[QUOTE="Prowler573, post: 2346747, member: 561023"] He wasn't assuming that you power your amps via the HU. That would be an awful silly thing to do. But! His statement, as written, was entirely correct. [I]Everything[/I] that draws power in your vehicle, period, gets that power from the same source: the battery. So if there is anything in your car that requires a constant draw ~ which there is ~ (the clock, radio presets, and EQ settings memory in the HU for instance...and/or a factory clock in your car...engine computer settings, etc) there is going to be a spark when you reattach the positive post after having it disconnected. It's unavoidable, really. As to why your amps do not work now I'm not too sure, though...I've done the exact thing you did many a time with no adverse results. Check [B]all [/B]fuses...if nothing there pans out then try completely disconnecting the amps power and ground leads then carefully reconnect them then cycle the HU's power on and off a few times to see if it resets the possibly tripped protection circuits in the amps?? Outside of that I'm a bit lost [IMG]//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif[/IMG] [/QUOTE]
