Z71TahoeSubz Posted April 17, 2013 Report Share Posted April 17, 2013 I have a z71 Tahoe and I'm planning on getting 4 obsidian 15s dual 4 ohms with a crescendo 5500w how should I run it? I also have a dual mount bracket with 2 alternators and a xs power d3400 battery as an extra in the back. I'm not worried about under powering it at all but what should I do to make sure i don't over power? Quote Link to comment Share on other sites More sharing options...
Ben Fultz Posted April 17, 2013 Report Share Posted April 17, 2013 1st thing would be to not power 2400 watts of subs with 5500+ watts Quote Link to comment Share on other sites More sharing options...
CleanSierra Posted April 17, 2013 Report Share Posted April 17, 2013 (edited) 1st thing would be to not power 2400 watts of subs with 5500+ watts Well he did say he was planning on getting D4 subs. So that is a final ohm load of 2 ohms. What's that beast put out at 2 ohms?*Edit- Just read on website that it puts out 2800 @ 2 ohms. It sounds like a good plan to me. You got all that power for the future too Edited April 17, 2013 by CleanSierra Quote Im not the one you want to try to troll. Just a fyi for you.

Ben Fultz Posted April 17, 2013 Report Share Posted April 17, 2013 I retract my previous statement, forgot about about 2 ohm option, since everyone and their brother seems hung up on .5 ohm or less wiring these days lol Quote Link to comment Share on other sites More sharing options...
Z71TahoeSubz Posted April 17, 2013 Author Report Share Posted April 17, 2013 the amp also puts out 1500 on 4 ohms which is a total of 6000 watts which might be alittle to much but obsidians are also very underrated and can hold a lot more power than there RMS actually sais Quote Link to comment Share on other sites More sharing options...
Z71TahoeSubz Posted April 17, 2013 Author Report Share Posted April 17, 2013 Still want to see some more ideas to decide what I should do ! Quote Link to comment Share on other sites More sharing options...
Nathan @ XSpower Posted April 17, 2013 Report Share Posted April 17, 2013 As far as overpowering the system with the alts and batteries there is nothing to worry about unless you exceed the amps high voltage input. You could have 100 D7500 and there is no way to over power the system. Batteries and amps only put out what the system is pulling. Quote Link to comment Share on other sites More sharing options...

That sounds good, another thing since crescendo amps are soo power hungry especially since I have a 5500 watt do you think the xs power d3400 with the stock battery and the stock alternator with a 225 amp powermaster high-amp alternator will be good for that setup and gibe the amp enough power?
