The amp is hooked up properly and the power light comes on (green)but there is nothing going to the subs, is there anything i can test or check for inside the amp???
Hi
if you got a voltmeter
TEST IT ALL ON A LOW LEVEL OF VOLUME!!
check the outlets of the amp if there is a signal at all...
no? - the amp isnt hooked properly!
yes? - check if the volt level on the outlets is higher then the level on the inlets of the amp (the amp is amplifying)
no? - the amp isnt hooked properly! or its bad...
yes? - connect a speaker to see if its working
wont put out a lousy spark?
check your system, the problem if probably there...
check all the connections, fuses, wires
begin from battery and go FWD antill the next device isnt working
good luck

There could be a few potential reasons why you are not getting any sound from your subs even though the green light on your Power Acoustic amp is on. Here are a few things you can check:
Check your wiring: Make sure that all of your wiring connections are secure and that there are no loose or frayed wires. Check that you have connected the amp to the correct terminals on the subs and that the speaker wires are properly connected to the amp.
Check your settings: Check the gain and crossover settings on the amp to make sure they are properly set. Ensure that the crossover is set to the correct frequency for your subs and that the gain is not turned down too low.
Check your power source: Check your battery and alternator to make sure they are providing enough power to the amp. If they are not, you may need to upgrade your electrical system or add a capacitor to your system.
Check for a blown fuse: Check the fuse on the amp to make sure it has not blown. If it has, replace it with a fuse of the same amperage.
If none of these steps resolve the issue, you may need to take your amp to a professional for repair or replacement.
Yes, technically you can, however you will be putting both your sub and your amp at risk. One of the worst things you can do to a sub is underpower it. The easiest way to explain it is n ot giving enough power to the sub leaves it starving for power. The motor structure ends up working too hard to try and move the cone properly and what happens is the sub will usually seize up rather than blowing out in the term you usually hear (ie, I had my system cranked up and I blew my subwoofer).
Secondly, in an attempt to get any real sound out of the under powered sub, you'll probably end up cranking the gain and bass boost on the amp which ends up overworking the amplifier quite a bit and can in turn lead to fried out amp chips, burnt up circuit boards etc.
Thirdly, by maxing the gain bass boost you're going to end sending a lot of distortion through your subwoofer in an attempt to get some decent bass. Distortion kills both subwoofers and speakers alike.
So to answer your question, yes you can hook up your subwoofer to that amp and yes, it will probably play for a while but I wouldn't recommend it. Look for a class d or mono block amp to push your sub as these will give you the most power and best heat dissipation. They are designed to push subwoofers specifically and you will get better sound and longer life out of your equipment. A good rule of thumb is look for an amp within 100-150 watts of both your RMS power handling and your Peak power. Remember, when it doubt, always go a little bigger on the amp side of the spectrum. It's easy to "tune down" an amp by having the gain and bass boost at a lower level (50%, 25% etc), than to turn 'em all the way up just to get some bass and end up prematurely blowing out your sub, amp or even worse, both.
Check your safe light on your amp if it's green then the subs are **** but if you don't have a green light check your ground, just because it sparks when it touches dosen't mean it's a good ground so grind the paint off the bolt if need be. If all else fails get new subs, do your self a favor don't get lanzar products there horrible trust me on that one
it is probably the rca inputs on the amp may have fried. was your cd decked turned up loudly before the power went out? did any wires accidently touch each other? If had worked fine and then suddenly stopped, than either a wire came loose or the inputs fried. try using different cables and I also suggest disconnecting power for 24 hours and then reconnect. If the green light is on then it is getting power and the problem is in the rca cables or the inputs
Is the amp being fed directly from the head unit's RCA preamp outputs or is it being fed by another amp's preamp outputs? Try temporarily wiring up a speaker you know is good in place of the sub and see if anything changes.
