I have a pioneer 900 watt amp and im wanting it to push 4, 12" dual voice coils speakers rated at 175rms will it sound decent and will it be sufficient enough to push all four subs

can you be more specific on the amp model and the speakers and what kind of enclosure they are in? if its 900wrms then its more than enough to push the speakers past breaking point. Depending on the thiele small parameters of the subs and their maximum excursion and the enclosure, you could well push them past their maximum excursion at a particular frequency and destroy them with only a couple hundred watts driving them......

Some things to consider: What ohm load is your amp stable at? What is the ohm rating on your speakers? How do you plan on wiring them? If you run them all in parallel, your going to be stressing your amp out big time if it isn't stable at low ohm. If your run them in series you may not notice them working to standards.

Something we do in professional concert audio is wire "Series-Parallel" if you are able to do this with your speakers, you will have a combined ohm load across all 4 subs, exactly the same as there were just 1 (4x4ohm subs ran in series-parallel will have a 4 ohm load).

How that "sounds" all depends on the real power capacity of your amp, not all watts are equal, is your amp rated at 900 watts peak or 900 watts with a THD of 0.002%? If the later is the case (or something similar), your amp will peak much higher than 900 watts. But knowing current technology, and marketing gimmicks , I would bet this is 900 watts max (at 900 watts it will sound highly distorted).

Sure the amp will make the speakers move, it just depends on the amp if it will be able to drive the subs at their RMS rating (or beyond).

Either way, be careful of your ohm load on the amp. Look into how to wire speakers in "Series-Parallel".

Good luck!
