ironderby Posted August 20, 2011 Share Posted August 20, 2011 Okay so the head is: 4 ohms output power 2x500 rms into 4 ohms, the cab i would like is a 4x10 (4ohms) am i alright to connect them, will anything blow? thanks Quote Link to comment Share on other sites More sharing options...
Musky Posted August 20, 2011 Share Posted August 20, 2011 (edited) Hmm... I'm sensing a theme to these threads. I know it's boring technical stuff, but you really should try to wade through the wiki. [url="http://wiki.basschat.co.uk/info:amps:impedance_and_wattage"]http://wiki.basschat.co.uk/info:amps:impedance_and_wattage[/url] - it's not too bad if you ignore the odd equation! A short summary for the time challenged: [list] [*]Speakers are rated by their power rating in “Watts” and their impedance in “Ohms”. [*]When matching a speaker to an amplifier you should obtain the power ratings (in Watts RMS) and relevant impedance (in Ohms) values of both. [*]For a transistor amp, as long as the impedance (in Ohms) of the speakers is the same or higher than the minimum impedance of the amp you're safe to use them together. [*]You can use any power output amp with any power handling cab. If any of these combinations makes bad sounds (like distortion) then turn down and/or stop cranking the bass EQ excessively or damage may occur to the speaker. [/list] But to answer your question - you will be fine with that combination. *Edited to clear up a possible source of confusion.

If it's not then you will blow something. Edit: If you're talking about the LG1000 then it's not bridgeable, so to get maximum juice out of the amp you need 2 cabs rated at 4ohms each Edited August 21, 2011 by DirkThrust Quote Link to comment Share on other sites More sharing options...
