3 subs to KFC-9102d

[kengokusuri]

I recently purchased a single 12" type R(2) and a kenwood excelon KFC-9102d mono block amp. I have 2 10" kenwood blue typhoons in a sealed box lying around and was wondering about throwing them in the trunk with this type R, my current amp is pathetic and with 850 RMS at 2 ohms I could push all 3 subs easily. Wondering if the amp will be stable? And if so, how should I wire it? And how do I assure that the kenwoods are getting 175 each as opposed to the 500 I want to run the type R on?

I WOULD RECOMMENDED AGAINST THIS! Sorry to be so critical but here are your problems. 1.) Wiring three speakers is going to land you with a strange ohm load and Kenwood amps, are notorious for overheating at low impedance. 2.) The sound waves produced by 12" and 10" are somewhat different and it generally takes alot of equipment and experience professionals to make it sound good. (this I have never actually attempted before just heard about it). 3.) The amount of power you have available is only stable for the type R, and nothing else. You will be under powering every subwoofer (which isnt bad for them or anything, but...) because you cannot give one subwoofer more power than the others, they will all get the same power unless it is multichannel with separate gains on the amplifier. The type R also has a lower sensitivity than the kenwoods and thus will more than likely require more power to produce the same sound and volume. All is all, I think that if you attempt this you will spend hours and hours in trouble shooting to get what your looking for, I would just run the 1 Type R they are pretty good speakers

the typhoons are between 75-150 rms each and the R is 600. Would that really be underpowering them? Especially with a D class?
