rockFord_Expedition Posted November 8, 2014 Report Share Posted November 8, 2014 are the subs single or dual voice coil? Old School/New School RF Build March 2015 SOTM Winner How to crimp large wire Link to comment Share on other sites More sharing options...
rockFord_Expedition Posted November 8, 2014 Report Share Posted November 8, 2014 That will "work" but I have a question for you, is that amp a/b class? It's potential could really be brought out if you use it for mids/highs Old School/New School RF Build March 2015 SOTM Winner How to crimp large wire Link to comment Share on other sites More sharing options...
ChevyBoy95 Posted November 8, 2014 Report Share Posted November 8, 2014 Assuming they are all SINGLE 4 ohm voice coils... 1. You can run all 4 on 200w each (underpowered) "- 4 x 200w rms @ 4ohm" 2. You can run 2 on 500w each bridged "- 2 x 500w rms @ 4ohm" 3. You can run all 4 on 375w each (underpowered), 2 paralleled per channel and bridged "- 2 x 750w rms @ 2 ohm" Best Score to Date : 160.5 dB Outlaw (47Hz)[4 XM 15's & 2 Taramps Bass 12k's] BL : http://www.stevemeadedesigns.com/board/topic/147800-chevyboy95s-4-15s-7krms-wall-1533-db-on-half-power/YouTube: http://www.youtube.com/hitemwiththeflex/ Link to comment Share on other sites More sharing options...
ace_ventura Posted November 8, 2014 Author Report Share Posted November 8, 2014 the amp is a class a/b amp and the subs ar dual 4 ohm each so wire 2 subs to channel 1and2 for a 2 ohm load and the other to to channel 3 and 4. will this play good or not? i think the amp gives more power than rated do Link to comment Share on other sites More sharing options...
rockFord_Expedition Posted November 8, 2014 Report Share Posted November 8, 2014 Do this on each channel. With the differences in power you are talking, the cone area will make a bigger difference than the power. Do you have room for the enclosure required?

ace_ventura Posted November 8, 2014 Author Report Share Posted November 8, 2014 so that would give 500rms to 2 subs. is that enough? yes i have the room for the enclosure needed Link to comment Share on other sites More sharing options...
rockFord_Expedition Posted November 8, 2014 Report Share Posted November 8, 2014 Make sure you match your gains... You could even run 1 per channel @ 2 ohms to get 350w a piece to them Old School/New School RF Build March 2015 SOTM Winner How to crimp large wire Link to comment Share on other sites More sharing options...
