OHM Loads

[Heath]

I have a question on OHM loads and the ability of an amplifier to drive them. What would be the ohm load in the following situation on a (2) channel amplifier. Two sets of JL Marine 6.5" (4 ohm) coaxials and two sets of JL Marine (4ohm) 1" tweeters. Essentially each channel would be driving two coaxals and two tweeters. I know that with just the two sets of 6.5" the ohm load would be 2 but the question centers around the addition of the tweeters. Would the tweeters really add that much strain to the amp and if not does the drop in load with their addition really effect the amps performacne.

I know that most would say just go to a four channel amp and be done but I am limited in the wiring setup and rewiring to acomplish this would be a task.

If it is possible to drive this set up with a two channel what amp would be receommended. I am looking at an Audision 2.250.

All comments welcomed and appreciated.

So 4 tweets and 4 6.5s?

It would be 4 single 4 ohms on each channel, I believe that would make amp see 2 ohm load on each channel.

So whatever that amp puts out per channel at 2ohm will be split evenly between the 4 speakers.

I believe

If your using a JL marine component set (recommended), (mid + tweet) you are most likely going to have a passive crossover, your amp will be seeing a 4ohm load.

like above, if it comes with a passive crossover the final load per set (mid and tweet) should be 4ohm, so running 2 sets per channel (2 tweet, 2 mid per amp channel) would be a final load of 2ohm.

if there is no crossover and you are splitting the signal somehow then you could achive a final load of 4ohm per channel [(4 + 4 = 2, 4 + 4 =2)] then (2 + 2 = 4).
