tri-mode with 2 2 channel amps *hoping to run 4 speakers one sub*
I have 2 2 channel 100 watts rms each. I am presently running 4 ohms 5 1/4 door alpines and 2 infinity reference 2 ohm 6x9s.
the amps are blaupunkt velocity that says can run in tri-mode. I have 2 altac-lansing passive crossovers I used to run old proton woofer-tweeter compo with.
how can I set up a 8" infinity sub to run in this configuration? If I run an 4 ohm sub with the 2ohm infinity references will that be stable? blaupunkt claims to be stable to 1 ohm.
If I install both passive crossovers to the 2 amps, is there a way to bridge the 2 low bypass signals and run just highs and mids in the fronts and 6x9?
s?
will I loose a lot of volume? I realize running the sub with the 2 fronts would likely be more stable but I don't play the fronts as loud as the fronts.
hope all of this makes sense
cheers

Could you run all your mids in series off one amp (would give you around 6 ohms and lose a little power) and bridge the other amp to your sub?
If you're going to run tri-mode I would run the Alpines and the sub, not the Infinitys. I don't think you can run tri-mode at low impedances. (I iknow you said they're stable to 1 ohm, but that's likely for stereo operation)

If the amps are 1ohm stereo stable, u could run the speakers all paralleled of one 2ch and run the other bridged to the sub. It won't allow tuning of the speakers apart from each other, but u have to run a passive low pass for the sub in a tri-mode setup. These passive coils are a major power consumer. and u should really run a high pass to the components in a tri-mode as well.
Much simpler to run highs off one amp and sub off the other. Everything is crossed over at the amps instead of passively. Except maybe passives for component speakers, if that's what you're running.

It will get you your F/R fade capability and better gain matching. Plus, class D mono amps are SO cheap now, and draw far less current than class A/B amps that your car's electrical will appreciate it. Solid suggestion Dukk.

Do you already have the tri-mode passives though? At the bare minimum you will need a 6 - 8mH inductor and a pair of 200uf capacitors.
Regardless - getting the sub onto its own amp, even if it means running all the other speakers off of the other one amp is the better way to go.
