Dont know whats wrong

To be on the safe side without further information I would hook the two subs up in series leaving you with an 8 ohm load.

Check your RCA cables to make sure you are getting signal. The amp isn't in protection is it? Also, if you have a multimeter, you can check to see if you are getting any power out to the speakers. Also, check to make sure your subs aren't blown. Keep me posted.

Get a dual vented box for them. Not some cheap stuff either or it wont last. Then make sure theyre facing the back when you hook them up. I know its weird but they hit WAY harder that way trust me.

i bought two Audiobahn A2300hcx on ebay for a little over 400. look around on ebay you can really score sometime dirt cheap........ Check out audiobahn amps, never did me any wrong...........

the best way to wire it is @ 1 ohm, but your amp has to be a 1 ohm stable amp. i'll attach some pics for you. this wiring depends on what ohm your subs are.

You have a 2 ohm stable amp, and dual voice coil subs.. The L7's come in both Dual 4 ohm, and Dual 2 ohm, so you have to know what impedance your coils are prior to wiring. HERE is a nifty little guide that will show you how to wire your subs. DO NOT WIRE THE SUBS LOWER THAN 2 OHMS ON YOUR AMPLIFIER!

make sure the impedance is right for the amp you're using. If you're using a 4ohm amp and a 2ohm sud that may be the problem. It may be overdriving the amplifer which is bad and can cause damage to the amp. Hope this helps.

you should use an amp with approx half the power of the speakers max output (i.e 1000 watt speaker use no more than 600 watt amp)

Series is +amp to +1, -1 to +2 , -2 to -amp . This way you have wired the two voice coils into one higher impedance voice coil.

Hi

maybe your voice coil is open circuit! or you have burn voice coil! thats why your unit is not functioning!

Thanks!!!!
