Will a D2700 and 160a Alt be enough for 3000w rms?


Recommended Posts

I have a 2011 Dodge Ram 1500 with the 5.7L Hemi and stock 160a alternator, big 3 upgrade with 1/0 ofc. I will be installing a 3000w rms system (two 1100w rms mono amps and one 800w rms 4 channel). My stock battery group is 94R (11.9L x 6.88W x 7.48H). However, I have a little room to spare in the battery tray - about 1" in length and 2" in height. From looking at the XS Power website, it looks like the D6500 and D2700 should fit in the stock starting battery location, but the D3100 looks to be a bit too long.

I am thinking three possible options that I need your guys help with:

1) Do you guys think the D2700 and my stock 160a alternator will keep up for daily use while the truck is running (don't plan to listen to music with the truck off)?

2) If I can make the D3100 fit, would a single D3100 and the stock 160a alternator be enough?

3) If stock alt and D2700 (or D3100) is not enough, could I get away with a 275a alternator (Singer or DC Power) and a single D2700 battery?

I still have my backseat in my truck. There is no space in the backseat for extra batteries due to the sub box being under the seats and the amp rack being behind the seats, so finding a place for an extra battery would be difficult if not impossible.

Thanks guys!

3100 won't fit in stock location in Chrysler dodge jeep without heavy mods its about 1-3/4 inch to tall go for the 6500

he wouldnt be the first to say they did a 167 with a system like that (one that clearly DOESNT), but i have to say, he didnt beat me anywhere, ive never competed against the guy. If he thinks his does a 167, mine would probably put him in a coma. :hairtrick:

THEKINGsBACK - Ok. From looking on the XS power website, the D6500 measures 11.8 x 6.81 x 7.25, and the D2700 measures 12.09 x 6.65 x 8.31 (L x W x H). The D6500 has MAX Amps – 3900, CA – 1070A RC – 150min. Ah – 75, whereas the D2700 has MAX Amps – 4300 CA – 1170A RC – 185min. Ah – 100. So you think the D2700 being 3/4 of an inch taller than stock won't fit?

Would a single D6500 and the stock 160a alternator be sufficient?

2000s-10 - the mono amps are new Hifonics brx1100.1d and the 4 channel is an MTX 7804. The monos will each power a sa-12 d2 and the 4 channel powers (4) JBLGTO938 6x9s. Amp gain with be professionally set with oscilloscope.
