hooking up a system..
got a crappy headunit/decent amp/great sub...
500 watt jensen amp
dual crappy headunit
JL sub..
ran all the wires..plugged it in, and didn't work...
the amp power isn't turning on..I used an existing 12 volt(remote one from head unit), that stopped at the seats and just added more wire to it...wonder if its dicked some where? or would it still power up with the battery?
also i just drilled a new hole for my ground, is that alright? do i have to sand around it?
what could be my problem, and is there a stock amp too?

dual is better than people think, jensen however is garbage. the remote wire is not intended to supply 12v to power anything. you need to get a direct connection from the battery for the amp then connect the remote b+ to the head unit.

it's probably for the best because jensen really is garbage. there are plenty of good amps available from crutchfield.com. although generally speaking expect to pay $1 and change per watt on these amps. i've installed stereo systems within all price ranges on personal vehicles and on those of friends. so believe me when i say that the most important components are the head unit and wires.
then depending on how low and the intensity you want from the bass you can decide if you want to spend more money on a good amp. the speakers are really the last thing you should take into consideration. if your head unit sucks the amp will only amplify a weak signal which will sound like crap regardless of the speakers.

You're on the right track as far as troubleshooting is concerned. Here's the list of posiblities I can think of. If you have a multi-meter or a test light, check for power and ground at both battery and accessory ends of the wires. Check the ohms on the ground. Closer to zero ohms the better! Check your fuses on the amp and the car radio fuse. If everything is wired correctly and gain is turned up on the amp and still doesn't produce sound....Your amp is toast.
RECAP
1 - bad ground
2 - open (broken or not connected) wire(s)
3 - blown fuse(s)
4 - blown amp
