Old Skool Amp

[larryho]

Hi Guys, (Need Help)

I hav an old school amp and i juz understand that old skol amps does not hav speakers screw ports like those amps currently in the market in order for us to connect our speaker cables into. I would like to know, how can i plug-in my speaker cables into the amp?

There is a socket for me to connect a connector for the speaker cable if im not mistaken. Now im having a problem on how am i gonna connect my speaker cable into the amp, i hope pros around here will b able to help me out on this.

best to find a copy of the owner's manual or a diagram on the internet. simply connect later magic smoke appear. alternatively...email MTX lah..

 

[larryho]

mayb i'll juz bring it to a car audio accessories shop n c whether they can sort this out anot. I really hav no idea how tis amp works aso....haha.

 

[cacin]

base on what I can see, I guess the blue colour wire as remote wire.
the other 4 would be speakers. just need to guess which is +,- and L/R.

 

[larryho]

Thanks for the info cacin, but how to connect the speaker cables into tat 4 wires? Another thing like u said...which is L/R +/- aso tak tau lar. I saw aso felt abit pelik...1st time seeing tis type of old skool amp....haha.

 

[vishnnu]

wah,really ol skool one.......

 

[angeldeservetosleep]

if the L/R tebalik jz change the RCA cable... easier liddiz... :P

 

[larryho]

But which color is L/R or -/+ aso i duno.....haha. I bought the amp becoz i though old skool amps will b quite good as i heard alot of rumour tat old skool amps r more stable...not really to sure about tat until u i try it. :proud:

can you tell me what are the remaining wire colours?

I can see white, green, black and black with white stripe. is that correct?

so, again, I assume that the blacks are negative. so, white and green are positive.
connect 1 speaker to white and black with white stripe.
white to speaker + and black(white) to speaker negative.
connect 1 RCA cable from HU to amp L RCA, power on HU. got sound from speaker? If yes, then the 2 wires are for the Left Channel. If no sound, try to move the RCA to amp R channel.

got sound? if yes, then the pair is for Right Channel.

If still no sound -> probably chosen the wrong +/- pair or that channel is dead?

when you do this, start with very low volume on the HU. you just need to hear sound coming out from the speakers. doesn't need to be loud.

to use the wires, 2 choice:
1. cut the wire near the blue colour connector and strip it. just connect your speaker wire to the exposed wire for testing. Actuall installation would require better connection (solder/spade connectors).
2. buy the 'male' version of the same connector. got sale in shop.

here's examples of some connectors taken from www.bcae1.com

hope this helps.

for bridging, it's going to be a bit tricky because the manufacturer would recommend which wire to use from bridging, some use + left and + right, some use + left and - right. So, this is going to be tricky :)

if you have a multimeter, probably can test/check.

anyone knows if in bridge mode, would the other not used wire have signal?

 

[larryho]

I might be bringing tis amp to an car audio shop to check out whether they can solve this prob anot lar....better. Im aso not pro in this...hehe.

 

[angeldeservetosleep]

bridging jz takes L negative + R positive or L positive + R negative. jz vice versa both also can... :)

 

[larryho]

Now i dun even knw which wire is for +/- and L/R, so hw am i gonna bridge it aso i dunno coz i still cant identify the wires.

 

[bafukie]

you have to google for the manual to know the exact l/r and +/-

 

[larryho]

I've tried googling, but still cant find the answer. The previous owner also told me that he cant remember which color is for -/+ L/R. So now the only way is to check out n c whether any car audio shops knw about it or not.
