I've got a 5 channel amp that I want to hook up to a
10" Sub, and the doors or the mid-bass drivers I have in the sails.

Sub: 150W RMS 4ohm DVC
Doors: 90W RMS 4ohm
Sails: 200W RMS 3ohm

Here's my choices with the amp:
#1 4ohm: 50W x 4 + 200 x 1
#2 2ohm: 100W x 4 + 400 x 1
#3 4ohm Mono Power: 200W x 2 + 400 x 1
Peak Power: 1400W

What's the best combo?

#1 since it is impossible to do the other 2.
#2 requires 2 ohm speakers, you have 3 and 4 ohm speakers
#3 requres 8 ohm or 2 ohm speakers, again, you have 3 and 4 ohm speakers

but with number one you should be able to get 50W x 4 (probably a bit more to the sails since they are 3ohm) and wire the sub up as 2ohm and you should still get 400W to it (maybe it can take a bit more than 200W, you just have to play around with it)

I can't do #2?

#1 & #3 I would wire the sub and the the mids in series. (not together)

for #3 the rating on the sub channel is 400 x 1 at 2ohms right? I wouldn't recommend wiring the sail panel speaker and subwoofer together. The 10" sub will be able to play a lot lower than the 6.5" sail panel speakers, hooking them up together means both will play the same frequencies unless you plan on putting some type of filter before the sail panels. I would just do number one, 50W should be good enough for the fronts and sail panels, and then make the subwoofer handle the bass.

I want to add the 3ohm SVC subs I have in the sail panels.
Like this


The manual says the amp is bridgeable but nothing about "Tri-Mode"
Is this a good idea?

running the 3ohm SVC subs in series would give you 6ohm plus the 4ohm DVC sub would give you 2ohm. 6ohm and 2ohm in parallel gives you 1.5ohm. Not sure if you want to run that channel at 1.5ohm. The amp might be able to handle it but you risk blowing it if you run the gain too high.
Plus, usually when you bridge two channels then you need to use a 4ohm load.

The 10" is wired is series.
I thought that adding other speakers increases ohms.

4ohm DVC in series = 8ohm
3ohm SVC*2 in series = 6ohm
14ohm total?

These would all be on the same channel. (see post #1 for amp specs)
The amp is 2ohm stereo and 4ohm mono stable.

you don't add resistances that are in parallel
(R1*R2)/(R1+R2)=8*6/(8+6)=3.43ohm
That should be fine to use on a bridged output

I see, this is a combination of series/parallel.
thanks
