Hi again,

It would seem that you posted twice on a related concern. Pls see your other post.

As to your question here, to run two (2) 4 ohms speakers in parallel would require connecting both +s and their -s together. A speaker wire to either leading to the amp would suffice. Alternately, both can have their own wires and meet at the amp's speaker terminals. However, with reference to your other post, if the amp is not rated at 2 ohms, then the possibility of early clipping or the amp being overloaded is there.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Can i run a 4ohm.dvc & a 3ohm.svc off of a mtx te 801d


if you wire the 4 ohm sub voice coils in parallel you will have a 2 ohm load for the Image Dynamics sub, the JL sub only being single voice coil will of course be 3 ohm.
You cannot connect them both to the amp you specified as when connected the total load will be less than 2ohms and the amp will either trip it's protection circuit or could damage the amp, My suggestion is to try each sub separately and decide on the one you like the most or obtain a matching pair for the 4ohm DVC.

I just needed some help with wiring my p8002 rockford amp to 2 fosgate 10 inch subs i just bought. there 4 ohms a piece and dual voice coil. i dont know much about car stereos but people keep telling me...


Well i tried looking up that amp, but Fosgate sight is down. So assuming that the best power out of your amp is 2ohms off the bridged hookup, and the subs are 4 ohms per coil, the best way is to only use one side of each speaker and hook it straight the the bridge. Only using one hook up wont hurt anything, its just for giving you wiring options. And when adding up ohms of speakers, it goes like this. If you had two 4 ohm subs, that'll give you a 2 ohm load. If you hooked up all your hookups, it would be like having four 4 ohm subs, and would give you a 1 ohm load.

Alpine x is not reading proper ohm resistance amps blew


the gmax amps are only 2ohm stable. it is odd that they both blew at the same time but if the impedence is too low to amps will fail.dual 4ohm dvc subs wired in parallel should read around 2ohms. allthought impedence varies with frequency and isnt truly stable.

How do i bridge 2-4ohm dvc's to a mono block


If you have a DVC 4ohm speaker, and you are using both voice coils, the amp is seeing a 2ohm load.
If you bridge the amp, you CAN run both subs as long as the amp is Two Ohms Stable.
Wire each subs voice coils in parallel.(Positive to positve, neg to neg.) (2ohms) each.
Then wire the two subs in series.(Neg from amp to neg of sub one, pos of sub one to neg of sub two. then pos of sub two to pos of amp.

If it sounds too hard, leave it as you are already running the amp at two ohms.

Finding the best amplifier


Hello sharky75,

That 1600 watt peak power figure for your subwoofer can't tell you what amp you need. You need to know the maximum RMS power the sub can handle. And you need to know the impedance (ohms) of the voice coil(s). JBL GT5 series subs have an RMS rating of 275 watts. The GTO series handles 300 watts. The Power series handles 400 watts. The GTi series handles 700 watts. Some are single voice coil, so the impedance is fixed. Others are dual voice coil allowing you to wire them for different impedance loads.

For maximum performance your amp should be able to provide at or near the same number of watts RMS into the lowest impedance at which the sub can be configured. For example, if your sub is the Power Series Model number P1224, it has dual 4ohm voice coils and can be wired to present either a 2ohm load (parallel) or an 8ohm load (series). You want to wire the voice coils in parallel for the 2ohm load and select an amp that outputs up to 400 watts RMS into 2ohms. The Orion Cobalt CO8001 is just such an amp. If you have one of the GTi Series subs, a better amp would be the JVC Arsenal KS-AR75 which outputs 700 watts into 2ohms.

Hope this helps.

SWR-1242D wired at 4ohms


Hi!

Having to much power for a subwoofer is a veeeery good thing, it will provide a lot of control and quality sound to your sub.

But this sub is a dual voice coil at 2 x 4ohm so if you want to hook it up at 4 ohm u need a 2 channel amplifier running mono mode.

i dont recomend that you hook up in 4 ohm, its better to take some time adjusting the levels on the amp and the headunit.

This system has the potential to create a realy good bass sound if u tune it the right way.
