JBL GTO75.4 amp and 2-12" subs issue
Hey,
i have just installed my new MTX 4500 dual 2 ohm subs on the JBL 75.4 amp. My issue, is once i turn it up, the amp protects (cuts out), or it turns the light from blue to red, then back to blue. it then turns back on. I am wondering if these subs have to much draw? Would a stiffening capacitor help? I just had in 2-10" subs, and this was not a issue. The load is 2 ohm to the amp now. Any ideas?

my front channels (1&2) are powering a pair of 5 1/4's, ands the rear (3&4) are powering the subs. the load is 2 ohm. The subs are dual 2 ohm, into series ( 4 ohm off each speaker), then parallel to the amp to be 2 ohm.

I have that amp, and it is NOT rated to do 2 ohm mono. Stereo only.
The only way you can wire up the subs, is to put the coils on each sub in series, and connect them to the amp in series, but that will give you a final load of 8 ohms.
Of course that will cut the power to them from about 200W (at 4 ohms) in half to 100W, BUT the upside, is that it will actually work.
