I just bought a pair of 4ohm speakers to replace a pair of 8ohm speakers. The wires of the original speakers snap in place behind the speakers but the new ones dont. Im trying to fin out how to hook the new ones up.

Re: aftermarket 6 x 9's
What type of car is it? You can purchase speaker harnesses at any car audio shop that will allow you to snap into the factory plugs.
Also, beware if your system was designed for 8 ohm speakers - using 4ohm speakers instead could cause some problems. Most aftermarket stereos are designed for 4ohm speakers, but some factory stereos designed for 8ohms could be damaged if you give them a smaller ohm load.

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 statement on page 7 might allow enough wiggle room for a single pair of 4-ohm speakers used alone. Procede with caution and don't try to blow the walls down with them. Monitor for excessive heat or strain and if it clips or self-protects back off.
The only way to wire a single 4ohm DVC sub to present a 4ohm load is to just connect one voice coil. If you wire the coils in parallel, you get a 2ohm load. If you wire them in series, you get an 8ohm load. But it will work great with just one voice coil. Or if you really want to use both voice coils, and your amp isn't stable at 2ohms, wire the voice coils in series and present an 8ohm load to the amp. It'll work fine, it just won't deliver quite as much power.
Weather of not you can use this speaker as an extension cab depends on a number of things. First, what amp are you planning you use for it? What is the minimum resistance for this amp (2ohm or 4 ohm probably). Second, what is the primary cab you are using ans what is the resistance on that? (2ohm, 4ohm or 8ohm).
Is there just one speaker in you proposed extension cab? The goal is to have all the speakers wired in parallel without lowering the resistance to a point that will damage the head. So if your amps minimum resistance is 4ohm then your cabs will have to both be 8ohm, running in parallel the overall resistance will be 4ohm.
One thing you should know when you install the new speaker it is going to pull most of the power away frrom the factory speaker. In order to get the true sound of the speaker, remove the factory one..I know that the door panel might give you trouble, but it will be worth the trouble..If you tell me what kind of car you are working with, I can help you remove the panel easy.
Yes you can,,,,,BUT the output labelling on the AMP will tell you where you can connect the 4ohms or the 8ohms....please read these labels and connect the 4ohm speakers to the 4ohm terminals, and the 8ohms to the 8ohms terminals...
If you intend to connect the 4ohm and the 8ohm speakers in parallel then the output impedance terminals you use should be the 4ohm ones.
If there is no labelling showing any 4ohm output terminals then its best if you dont use the 4ohm speakers at all....just connect the 8ohm to the 8ohm terminals...you dont mention any crossover networks inside the speaker boxes or if you have tweeter speakers... so just stick to the basics above at present....
I have never heard of this brand of amplifier.. but NEVER hook up unequal ohm loads to a amplifier. the only way i could think to do it would be to hook up 1 of each sub on each side... what way you are spreading out the ohm load equally on both sides
but again if you dont do your math and you run too low of a ohm load you WILL smoke that amp..
