Need help on wiring...

[drockstar 10+ year member]

I want to run (3) 6.5" and (2) 1" tweets in each door, all 4 ohm. I also want to run a pair of 3" in the dash. No passive x-overs. I have (2) 4-channel amps, one of which will run 4 tweets and 4 - 6.5". My question is how can I use two-channels from the second amp to run the third set of 4-ohm 6.5s while matched to the 4 6.5s on the first amp running at 2-ohm? The other two channels would be dedicated to the 3"s in the dash.

The amps are identical.

I think what you'd have to do is bridge 2 channels of the second amp to run the 3rd set of 6.5s in parallel, final impedance of 2 ohms.

That would put them in mono, but may be an option. Hmmmm.

You would use 2 channels to run the 6.5’s @4 and 2 channels on the 3.5’s. Let's say your amps are 100x4@4 200x4 @2..... each 6.5 would be seeing 100 watts, each tweeter 100 watts, and the 3.5’s 100@4 watts.... or am I missing something?

Yea I thought of that but it's not an even double with my amps. They are 240 watts @ 2 ohm but 160 @ 4 ohm. So I'd have two 6.5" on 120 watts and the other at 160.

Just gain match them, use a dmm to set the amps so your getting the same power to each at full volume.

Why you running so many speakers.

Why you running so many speakers.

To keep up with 4 12"

^^ I don't understand, what do you mean by that? your speakers not loud enough?

Have you thought about using 1 amp per side and then add a 2 channel amp for the 3.5s?

No and I think this is a great idea.

just do it like garychoffman said. dont know why you would want or need to do it a different way unless you are going for sq but with 4 12's I doubt that is the case.
