I have 2 8ohm 10" speakers an 2 4 ohm how can i wire them

I would assume that the 18" was a 4 ohm if the two 10" were 8 each. Though it might work in a pinch, the crossover point would be different and the balance between the speakers would probably be different as well.

you could add 3 more 8 ohm speakers in series / parallel wiring and keep an 8 ohm load to the amp, or
2x 4 ohm speakers in series, or
2x 16 ohm speakers in parallel

What kind of problem are you having with this, I assume impedance matching. 2 speakers in parallel cut impedance in half. ex. 2 x 8ohm in parallel equal 4 ohm. IF the same speakers are in series, they double impedance, ex. 2 x 8ohm in series equal 16 ohm. Now matching 2sp and 2 sp, both pairs SHOULD be wired the same and the removal of 2 (dep on config) usually would be treated as 1 ?ohm circuit that equal the other ?ohm circuit. AFTER the removal of 1 leg, the impedance could double or half, depending on configuration.

Hello , I will be glad to help you.As far as your speakers..It depends on what impedance your subs are rated and if your Picasso amp can be bridged at 4ohm or 8ohm. If your subs are 8ohm each you can wire your subs in parallel and wire them to picasso amp in bridged mode. If your subs are 4ohm each.Then wire the subs in series then wire them to amp in bridged mode..caution do not wire subs in parallel if they are 4ohm .This would bring impedance to about 2 ohms and would be harsh for amp to handle...Goodluck

The easiest way to wire this would be to make sure you have a 2 ohm amp, wire both voice coils in parallel to the amp. This means to connect both + terminals on the speaker to the + speaker output on the amp, then wire both - terminals on the speaker to the - speaker terminal on the amp. With the voice coils in parallel like this it makes it into a 2 ohm load at the amplifier. If you are running for example a 1000 watt amp at 2 ohms into this speaker it would give each voice coil the equivalent of 500 watts of power at 4 ohms. The other way would be to run the voice coils in series (voice coil 1 - terminal to - speaker terminal on the amp, voice coil 1 + terminal to the voice coil 2- terminal, voice coil 2 + terminal to the +speaker terminal on the amp.) The series wiring would give you a 8ohm speaker load to your amp so you would need a 8 ohm amp.

If the speakers measure zero ohms, then the coil is shot. A speaker will not work if it has zero ohms. Replace the speaker. ALL speakers should read 4ohm, 8ohm or above. Zero means the coil wire is shoted. That there is no continuity.

This is a wrong conection.For 8ohm crossover conect two speakers in serie and one in parallel to one of a previos.Check resistans by multimeter

Hi I am Vortash it sounds like when they expand in the heat the activator coils are clear of the magnets giving a good sound .. but when cold they contract touching the magnets and you get poor vibrating sound ,, ? the problem may be two fold .. spaekers not man enough to take ower from unit .. especially if you have replaced the unit as most cars are only fitted with 10watt 8ohm to 4 ohm speakers as standard , and some of the newer cd players start at 25 watts this will disstort the speakers and they need replacing .. if this is not the case and you only have a low powered system usual culprit is water seeping down windows onto speakers at night from damp or early morning dew .. wet speakers tend to disstort.. hope this helps regards vortash

9 times out of 10 home theater speakers are rated at 8 ohms. However, 4 ohms wont be too much of an issue to a receiver unless you are running 2 sets of 4 ohm speakers and plan to crank it all day. In a simple nut shell, CV! utilizes 8ohm because they are known to build speakers for parties and fun times. It wouldn't hurt to borrow a volt meter and connect it to the speaker terminals to find out. However, you are pretty much good to go.

You will bridge the amp, and if the subs are all 8 ohm subs, you can probably wire them all in parallel, if they are all 4 ohm subs, you would wire then in series.
