Hi, Can I replace all my speakers, But keep the original head unit as I have a working MMSC unit with modern Mitsi 10 disc changer,

Also would it be okay to use all the original wiring

I really just want to replace the speakers.

Think you may have to swop wire because Mitsubishi use a common ground  8-)

Ps where  are you in fife I'm just across the river in falkirk

don't most vehicles use common ground? Or am I interpreting it as something else?

Hi Near Glenrothes

I'm not the only L400 round here either I have seen two others several times within a few miles of my house.

You would be much better off replacing the speaker wires.

The resistances of the original speakers are weird and you'll damage your new ones if you use the existing wiring.

I would leave the wire as it is and replace the speakers with same impedence/ohms,

The poweramp stage of the radio is the important bit, All power amps have an impedence rating that you must not go below, EG 4ohm would mean you can put speakers of 4ohm or above, if you put a 2ohm speaker in you run the risk of damaging the power amp not the speaker,

Best thing to do if the speakers you take out have nothing written on them is put a multimeter across +/_ terminals of speaker and measure ohms, a 4ohm speaker should flicker around 4 ohms.

Replace speakers with same impedance and you won't damage anything.

impedance  is the ac resistance , and varies a lot with frequency, being lowest at bass, and highest at high's.   the figure given is usualy lets say, 4 ohms at 1000 cycles a second"( 1 KH,)  and matches pretty closely the dc resistance you would do with a meter"  as for cable " the thicker the better \" especialy for the high frequencies, " thin cable used in the Deli , has around 2 ohms per 3 meters,, (not the best )

[swampfreak]

don't worry to much about the cable, it really won't make much difference to the ear.
Do a little test, take a speaker out and add 5m of the worst cable you can fine, and tell me you can hear a massive difference. NO WAY.

Wire size AWG         Resistance per foot (ohms/ft)
               18                        0.0064
               16                        0.0040
               14                        0.0025
               12                        0.0016
               10                        0.0010
                 8                        0.00063

As a pro sound engineer for 27 years, Honestly don't waste ya time with cable runs,

Then try QED 79 strand " and tell me there is no difference "??   there is " even cooker cable if you could fit it in would be a massive boost "  fitting 10,000 watt sound systems in reggae clubs that is what we used , no loss whatever " on 40 18" bass units " the people with the lowest output need the biggest cable" Simples "  the bigger the cable the less loss and the better quality "  OFC" is best " especialy on  the line levels "

[Yojimbo]

This is about car installs though, the distance is so small you'd lose more at the connectors.  There is no doubt cable matters, but over a few meters, you probably won't notice it.  And to be a pedant, you can't say cable matters and yet with certain cable there is no loss at all, there is always loss, thats science. You Can't have your cake and eat it too.


So always buy 2 cakes!

[freddread123]

Your right ""  the connectors would lose more " lol  seems one should get the best cable one can afford"  i did notice in my un branded - stereo that is 45 x 4 ,,, that inside the connectors are very heavy and gold plated  from the mosfets out ""  and at 1KH  on the scope actualy produced 52.5 watts per channel all channels driven " with very slight clippng at 56 watts "  and that is from china "  , one pays one's money and takes the chance "

Wow looks like I opened a can of worms,

So I need to find out the Ohms of the original speakers,

Also I plan to use the original MMCS head unit, I don't want no window shaking power bass just a bit net than the farting speakers I have now.

Yeah, actually as I think you mentioned on another post, the power feed is actually really important, that was a good post, drop in output is a drop, but thats all, drop in power feed line will end up upsetting everything, once the voltage running the radio drops down, it simply won't work right, so a lot of clipping occurs.  I was reminded of this when I got a Sony xplod stereo recently, the main feed line went to an iso connector, but had a spade connector teed off the constant +ve line so you could also tie in a direct connection to the battery.  A nice design feature.  If you are worried about loss, make sure it happens on the output, invest on the input ;-)
