Well, I'm doubt again (sorry, GlassWolf, and tks for the help): after dismantle the speakers that kept draining the batt. (350W-4way-Proaudio), I came to the conclusion that the terminals on the plug were badly crimped, 'cause I pulled the wires and they came out of the terminals!! We have a saying in Portuguese which says something like "If you want it done properly, do it yourself"... Now, is there a chance of this situation to make the current go up and down due to bad contact and therefore overheat the amp? On the other hand a friend of mine gave me a bridgeable 2-channel amp from Futura (FA-1051) to try and feed those two speakers. Is it worth a try should'n't I bother at all? TIA!
And to ocupy the remaining 2 channels of my alpine f356, do you think the 6" x 9" type R Alpine SPR 694a would be a good choice? How much would they cost? TIA!!!
