jlaudio16 Posted February 11, 2010 Report Share Posted February 11, 2010 i heard that if you hook up a sub at 2.66 ohm to a 2 ohm amplifier, u will wreck the amplifier is this true? Quote Link to comment Share on other sites More sharing options...
STEvil Posted February 11, 2010 Report Share Posted February 11, 2010 (edited) If it was a 2 channel amplifier and a crappy one, maybe. If your ohm load is greater than the lowest rated ohm load of the amplifier then in general you are safe for monoblock amplifiers. For bridged stereo amplifiers you need to double the ohm load (4 ohm single coil appears as 2 ohm single coil to a bridged stereo amp). There's a bit of leeway though due to impedance rise (box type, coil temperature, number of coils, average coil movement, frequency.. etc).

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

jlaudio16 Posted February 11, 2010 Author Report Share Posted February 11, 2010 yaya im hooking up 3 dual 4ohm subs and i checked on rockford fosgate's website and it says 2.66 ohms so ya i guess its safe then thanx Quote Link to comment Share on other sites More sharing options...
IH8PunkRok Posted February 11, 2010 Report Share Posted February 11, 2010 not even close. if it was less than the minimum impedence probablybut in this case no not at all Quote -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
ISO Posted February 11, 2010 Report Share Posted February 11, 2010 (edited) i heard that if you hook up a sub at 2.66 ohm to a 2 ohm amplifier, u will wreck the amplifieris this true? No! Lack of voltage and increase of current equalling excesive heat build up will damage an amp but if you are running above the recommended ohm load it is always a good thing as far as how stable the amp will run. Had to change voltage and current. Sorry. Edited February 11, 2010 by ISO Quote Isobaric - Refers to the practice of coupling two drivers together to make them act as one.
