New alternator..help?

[anders1127 10+ year member]

I had a 120 amp alternator in my 2012 Jeep Patriot, stock battery and stock alt obviously, powering a hifonics BRX 1100.1d powering a Sundown SA-15 in a 6 cubic ft box tuned to 32 hz, it burned out my alternator over time and it went out today, so I ordered the highest output made for Patriots, 140 amp. Do you guys think that'll be enough or what else should I do? I already had the big 3 as well. Suggestions or thoughts are much appreciated because I honestly am lost on this one. Connections were tight and everything.

Going from 120 amps to 140 amps isn't much of an upgrade. Were you running the battery down and relying on the alternator to recharge it?

I couldn't find any custom rebuilt H/O alts for my model and I don't have much money to have a company custom build one right now. Well not completely, I only played my music with the engine running and driving around, never once with only the battery on.

I had a custom one built by mike singer. He has great customer service nice prices and i have yet to hear or read a complaint about a singer alt. Well i take that back one complaint i heard was a user error he took the pulley off that mike sent on the unit and put the stock one back on causing the alt to not turn on at low rpms. I paid 449 for a large case 6 phase hairpin the first of that kind he made and it puts out plenty more then the 250 amps he rated it at.

I only had like 200 or so to spend, in the near future I want to get two v.3 15's with probably a sundown 2500, I'll definitely need to look into that singer alt..

Update: I got the new 140 in barely, the chassis of the car makes it nearly impossible to change it, especially if I got anything bigger, problem is fixed and the amp is getting plenty of power just from a 20 amp increase.
