I had started a newbie thread to get some guidance on how I could improve my 'HT woofage' and received tons of valuable feedback.
I have narrowed it down to building 4x subs with 18" SI woofers and Erich's 4 ft flat packs, probably 2 each co-located in the front and rear.
The DIY FAQ thread has great information for a newbie like me. Still in this thread, I am looking for more advice and recommendations for the amplification, as well as the wiring.
What amp should I be looking for?
Cooling fan noise of some of these amps seems to be a common concern. Are there any amps that are quiet or do they all require some sort of fan mod if you have to keep them in the listening area?
I already own a Behringer DCX2496. Can/should I use it or better go with another DSP? If so, one integrated in the amp(s) or as a standalone (miniDSP?)?
I hear that most of these amps do not offer a sleep/power safe mode and are always on. I do not like it and would like to use my AVR to trigger an on/off via 12V. Are there any amps that support this? If not, how do I best go about it? (I saw the threads for building or integrating relays.)
Do I need a separate circuit (or maybe 2) for the amp(s)? Would 25 Amp suffice?
On the drivers: do I need 2 or 4 ohm woofers and how do I best wire up them up (parallel, series)?
What size speaker wiring do I need? I heard 12 gauge throughout will be fine. Is this correct?
Any particular recommendations for binding posts? Anything special I should look for? What advantage to go with speakon connectors?
