    I agree, the first thing to do is to run the head unit straight to the amp. If the problem remains, check the shield ground for the head unit.

    have you tried bypassing the EQ? A slider or rheostat may be faulty. Do that, and post back your results.

There has to be sumthn hooked up wrong bc i have had same problem with my 12' subs but it was simply a matter of my rca jacks but sense you have checked them try rewiring the speakers if that does not work then your rca module may be burned out within the amp..iso then check the amp by taking the cover off and making sure nuthn is burned on the inside.or if any wires are loose or touching.

What would cause my fossgate t1500 to shut off everytime the bass hits hard I have two t12s that it pushes


Sounds like your amp isnt powerful enough to power your subs, whats the wattage of your amp and both subs? Its shutting off when hard bass hits to protect itself from blowing, a good feature as a blown amp means a new one. an amp should always be more powerful than the speakers / subs you are connecting to it. for 2 500w subs your looking at a 1200w amp minimum.

THUNDER 5601 WHEN VEHICLE TURNED ON, SUBS BOOM, THEN WORKS OK. ALSO WHEN RADIO TURNED OFF


If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.

Let me know if you have any other questions.

Improper function


try hooking up your subwoofers in series. then connecting them bridged to the amplifier. as follows: positive from sub#1 into positive of amplifier left channel.. negative sub#1 into positive sub#2. negative sub#2 into negative amplifier right channel. turn the gain down as this will sound pretty loud.

Added another amp to system now subs dont hit as hard


This sounds odd, but try putting your subs out of phase from the mains. Just see if it changes anything.

Diferent sound


The entire difference may be due to the vehicle.

He could check things like the B+ reaching the amps when driven hard. It should remain well above 12v. If it's dropping below 12v, that could be part of the problem.

He also needs to check to make sure that all woofers are in phase. If he has one woofer connected improperly, it would only be approximately as loud as one woofer because one would be cancelling another out.

Tuning the amp


St the crossover to LP (low-pass), and around 80Hz for 12" subs or 120Hz for 10" subs. Turn the gain all the way DOWN. Turn the radio about 3/4 or 4/5 the way up. Adjust gain until subs start to sound a wee bit sloppy and then adjust back 1/8 of a turn. Also, DON'T turn the LOUD function on or the BASS all the way up on the radio.... these should really be flat as possible.
