How to wire rca cables into head unit?

[Anfield]

On my headunit there are no additional ports in the back all there is is the block connection bit do i need to take a feed from one of the cables or more than one. Ive got connection block thats not a problem, im just wondering which wire/wires to feed from?

No, the block conector (ISO) is high level output. to wire to RCA, you need line level outputs.

What are line level outputs?

The difference between line level and high level is basically high level has already been amplified and ready to be sent direct to speakers, whereas line-level is simply the unamplified audio signal. Equiptment requiring RCA inputs generally require the unamplified audio signal.

I did a little searching on the web and i stubled across a website called fleebay and would this do the job?

what for? if its a high-level to line-level converter your after, they aint all that good to be honest. At high volumes, they can suffer from clipping and hissing at low volume.

What is it your wanting to do?

i am wanting to buy an amp to power my sub in my boot whihc i allready have. at the min i have just got it feeding off my right rear speaker with bass full blast and its not really that bassy at all so i would like to get an amp to beef it up. but i dont have any rca output in the back of my headunit

Some amps will accept high-level inputs, so thats one option (wire directly from your rear speakers to the amps high level input) or to do a proper job of it, upgrade your headunit to one with RCAs (aka Pre-outs) and do it that way - HEADUNIT RCA > AMP > SUB

EDIT: in my experiance, the second option produces better bass at better quality, so i would strongly recommend that route.

if i was to go for a amp with high level inputs would this one be ok#?]

Go for this rather than the FLI http://www.caraudiodirect.co.uk/jbl-gto752-p-4139.html?cadid=5a14dbb3a8595527ffccd0dc0082240f

I dont know about high-level inputs other than they're meant to be rubbish. You really need to get a headunit with RCA preouts and run an RCA cable to the amp RCA inputs

Im not going to invest in a new headunit just quite yet. Ill just run my sub off a feed near my rear speaker for the time being. Its ok but not the best but for now its ok.
thanks for all your advice and answers

maybe in a year ill upgrade see how it goes
