What Ohm Load Will This speaker Combo Produce?

[bones justice 10+ year member]

i jus bought some 18 sound 6.5" midbass speakers and a pair of beyma bullet tweeters.

the tweeters are 4ohm

the midbass speakers are 8 ohm

can i run a speaker and tweeter to a channel on my rockford punch 450.4

if so what ohm load will that produce 4ohm , 2ohm?

also can i run the speakers and tweeters together or should i buy a passive crossover to have it like components.

HELP PLZ.......

It would produce a 6 ohm load, but why would you want to run the amp bridged? Why not just run each speaker to it's own channel.

^^agreed best bet would be to run each speaker to a seperate channel of the amp

18sound takes lots of power...so i guess thats the reason why he may want to bridge.....if u bridging them bones justice....run some condensers on the bullets so that the amp wont read it as a load.....

Your tweeters and mids are playing different frequencies, it won't cause a problem.

To do it right, you need to have a passive crossover splitting the signals to the tweeter and mid. If not you'll fry your tweeter.

Oh, and for those saying an 8 ohm speaker with a 4 ohm speaker ran in parallel is 6 ohms... ummmmm, no....

It's 2.67 ohms.

Yep, it's 2 and 2 thirds ohms.

1/8 + 1/4 = 1/x

x = 2.66667

you need a passive cross over.

but you can run each set on 2 chanell of your amp.

or you can use your mid's on bridge mode.

and use the tweeters on 2 chanel seperatly.
