I wouldn't see why it couldn't be done, so long as you have enough air space and a thick walled box to house (heavy screws not nails).. plus enough raw power to push them sustainably. If going in a vehicle i would highly recommend dynomatting the tar out of your trunk. maybe around doors as well.
wire two 8 ohm speakers in a parallel circuit!
I presume you mean wired to four ohms amplifier output: In this case, pair the two speakers in in series which will make the give you 18 Ohms and then join the two pairs in parallel which will result in approximately eight ohms. Then connect then in that format to the amplifier. It will work for you.
Use 5.2 ohms, which is the closest to 8 ohms.
No. Two 16 ohm speakers connected together are either 32 ohms, if wired in series, or 8 ohms, if wired in parallel. You can, however, connect four 16 ohm speakers in series-parallel to get 16 ohms, with four times the power handling capacity of just one.
All amplifiers are rated to handle a certain speaker impedance. The majority of loudspeakers have an impedance of 8 ohms while most amplifiers will be able to drive a minimum load of 4 ohms. It is important to check the ratings of the amplifier before adding more speakers. If two 8 ohm speakers are wired in parallel, the total impedance will be 4 ohms. If 3 speakers are wired in parallel then the total impedance will reduce to around 2.5 ohms. If the total speaker impedance is lower than the rated impedance of the amplifier, it is quite possible to damage the amplifier as the output level is increased. To be safe, make sure you understand the impedances of the speakers and the amplifier's rating before hooking anything up.
Two four ohm speakers in parallel is two ohms. Make sure the amp is rated for that load impedance, or you could damage it.
Don't know how you have subs wired but should be 4 ohm load is what your amp will see.
Typical car stereos run speakers at 4 to 8 ohms, so I would wire the two 16 ohm speakers in parallel to get a net 8 ohms. Anything over that would be a little much for a car stereo. You don't need to drive it that hard.
It depends on the application. If you have an amp that is stable in 8 ohms per channel, then 8 ohm speakers will work best. However, if you wanted multiple speakers on that channel you could use two 16 ohm speakers.
Yes, but you should be careful not to exceed the amplifier's mininum impedence rating for each channel. If your amplifier is rated down to 4 ohms, you cannot connect more than two 8-ohm speakers on to each lead. Doing so will damage the amplifier. Connecting two 4-ohm speakers will drop the impedence down to 2 ohms, which is lower than most home amplifiers will tolerate.
That should work fine...matching is not critical. However if you want to be "pure", you could: 1...Insert a 2 ohm resistor in series, but that reduces damping and you may get coil resonances. 2...Install a 2 ohm to 4 ohm transformer. Hard to find and expensive. 3...Install two speakers in series, remembering to phase them correctly.
Two 8 ohm speakers in parallel is 4 ohms, and the power will be split between them. However, unless the amplifier is rated for 4 ohm operation, you will not get the same total power out of the amplifer as you would with an 8 ohm load.
