Hello, I've been reading up on some of the builds on this site and learning a lot, and so far ive been able to answer all of my questions by searching. Im familliar with simple passive front stages using crossovers and components, but this time I want to try an active 3 way. My question is would this work:
Midbasses: 2 of the focal 6M115 per door
Midranges: 1 Selenium 6W4P per door
Tweeters: 1 Crescendo Supertweeter per door
Now the tricky part, My Headunit has 3 rca outputs, front, rear and sub and ive always been curious as to how people use so many amps/speakers in their setups, and when y-splitters are appropriate.
Here is my thinking:
RCA's
From the front output on the headunit i would connect an rca, then 2 splitters which would go into all channels a 4 channel amp with crossovers i could use for my midRANGES and tweeters
The rear channel I'd use a single rca to connect this 2 channel amp that has an appropriate bandpass filter i could use with my midBASSES
then of course i would use the sub output on my mono amp
Speaker wires
i will use 2 of everyone's favorite selenium 6W4P Midranges, and somehow run the speaker wires to the back where the amps will be, and either connect the 2 together in parralell for 4 ohms on channel 1 (this is what i am worried wont work), or just use each on ch 1&2 separately for 8 ohms each and hope they are loud enough
Same idea with the supertweeters, but i am leaning more toward using channels 3&4 separately, and keeping the impeadence to 8 ohms so they dont sound too bright
for the 4 focal midbasses, i would link each pair in the door together in parralel for 4 ohms, then each back to the 2 channel amp and use the bandpass filter
from there i would use the filters on the amps and see which points work for me
Power, remote, grounds
i would take the existing 0 gau and run it to a distro block that would branch into (1) 0 gauge output and (2) 4 gauge outputs for the 4 and 2 chan. amps
each amp would share a grounding point,
and one further question, is it okay to have one remote lead from the headunit, and simply tap into and solder 2 more leads for the other two amps?
I just wanted to try something different for this build, and before i start some door panels i wanted to make sure this will work. As long as the amps have the right crossovers, i dont see a need for an external active crossover being used (correct me if im wrong) The major things i am worried about are: splitting the front signal from the h.u. so i can use it on my 4 channel amp for midrange and tweets, and wiring certain speakers together for more efficiency.
If anybody has a better, cheaper way of pulling off what i described, please let me know, and i hope its easy to understand what im trying to do. Great site and im sure some of you on here can help me! thanks
