Ok. Simple test to check if your subs are blown. Hook up speaker wire and simply touch each wire to each end of a new aa battery. You should hear like a sizzling static sound from the sub and it should jump slightly if its good. If subs are good you may be having issues with the connection terminals or worse. And it could simply be the audio connection from the stereo or the audio wires need replaced. Possibly replace the stereo or amp. So many more options but this should get you headed in the right direction.
okay , well you need to make sure all your conections are in the right spots, and that your IN LINE FUSE, between your amp and battery, the big glass one is not burnt, just take a look at the metal piece inside , if its a sold metal piece its good, if its burnt in half like a broken bridge it needs to be replaced. the next thing is the fuse on your amp, you need to make sure it is not burnt also. Check your remote that it is hooked up to the right wire. then check that your sub/speaker wires are connected properly and secure. YOUR GROUND WIRE IS HUGE HERE also. MAKE SURE IT IS GROUNDED TO A GOOD SPOT, YOU MAY HAVE TO MOVE IT AROUND A FEW TIMES TO FIND A GOOD GROUND!!!! if you check all of these things, it should work fine.. you can fiddle with your amp and bass settings levels. turn em up so when it works you know it, but not too much you dont wanna blow nothing :)
you may need a new head unit. it sound like you have lost the fron rca hook ups on your unit. common prob. usually cause by a surge traveling then the rca cables. i myself have had this happen and there is nothing you can do to the unit to fix it.
If the sub isn't working, you won't get a pop. All you need is a small speaker. Don't need a sub, you just want to test the sound. I recently blew 2 subs, no smoke, no smell, no sign of being blown. Absolutely nothing from the subs.... In the past my sub locked up. You can take your sub out of the box and hook the + and - to the battery to see if you can get the sub to pop there. I believe a small box will push a sub into a deep excursion to the center of the cone. I have 2 lanzar VW12D's that just quit. I hooked a 6 x 9 up to my amp and low and behold I had sound! Try that and see what you get...
You can also test the output with the multimeter. Set the multimeter to AC volts. If it's not an auto-ranging meter, set it to a voltage range of ~2v AC. Disconnect the RCA cables from the head unit. Touch one meter probe to the outer ring of the head unit's RCA jack. Touch the other probe to the metal contact in the center of the RCA jack. With the head unit near full volume and a clean signal source, you should read at least one volt on musical peaks. If you have a bass disc or a test tone disc (~60hz sine wave), use those.
The amp is rated to run a 2 ohm load on each channel. To do this, connect the voice coils of one sub in parallel (tie both "+" on the sub to each other and both "-" on the sub to each other), then connect that sub to one channel of the amp. Repeat this process for the other sub and connect it to the other channel on the amp. The subs will be in stereo and the amp will be outputting it's maximum power.
Are you certain you put the wires back on the amp the exact way they came off. I am not familiar with this amp but most amps if you look at the terminals where the speakers hook up there will be a plus and a minus. And generally there are four terminals. hence stereo plus and minus left and right. Some even have eight for, four channels. Since the amp is on, not getting hot and you tried two different audio inputs I would suspect speaker wiring or maybe the stuff you put in your trunk bumped a switch on the amplifier. I know this is not the exact answer you are probaly looking for but it is at least a place to start
