yea i'd look into a relay for your 3 remotes. but still 3? that's pushing it a little bit to close for me. If i were u, i wouldn't hook all 3 to the HU. Instead, i'd probably hook them up to the cig. ligher and from that either add a relay or even upgrade the fuse to handle a higher load. Once u fry ur HU, it's almost good as gone!
