I put an amp and subs in over the weekend and have no problem in daytime but as soon as I turn my hids on it kills the subs. I have 3 sets if hids and it has always effected my radio signal but never the actual output. The amp stays on and ur can feel very slight movement from subs . Can anybody tell me what's up and how to fix it?

Take your battery to batteries plus or any autoparts place and measure the amperage output. Add up the sum of the constant amps that your equipment is pulling (Truck electronics, HIDs, Amp, Deck, etc) and I would bet that you're exceeding the constant output of your battery...by quite a bit. My brother plows and uses strobe lights. He had to install a secondary battery to support the constant amperage needed to run his equipment. Unfortunately you can only count on the alternator for constant voltage....it doesn't contribute to the amperage rating required by your electronics in a "constant" way.
