ace_ventura Posted November 8, 2014 Report Posted November 8, 2014 hey guys i'm planning of buying a rockford fosgate power elite t1500.4 these are the specs of the amp online - 4 x 200w rms @ 4ohm - 4 x 350w rms @ 2ohm - 2 x 500w rms @ 4ohm - 2 x 750w rms @ 2 ohm i want to run 4 audio system xion 12 inch subwoofers on the amp. the subs are 4ohm 600 watss rms each. will this play good with 4 of them or should i use only 2 of them on the amp.
rockFord_Expedition Posted November 8, 2014 Report 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
rockFord_Expedition Posted November 8, 2014 Report 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
ChevyBoy95 Posted November 8, 2014 Report 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/
ace_ventura Posted November 8, 2014 Author Report 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
rockFord_Expedition Posted November 8, 2014 Report 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 Posted November 8, 2014 so that would give 500rms to 2 subs. is that enough? yes i have the room for the enclosure needed
rockFord_Expedition Posted November 8, 2014 Report 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
