velcroslap Posted December 9, 2009 Report Share Posted December 9, 2009 (edited) Just got mine today and was wondering how much power I should feed into the crossovers. I'm running one amp to feed both the woofers and the tweeters. The woofers are 100rms and the tweeters are 75rms. Now my question is do I feed 100 watts or 175? I assume ohms stay at 4 when using one amp.

iTech Posted December 9, 2009 Report Share Posted December 9, 2009 Are you tryin to feed power to the subs through the T1000BD? Or do you have a 2-Channel or a 4-Channel Quote My Official Feedback Thread PSN - tech2332 Games for PS3: Killzone 2, BattleField: Bad Company 2! Add me to play either!

You can't really control how much power you feed it, except for lowering the gain if the amp is too powerful. How much is your 2 chan. amp rated at 4 ohms?

I'm asking so I can find out what power range the amp needs to be.

Ahh my bad, I understand now. I believe you would need to get a 2-Channel amp that outputs 100 Watts RMS X 2 Channels - (1 for each crossover) @ 4 Ohms. Someone correct me if I'm wrong. Edit: Here's a Rockford Punch that would suit those, Just to give you an idea of the specs.

Then when looking at the crossover it has inputs for the tweeter and woofer, which would mean 100 watts to the woofer and a seperate 75 watts to the tweeter if running two amps. Since I'm only running one amp, I was wondering how a 100 watt channel @ 4ohms can feed a 100 watt woofer and 75 watt tweeter.

iTech Posted December 9, 2009 Report Share Posted December 9, 2009 (edited) The main deciding factor is actually the mid range driver since the coil on the tweeter is so small. It has a small effect on the overall impedance. Since they aren't playing the same frequencies, their impedances don't add together. So I think you'll be fine with what I said.
