Hey guys,
I play lead for a horror pop-punk band (we sing about horror movies), and I'm building a guitar cab to go along with that theme.

Nothing too fancy.. but what I need help with is this:

I'm going to run 4x12 100 watt 8 ohms speakers.
My head spits out 500 watts at 8 ohms.

I want to put a jason mask, and some machetes (fastened down so it doesn't rattle) in between the speakers, with red LEDs behind them that glow when I'm playing guitar.

I've got the LED part figured out. The leds I'm using each eat up 3.3v and my head spits out 70v peak, so 21 leds in an array, and it'll take the 70v just fine.

Now, here's where my math gets fuzzy, and I don't know what to do...

I was planning on adding my 4 speakers in parallel. When I add the LED array in parallel, I believe it's the equivalent of adding a 5th speaker...

So if I'm doing my math right, the stats of this LED fake-speaker would be:
watts = 1.4 (watts = volts x amps)
ohms = 100 (ohms = volts² / watts)

So What would happen if I added this led fake-speaker (100 ohms at 1.4 watts) parallel with my 4x12 100 watt 8ohm speakers?

I'm sure there'd be a power reduction, but would it really be noticeable?

Bass amps come in a lot high wattages. There are 1000+ watt bass amps.

of course, it would be sane if he said bass, but hes a guitarist.

Lol.. You guys crack me up.

For the head, I'm using a rack mount power amp, behringer ep2500 500 watts per channel at 8 ohms. Only using one channel and using an inline amp modeler for tone.

You're lucky I'm not using 4 ohm speakers.. Then it's be 1250 watts :p

I'm about to get a 600W bass amp, and they make even bigger than that. I say use the 4 ohm speakers it will be epic
#18
I have a bass setup that peaks at 2750W. 500 is nothing.


There will be a noticeable power reduction, but it's still going to be loud as ****. I say go for it.
