Ho alt or extra batt?

I'd also be willing to say that what his whole system cost was less than just a single 5k DC or Ab amp that everyone runs against him hahaha

at idle expect more drop then that.

I will lol. Not going full tilt unless I'm driving.

You really need to get on a meter when your done and see what you can hit. It would be nice to see some new people in the rookie 1 and woofer cooker 1 class

I probably will end up getting metered lol

i had pretty much the same setup as you, and driving voltage wouldnt go below 13.5 at idle it would drop down into the 11s at full tilt.

Yeah the only time I would be goin full tilt at idle is at stop lights. And even then I turn it down cause I'm not one of those douches

Alt.. It will maintain more power over a longer time

Depending on what it's used for though, it might not be a worry. Doing SPL comps and running burps, not so much.

both

I've been running a 3k amp on a stock 105 amp alt for a couple years with no issues, I did upgrade the batteries though and did the Big 3. Two XS Power batts. If you plan to keep the 2K for awhile save yourself the money and buy a real battery, or two, and skip the HO Alt til you decide to upgrade.

Have a dc 2.0k coming and current stock batt in the trunk. Upgrading big 3 in a few days. Question is should I go with a 270 amp ho alt from Mechman for 349 plus shipping or do you guys think an extra batt will hold my voltage up just fine? Stock alt is 130 amp I believe.

i my self was running 2k from a stock 100a alt with 2 extra batts and my voltage maintained pretty good, 90% of time it stayed 12.6 - 12.8. how ever im a cheap mofo lol. if u have the money for the HO alt id get it. it will benefit more in the long run. i finally broke down and got a 220 HO alt for mine system.

no 12v battery bank will maintain 14.4 for long if your volume heavy. Once they are drained down they will keep draining.

I dont see this as good voltage. On a 2K amp you are losing a ton of power

sorry i should have been more specific. the 12.6 - 12.8 was at idle. at 2k rpms it stayed 13.2 - 13.5 depending on the song played. yea i know i probly lost power from the amp. but for OP if hes not competing thats not bad daily voltage.
