WilliamH Posted July 20, 2015 Report Posted July 20, 2015 I am thinking about putting some subwoofers I the back of a blazer. I have everything I would get to do this all figured out. I would be running a Rockford Fosgate prime r250x1 prime amplifier, and a Rockford Fosgate r2sd2-10 prime subwoofer. Would I need to put a bigger alternator on it if I were to just do one amp and sub? Also if I wouldn't need to do an upgrade with just one, could I get away with two subs on the stock alternator and battery? I am pretty new at this but I do have the basics apart from that and I just wanted to seek your opinions. Thank you for replying, if you do. Thank you for reading it all if you don't respond anyway.
reedal Posted July 20, 2015 Report Posted July 20, 2015 The amount of subs doesn't affect how much power you can supply, only the amplifiers. On that little bit of power, no, you're fine with just stock alt SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32
WilliamH Posted July 20, 2015 Author Report Posted July 20, 2015 Thanks. I just didn't want to mess the old girl up.
Broke_Audio_Addict Posted July 20, 2015 Report Posted July 20, 2015 You'll be just fine with stock electrical for 250 watts. Just make sure you order the right subs to match up with the amp. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
