Q1: Can I use a bridged configuration to power my 3 way component speaker system.
Q2: If yes, do I need to split the front RCAs from the HU using a Y splitter and feed 4 RCAs into the amp? Just curious to know if this will reduce quality of output. My idea is to save some money on my install and not buy a complete set of new amps for my upgrade, since I already have a 4 channel Class D amp.
Q3: I'm planning on the Flux Audio BC 361, which is a 60W RMS 3-way Component Speaker system. Can this speaker no effectively be powered by a single channel (80W) of the Arc Audio amp, rather than even the bridged config? Obviously this would make installation easier and save me some big bucks.
Q4: I am going for a complete audiophile set-up primarily to play blues, jazz, and acoustic music (Eric Clapton and the like). This install will happen in a Scorpio. Will an Infinity Kappa 100.9w (10 inch sub) suffice, or is a 12 inch sub (such as the Rainbow DL-S 12) mandatory? Note that both the Infinity sub and the Rainbow sub mentioned have almost identical power rating |
1. Yes, you can do that, but like you said your speakers have a rated power handling capability of 60 watts RMS per channel, so there is no need to feed them double the amount of required power and then some more.
2. Yes, a Y-splitter will be required if you want to bridge channels and you amp does not have the internal splitting feature(some amps need only two channel inputs to give four channels of output!). I think the gain needs to be set higher if a channel is split!
3. If you mean giving 80 watts to right channel and 80 watts to left channel then Yes, 80 watts is good power to run a speaker set rated at 60 watts, a little headroom is always welcome! Kill questions 1 and 2 if you take this route.
4. While I have never auditioned either of these two subs, I think in an SUV of the size of a Scorpio, a 12 inch sub is what you should look at, they have that little extra thump, kick, bang, zing, zang, whatever you call it, over 10 inchers, which makes them good all rounders.
The Kappa 120.9 is the sub to go for in that price range. The Rainbow DL-S12 is something that's being used by quite a few reputed installers here and there, knowing a few of them I am sure the sub is good, I personally have never auditioned it at all! Any particular reason for wanting a 10 inch sub woofer?
Also, if you're keen on an audiophile set up, I think you should get yourself an active capable HU, if you already don't have one and go active. A passive 3-way set up is hardly alive and I have not come across too many people opting for it.
But, the only way you can go 3-way active+sub is through the Pioneer P99rs, which costs a bomb, or buy a DSP, which again costs nothing less than a bomb. Plus you will need more amplified channels, hence, more amplifiers!
And, if you're keen on audiophile grade SQ, you should definitely get rid of that class D amp, I know class D amps have improved over the years, but they still cant match SQ attributes of class AB amps.
I run a regular 2-way set up (completely self installed!

), so I am not really the one you should trust, just that I am keen on going 2-way active with a pair of widebanders(ditching the tweeters!) and have read up a lot from where ever I could. My gyan on active-passive is limited, gurus can pitch in more info!
PS: I am a cult Scorpio fan, so much so that I made my dad buy one as a 14 year old, but frankly the Scorpio is not an ICE friendly car, poor plastics, weird stock speaker locations, and that joke of a dashboard hardly do any justice to expensive audio equipment!
