  1. thanks I thought a 3 way crossover could connect tweeter, woofer, sub instead it connects tweeters, midrange and woofer
  2. Hello, I would like to know how to connect a crossover to the amplifier. there are 2 crossovers that have 2 way and 3 way they have in+ and in- and for tweeters, sub and medium. thanks regards
  3. thanks if instead I have a 3 way crossover where there are tweeters, woofer and sub in this case how do you connect?

    I have identified the two + 12V cables with the DMM now I know which ones are at 8A and at 14 A to power the radio I'm using + 12V 8A are they enough or should I use the 14A one? (at the moment the radio turns on and it works) so you need to connect all the yellow cables and then put a 25A fuse with an AWG8 cable? (since for the radio it is sufficient to use the 8A one) if I connect the yellow cables the power supply to the radio must come from the biggest cable AWG8? the other cables (red, black) I have to connect them together or I leave them free? connecting the various yellow + 12V cables I would not have the sum of currents above 22A since each cable carries respectively 8A and 14A (example sum 4 yellow cables all from 14A I get 14Ax4 = 56A)

    Hi, do you connect the amplifier to the 2 jacks (RED-WHITE) behind the radio and the sub do you connect it to the amplifier? having a 250w psu is enough for sub amplifier and a 2x 60w speakers? car radio aiwa 40Wx4 Thanks Regards
  6. thanks I already understood this I would like to be sure that in + and in - (crossover) they must be connected to front speaker out (amplifier) for tweeters and mids respectively a + l and -l (if I want to put on the left channel) or a + r and -r if I want to put them right channel. so if I have 2 tweeters and 2 woofers do I need 2 crossovers (2 way) to cover both the right and the left front channel ?

    I repeat the question: in+ and in - where do they connect? because if I use 1 tweeter and 1 woofer in front in+ and in- go to front speaker out of the amplifier where there are two channels

    i have only a dmm it's a typo . i want say "connecting" the wires. thanks

    Hi, I have a aiwa 40Wx4 radio connected to a 250W PSU with a 60W speaker I would like to know which is a good amplifier where to put 2 speakers and a sub and how much must be the power of the PSU Thank you Greetings

    I did not understand how to use the dmm in amperage to measure the current on 12v joining all the yellow cables I could not distinguish them if I join the yellow cables of what should be the cable in mm or AWG? on this larger cable the fuse than it should be? since I get 22A the fuse must be greater than 22A? how much? the diagram of the psu I do not have it

    you are right it may be that it is consummated and I do not see it or see it only yellow yes I have a DMM What should I measure to identify the cables? how do I put the psu in safety? Do I have to connect the frame with a cable to the ground or do I have to put it in a wooden box? if I connect the 2 cables with different amperage and their sum gives me about 22A after I have to put a bigger type 1.5 or 2.5 mm cable? the fuse higher than 22A? Thanks

    Hi, so if I understand correctly I have to cut the cables that I need a couple of inches and put a fuse on + 12V. how much must the fuse be? thanks

    There are no yellow cables with the black stripe and I've said it several times and even the images speak for themselves

    Thank you What would I need an AC-DC converter if the power supply does this already? - How long should the cables be long if they are cut? - given that there are 2 lines at 12 volts with different amperage and considering as hypothesis that they are only yellow cables, then connecting all the yellow cables you will get an amperage of 22 A enough to power a radio. -so only a fuse would be enough? -and anyway I imagine that a 250w power supply is not enough if you want to add an amplifier and a sub. so I should cut all of the color diffrent to yellow (+ 12v) and black (ground) connecting all the yellow cables and all the black cables together and at this point put a fuse on the yellow cable and a fuse on the black cable correct?

    then I took the yellow cable and a black one separately this means I have 14A flowing? (I have not connected them together)

    Amplifier -- Sub -- PSU -- Speakers

    there are no yellow / black wires there are only yellow wires I got a yellow one like + 12v and a black one that is the ground at this point I do not know what are at 8A and 14A how to distinguish them? i dont understand this: "just sum them on a copper binding post" and what is the sufficient power required to put an amplifier and a sub + 2 speakers?( this is my first question)

    the cable connections are already made as you can see from the photos and the cables already cut and insulated. I would like to know now what I should do to secure everything. and what is the sufficient power required to put an amplifier and a sub + 2 speakers there are 2 lines at 12v with different amperage (+ 12V1DC-8A or + 12V2DC-14A) where is it better to connect the radio by choosing between the two? how I identify the two 12V lines since the yellow cable is 12V and the black one is the ground

    Amplifier -- Sub -- PSU -- Speakers

    Hi, from the PSU I only used the yellow and black cable (from the 24 pin molex I did not get them because the yellow and black cable are present) I can not remember if it's + 12V1DC-8A or + 12V2DC-14A the fuses are: 15A yellow radio cable 0.5A blue radio cable I connected green (molex 24 pin) + black to a switch to turn on the PSU I isolated the orange and blue cables from the radio molex 4 pin (2 yellow + 2 black) is not used I cut and isolate the sata cables. psu is leaned on the wood momentarily and the cables are insulated and free so what should I do? radio cables : -yellow _+12V -black _ground -red _switch -orange _illumination -blue _antenna remote

    thank you however I'm not going to connect amplifier and sub for now because I imagine 250W are few. it would take at least 500W. correct? (omitting for a moment amperage and voltage) "you are therefore better by cutting the molex and adding them on something metallic and isolated to avoid sparks, etc.," you could send me a picture and kindly tell me how to do and which wires to cut the 12V I took from the largest molex (24 pins), the other molex are free are not connected to the ground. until now using the low volume radio there have been no sparks or problems

    yes, i have already connected the radio to psu 250W with a 60W speaker front right
  25. Hello, I have a car radio aiwa (40Wx4) that I connected to a PSU 250W fsp, with a 60W speaker. On the back there are 2 REAR jacks (RED-WHITE). - Are they the amplifier input or can you connect other speakers already pre-amplified by the radio? Thanks Greetings
