Anyone ever try running a mav turbo belt on a Defender? Its a 1/2" longer and supposedly lowers rpms at the same speed.

With the 30% gear reduction in the portals and big tires Low gear tops out at 10mph. Most of the guys I ride with X3s and Renegde 1000s. These are mostly hard pack dirt roads. I haven't pulled the clutches. The portals were purchased new from an authorized Super ATV vendor who owns a fab shop near me. Its only been ridden in deep water and mud twice since I bought it. No mud or water in the belt box. Just a ton of gray dust but I blow that out every time with my compressor and air gun.

I've got a 2020 Defender Max HD10 on a 6" SuperATV lift, 4" GDP portals running 38" Quadboss QBT680s. on 20"s. Despite all the mud mods 90% of the time I ride dirt roads. I bought it from a friend so I know it hasn't been abused. It was completely stock when I bought it and I did all the mods the first week I owned it so I don't know if it did this before or the mods caused it. Since March I've been through 6 drive belts. They look like rats nest when I replace them. Just put a new factory belt on last week and now its gone into limp mode several times. It says Check Engine but its not overheating and I've changed the oil every couple of weeks since I bought it. Could the belt issue cause the limp mode? Everyone I ride with has a different opinion. I've heard I need performance clutches to turn the tires, I need more gear reduction in my portals, just get a clutch kit. I'm more concerned with the limp mode since this last belt change. Its shredded belts several times before but never got limp mode till this one, but its been every day since Edit: I did just install four 8" speakers in the roof, two 12" subs in the bed and two Skar Audio marine amps with a DS18 INH-90 battery. Could an electrical issue from the install cause limp mode? The pic of the gauge cluster was tonight, riding dirt roads maybe 25-30mph

So I swapped in a DS18 battery and it helped a little but my mids and highs still shut down at higher volume. This was the largest capacity battery they make. Not sure where to go from here. A 2 farad capacitor maybe? The voltmeter on the head unit never dropped below 12.8 volts and was as high as 14.4 at times.

Thanks for responding. I've already got the 850 watt stator. I don't see one rated higher than that. just ordered the Odessey battery from Amazon. Hopefully that solves the issue. The MRX150 actually gives you voltage on the home screen. Its never dropped below 12.5 volts and has been as high 13.8. I figured that was the issue, just weird to me that its the smaller amp drawing less power that's shutting down.

I have a 2020 Defender Max HD10DPS. I've added a light bar, whips, rock lights, 4 x DS18 8" coaxials in the roof with a kicker 4 channel amp running those, and 2 x 12" DS18 subs in the bed with a Skar Audio 1000 watt amp pushing them. I'm running a DS18 MRX150 for the head unit. After riding for a while the coaxials will cut out but the subs continue to work. If its drawing too much power I would have assumed the sub amp would cut out before the highs and mids do. If I turn the volume down they come back on almost immediately. Turn the volume back up and they go out again. The longer I ride the lower I have to put the volume to get them to work again. Any ideas?
