hamerhead Posted July 28, 2013 Posted July 28, 2013 ...wire an 8 ohm 15" sub-in-a-cab to the woofer of a powered EV speaker (model SxA250), using the LF amp to power both?
marcnorth Posted July 29, 2013 Posted July 29, 2013 Possibly your power amp.Is the other one 8 ohms too? If you hook the two together will it be a 16 ohm load? All I can think of would be, is the power amp rated for the ohm load? If it is no problem, if not it could burn up your power amp.added this link for a more suitable explanation:http://celestion.com/speakerworld/guitartech/39/Speaker_Wiring_Configurations/

If it is no problem, if not it could burn up your power amp.added this link for a more suitable explanation:http://celestion.com/speakerworld/guitartech/39/Speaker_Wiring_Configurations/That was what I was thinking too. We don't know what kind of amp is in the powered subwoofer. Could be a class D, could be an A/B BASH amp or simple A/B. Even then, we don't know what its safe ohm ratings are. Do we know the rating of both woofers? If the amp is designed specifically for that speaker and nothing else, it may not like the extra load. If you wire in parallel for the two speakers you drop the impedance in half or thereabouts. If you wire in series, the total load is the two speakers' impedances added together. Parallel (lower impedance) increases the chance of the amp overheating; running in series cuts the amp's output in half (but then, you have two drivers).
gorch Posted July 29, 2013 Posted July 29, 2013 It may depend if you wire the speakers in series or parallel.
dragan Posted July 29, 2013 Posted July 29, 2013 It may depend if you wire the speakers in series or parallel.and the ohmage of the ev speaker & load rating of the ev power amp. series giving a larger load may run but not improve low end , parrallel giving a smaller load may blow the power amp if run below the amps load rating
hamerhead Posted August 4, 2013 Author Posted August 4, 2013 I really want to, but those EVs are expensive.That, and I have a rule about putting down a beer.
