Good Morning,
Before we get started, I will preface with, I literally spent the entire weekend researching and teaching myself, OHM, Watts, Power, do's & don'ts, RMS, Max Watt (doesn't matter, publicity ploy), and so on and so forth.
The majority of examples only included running series or parallel speakers of the same type, woofers to be exact.
I have a simple question, that I cannot find an answer that explains how/why.
If you wire two sets of speakers, with different RMS, how can I lower power to the lower RMS speaker set?
I have the following RMS for my speaker setup, pending changes that might need to be made.
300rms (8" Sub) - 4 ohms (I also found a dual coil 10" 2 ohms, that can be wired for 4 ohms, with identical stats as the 8)
80rms (three-way component - 6.5", 3", 1",), at 4 ohms.
60rms (two-way component - 6.5", 1"), at 4 ohms.
My worry is with the 60rms 2-way component set.
I found a 4 channel amp, 3x100, 1x300 at 4 ohms or...
1-mono 300x1 and 1-100x2 amps. (in my opinion, 2 amps is a bit ridiculous for such a small 'system')
Another option would be a 2x75 amp at 4 ohms.
From what I have learned, you can multiple the RMS by 1.20 and .90 to find the range of potential amps that will remain in the "safe zone".
80 x 1.20 = 96w
80 x .90 = 72w
60 x 1.20 = 72w
60 x .90 = 54w
The 2x75w amp might be right in the sweet spot for both sets of components.
My other issue is with the lack of Mid's. I assume since both sets would include crossovers, I might be ok?
My other thought would be:
4" knee, 3" dash, 1" dash, 6.5" soundbar - which would require a revamp with amp selection.
I am aiming for better than factory, but cheaper than full Alpine setup. I don't need body rattling bass, but something enjoyable with the top removed.
I appreciate your time and any input. I would like to avoid having a shop charge me out the backside for installation. Plus, I can't find a shop that is open at this time. Since we are locked down, and I work from home, I figured I would work on this during my "home detention".
