Well when i took my amp out of my car about 5 months ago because my sub was sounding bad. The amp was working at the time i unhooked it. Ive reinstalled everything and can not get power to the amp. I hooked it up to my roomates wires in his trunk and still no power. I opened it up, and go figure a wire is loose inside. It is the ground wire and the solder on it broke and i cant tell where it is supposed to go, does anyone have a picture of the internals of this amp?

make sure your amp can hold either .5 ohms , 2 ohms or 8 ohms...... by my guess your amp is either 2 ohm stable or 4 ohm stable and you have them wired down to .5 ohm.....this will cause it to overheat and kill your amp. check out the12volt.com it will give you wiring guides for hooking up subs.
Sounds like you are over working this amp for sure.. Upgrading your power wire & battery might help, check your gain level on your amp to. This is not the volume for the amp. Its to get both amp and the cd player on the same page... And most of all if your subs are wired up to .5 ohm stable, see if your amp do the same... My answer to this ?? Upgrade your amp, Boss audio was never a good company to me, but that is my opinon. Audiobahn set up all the way..
It's not bad, but at 400 watts, it's a bit underpowered It'll be plenty loud, but the amp will distort before the speakers do, particularly if your subs are wired in parallel (as dual-driver boxes are typically wired)
Listen for distortion, and turn it down a bit if the sound gets fuzzy or static-y sounding
i have come across a similar problem before. if you are using the ceramic (glass, clear) fuses the solder in the end caps sometimes melts. you will not see the fuse blown, but the fuse may still be bad. try a new fuse to see if that works. also make sure no single stray strands of wire from a positive or negative wire are touching on the terminals on the amp. i hope this helps. ill keep thinking of other things in the meantime
Make sure the BOSS isn't in "Protected" mode (Red led lit) and connect the speakers properly (check the connections if they are in "bridged" mode). Also, make sure you set the cross-over, bass boost setting, bass volume control and the bridge mode according to the speakers you are connecting. Check the input level too. The BOSS amplifiers are of very poor quality and it can be easily broken. Maybe yours is broken.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is too low.
