I am unsure if i should wire my door speakers from my amp, i was told in halfords that wiring off the amp is dangerous cos you can dammage your speakers. so i was thinking about wiring my speakers from my head unit, only thing is the stock wire is crap, so im going to replace it but dont know how to wire them. it would be easier to wire from the amp, but obviously i am worryed about damaging my new door speakers.

it depends what watts the amp and speakers are

ive got infinity 5010cs components which are 75W rms. cant remember off the top of my head what the seperate outputs are on the amp, but ive got a jbl gto 4000 which is a 600W amp.

ive just had a check in the manual and it says it can have 4x 75W at 2 ohms and 4x 50W at 4 ohms and briged out put at 4 ohm 300W

if the rms input is 75w you should be able to run the speakers off the amp. If you need to wire the speakers at the front the wiring on the iso for the front speakers is

white - left (pos)
white / black - left (neg)
grey - right (pos)
grey / black -(neg)

If you buy more ICE look at some of the companies websites what you want to buy their products and see if they have a dealer near you. I find that people in halfords don't have a big knowledge of car audio. The shop where I brought most of my audio are one of Vibes recomended dealers. Also with shops what just do car audio they have a bigger knowledge of car audio. The place where I go see lots of brands like Vibe, Mtx, Fli, Sony, Kenwood, Audiopipe and many more.

you dont need to amp door speakers, simply use the existing wires with a connector, not a lot of money for the adaptor wiring!!

Most speakers are 4 ohm resistance so your amp is pretty much what mine was - 50w per channel which will run your door speakers fine without damaging them. just make sure u keep the gain on the amp down and dont push them too much
