I have an old eclipse 34220 premium amp that i have no idea what the specs are on it? the 34230 seems to be a 375X2 amp so i am assuming that is close to what i have. I am basically curious if this amp is good enough to power a 10" sub say from the JL audio line or something comprable to JL audio. I called the eclipse info line and they weren't much help at all. If anyone has any details about this model and if it is worth keeping for the time being so that i can spend some money on other parts of my system and buy a good sub amp at a later time it would be much appreciated.
