Hi guys, looking for a secondary trunk power cell for a true 2500-3000 watt system. Amps are some oldschool class A/B current hogs. Already have a big deep cycle, 220amp alternator, and big 3 upgraded, just looking to really set it up right. Which XS cell is for me? Thanks!
I have a 2003 Chevy Avalanche With power/heated seats. This truck has a 105 ampalternator in it stock.
I am looking to install a CarPC system into this vehicle that will pull under 160W.
If I install the system I am considering I will have 6 "old school" unregulated 50MS Audio Art amplifiers that at 14 volts could max out at about 2000W.
Case rating of 2x50W but documentation rates these at 75x2 at 14V and 1x350 at 14V. Yes these were considered "cheater" amps when they were new.
My setup will be as follows:
2x75 driving Passive Diamond 3way Audio HEX speakers (6.5, 4, and tweet)
2x75 driving Passive Diamond 2way Audio Hex speakers (6.5, tweet)
1x350 or 2x75 driving 6.5 HART series Subwoofers (80-150hz roughly. Will use two amplifiers regardless of configuration. Don't know how they will match up yet otherwise. in 1x350 mode it will be heavily attenuated.)
1x350 x 2 driving 10" HART series Subwoofers (0-80 hz).
So with this setup I would max out at 1700 or 1150 depending on the setup of the smaller subs. (Would be 1075 if I use 1 amp to drive both 6.5 subs at 2x75 but with the level of attenuation will be closer to 1400 than 1700 if I drive each with its own)
I am considering a dual battery system more for the CarPC than the system since I would seldom run the system much lower while parked. I do have an aftermarket WRANGLER alternator I may add to this system. This Alternator has an external regulator and is supposed to be 120amps hot or cold. It has dual outputs on it to power 2 batteries directly.
I know that GM has a secondary battery tray available for these trucks. I may consider a second battery just for the Sound system and PC and keep the main battery for the truck.
With a 2 battery system I was taught you really want to run with 2 identical batteries.
So what would you suggest here?
This truck comes with side "posts" and I normally don't like this setup because it can be hard to jump but GM was nice enough to have a remote jumping terminal that has a large easy to access post.
I realize the sale is likely over.. Just looking for information at this point.
