The Best Path to Take

Lars Ulriched · 11-08-2010, 07:09 PM

Posted it in DIYMA but got no proper answer....so I hope Ill get it here....If questions sounds dumb it might be because of my english...so please bear with me....

Which is the best path to go....

my amp is orion XTR 900.2 (900 W RMS Mono at 4 Ohm, 450 W RMS x 2 @ 2 Ohm) and my sub is SI BM MKIII

1) Wired the sub at 8 Ohm and bridge my amp to 4 Ohm which will produce 900 W RMS...but since the sub is wired to 8 Ohm so it will halved the power to 450 W RMS???

2) Wired to the sub to 2 Ohm and the amp to 2 Ohm so it will produce 450 W RMS...and leave the other channel unused....

wire the sub to 8 ohms and give the sub 450 watts. Thats really all your supposed to give a single bm anyways

I'm considering that...but im just not sure if that will work...cos its too technical for me to understand....friends suggest me to wired the sub to 2 Ohm....but use to read ppl says 8 Ohm = SQ....wonder if that just another hoax in car audio...

I would wire your BM mkIII's coils in series to supply your amplifier an 8 Ohm load. When you do, KEEP THE GAIN TURNED DOWN!! Power handling is NOT a power requirement. You don't have to send a BM mkIII 450 watts to get it to perform well. The BM mkIII's are not indestructible so you must exercise caution when putting a lot of power on them. If you wire it down to 2 Ohms and break the subwoofer, don't say we didn't warn you.

Actually the answer was there, just maybe not when you posted. I responded to wire it into an 8 ohm load and enjoy. You'll love it.

My suggestion would be to get 2 and wire them @ 4 ohm

As previously mentionned, please keep the gains down.
