Wait? The bigger alternator will not help? How so? The alternator provides current to recharge the battery. If the renegade models came with a 160 amp alternator and the sport/limited units came with a 132 amp alternator than there is a benefit. The OEM made that statement. |

it will help, but only if you have a higher demand on the electrical system causing the 132amp alternator from keeping the battery fully charged at running conditions (14.4v). i tested the my alt. (132a) and it was putting out 142amps at 2000rpms at full load. EDIT: but yes a better battery could help also, i switched to a optima yellow top and it helped a bit. |

Whether or not a better battery will help depends on what hes wanting to accomplish. If he is wanting to run 10 100watt lights while having the heated seats in, rear defrost, front defrost(A/C is on), fan on high, fog lights on, etc, then a bigger alt would be best.

If you have the regular 132amp alternator and then add a 160amp one you will not see any gain.Why? Well the alternator on the KJ is totally controlled by the PCM and is programmed with the fact it came with a 132amp alternator.You will need to have the PCM reprogrammed to a Renagade to see the benefit of the 160amp alternator.Same goes with the MeanGreen 202amp alternator. I have the 132amp alternator,the renny lightbar,2 more accessory lights,a 750watt amp,and a WARN XP9500 winch and have never had any issues.I also upgraded to the Optima YellowTop battery.No dimming of the lights at night when cranking my stereo  .

Under the Back seat is a decent spot but not on the floor, I removed my back seats, and put 2 Kicker 300.2 Amps under there. I did have dimming issues, Until I got Capacitors. |
