I have recently purchased 2 10" Kicker Comp 8-ohm subs for the simple reason that I already had an amp that matched the power rating for the subs at a 4-ohm load (amps rating). The amp will put out about 800w @ 2-ohm and 400w @ 4-ohm load (rms values). By running 2 single voice coil 8-ohm subs wired in parallel you are effectively cutting the impedance in half (8 + 8 = 4-ohm in parallel). To do this you simply connect the positive terminal of one sub to the positive of the other sub and then to the positive of the speaker output on the amp. Same with the negatives, sub to sub then to amp. Had I purchased the more common 4-ohm single voice coil subs my load to the amp would have been 2-ohms and too much power would be getting to the subs (100 watts more rms power than the peak power the subs could handle). I did this because of the space I had available and also because the Kicker Comp has performed well for me in the past as an entry-level woofer.
Hope this helps!
you ohm load is too low. raise the ohm load or buy an amp that is stable at the ohm level of the sub.
no the higher the ohm the more resistance in the speaker the lower the resistance the more power it will use so if they are the same make the 4 ohm should be louder
The sound quality won't be very good
A Kicker cvr 10 or 12 inch DVC 4 ohm sub
if you put 2, 8 ohm speakers together on the same channel you will trick the amp into seeing a 4 ohm load, it is not advisable to run a 8 ohm coiled speaker on a 4 ohm amp unless you do the above. So if you want to run 2 8 ohm speakers from a 4 ohm amp this will work the best although the amp will need to be hefty as its worse to underpower a sub than overpower it! I have used a 8 ohm speaker myself on a car amp and had no problems but it was not a cheap entry level amp! some amps will take it, others will get hot and enter protection mode. Hope this helps!!!
It is the impedence (coil resistence)normally sub component (drivers)are in 8 ohms impedence.2 in parralel is 4 ohms and 4 in parralel makes it 2 ohms.
Your SUV comes with a 8" subwoofer from the factory. Most likely a 4-ohm sub. I know the Kicker Comp VT 8" will bolt right in and you can get them either 2-ohm or 4-ohm. You would probably notice quite a difference putting a 2-ohm in.
Hook all the negatives together, and hook all the positives together. you would have 2 wires for each. one from the amp to the first sub, and another going from the first sub to the second.
4 Ohm subs wired in series gives an impedance of 8 Ohms. 2 4 Ohm subs wired in series, wired with an 8 Ohm sub in parallel gives you a final impedance of 4 Ohms. Speakers wired in series raise impedance, speakers wired in parallel lower impedance.
With system you mean the output impedance of an amplifier. No Problem to do this, but there are really no amplifiers with an output impedance of 8 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
in parallel No. Two 8 ohm 'speakers in parallel present a 4 ohm load.
If you are trying to pump a 2.4 ohm sub with a 2 ohm rated amplifier you should be fine. The rating on the amplifier is the least resistance it should have on its load. Anything less than 2 ohms would fry your amp.
