[QUOTE="alphakenny1, post: 1331006, member: 561605"] hey i have a quick question. just to give a little background i have an 4 ohm DVC IDQ and i was wanting to run an a/b amp to it. so my options are either 2 ohm or 8 ohm. there aren't many amps that are 2 ohm stable bridge unless i want to dish out cash for some expensive amps such as the DLS A2. but i dont want to so i was thinking of hooking it up to 8 ohms and bridging an amp. so my question is if an amp is rated let's say 500 x 1 @ 4 ohms bridged and i hook up the amp to the sub which will be wired at 8 ohms, will i be getting 250 watts? i've seen some specs say like this one for example: [URL="http://cgi.ebay.com/Zed-Audio-designed-Lanzar-Opti-Drive-500-2-No-Reserve_W0QQitemZ5842791016QQcategoryZ18796QQssPageNameZWDVWQQrdZ1QQcmdZViewItem"]http://cgi.ebay.com/Zed-Audio-designed-Lanzar-Opti-Drive-500-2-No-Reserve_W0QQitemZ5842791016QQcategoryZ18796QQssPageNameZWDVWQQrdZ1QQcmdZViewItem[/URL] that @ 4 ohms mono it will put out 750 watts but at 8 ohms mono it will put out 500 watts. i would think that if you double the impedance you cut in half the wattage. any help is appreciated, thx.
