And not one time did I mention to purchase an alt with high idle output. I did, however, say one that is more efficient at lower RPM. Example, my 240 Singer has output of 250A+ at 3k rpm. Now, where I live, and the daily driving I do, I don't see much of 3k rpm unless going up a hill near my job. I said he should purchase an alt based on his driving conditions. never said to get an alt based off of idle output

Ok im going to put 2 fi sp4 12's in the trunk facing the cabin and seal it off and just put everything else behind the box and yes maybe about 1k for mids and highs maybe not even that much maybe about 700 or 800 watts rms. I already contacted singer and im going to get the hairpin 370 amp alt. With a d3400 under the hood

Just trying to see if i can get by with one north star sms agm 480 insted of just getting 3 xsd3100. Will it work ? 12's should work great in 4.5 cubes correct ?
