Finally putting a new system in my si.
To start I will be running my sae-1000 and a eclipse 88150dvc dual 4ohm sub. I have a 1/0 run of cable from battery to hatch. Will my stock 90amp alternator keep up?
I do plan to get rid of the tiny underhood battery and use 2 group 65 AGM's in the hatch and add a 100-150x4 amp for door speakers and rear fill along with big 3. Will stock 90amp still keep up with that much draw with 2 batteries. I found a 130 amp alternator on eBay for a reasonable price. Would that keep up?
I'm not new to the car stereo scene, but this will be the biggest system I've had. And want to do it reasonably right.
