular volume I could play through fine. The combo is becoming a less viable option because of the weight to lug the thing around all the time.

The headroom gain will be imperceptible. Reading the FAQs you will discover why wattage is moot, what matters is speaker sensitivity, response and displacement. As for playing too loud at rehearsal, the cause is usually a room that's too small (read about boundary effects and room cancellations in the FAQ also), the cure the knobs on your amps marked 'volume'.

Sounds like you have a band management problem instead of a gear problem...

If you practice at the level you're going to be performing at (or lower), you'll be able to make better music at the gig. If you're playing 40 songs and long rehearsals at that volume too, it's gonna eat away at your hearing too. I'd say keep what you've got for gear, save your hands, save your ears, and make the band behave like pros in the rehearsal.

chrism2sych, it sounds like you need to reherse the band at a lower volume or look for a more powerfull rig. Something like 500+ watts and multi cabs. If not I think your hand is going to fall off..LOL. There are a lot of Neo cabs and lightweight heads on the market now. But I think playing at a lower volume is a better idea at the end of the day.
