Hello, I bought 2 x the Earthquake SWS-8 and with it ne groundzero GZTA 2500 TX So far I thought a “one channel” amp also has a connection. Then both would be connected together, the whole on 2 ohm and thus the AMP 500 RMS (woofer each 150) does so would be enough and still reserve! But now I found this in the manual: the gzta 2500 tx has 2 connection terminals. How do I have to wire it then, that it really runs on 2 ohm ? like on the picture – or I have to put both together on e inen channel connect. gruss, dognose
