Hey guys I installed a set of subs, with an amp in my car today. Im using a high level converter as my rca output. I used my two rear speakers off the parcel shelf. Now, the subs only work when i touch the positive and negative together for a split second...... If i start it and run the subs, they dont work. Amp powers on as well.... so the amp, power, is fine. it has something to do with the rca/high level converter?

have you installed a surge protector? it might be getting to much power and overloading.

no i havent, didnt think youd need one?? the fuse is set at 60A. When the car is turned off, then turned on. the subs wont work untill you put the positive and negative of the two speaker wires from the line converter together for a second, then they kick in...... And it works for the rest of the time the car is on?

even if its not the problem you should still install them, stops from anything blowing up, so its a good investment, as for that, how good is the earth? you may need to clean them or it just might be a bad connection somewhere?

isnt that what fuses are ment for. subs work fine once the positive and negative for the line converter have touched for a split second, i dont know why it plays stupid with me. :S

What's a line convertor? Is that a speaker wire to RCA convertor?

Yeh, it is ^ also known as LOC's ( Line Out Convertors)

^ spot on, no one have any idea why? ive litrelly put them a mm apart, so whenever i hit a bump. it turns the subs on.... lol ---------- Post added 06-06-12 at 00:24 ---------- edit: the wires i mean

When I did that I ran the positive of each channel to centre pin of the RCA only, connecting the negative made it buzz and not work...

Here's a basic diagram Did you hook it up this way...? Some original photos have not been recovered yet.

thats exactly how i hooked it up.... edit: but the calais come with two extra subs in the rear parcel shelf. i just took it off those
