I own a 2009 Chevy Traverse. Which battery application do you reccommend for my car? Second should I upgrade my stock alternator to a high output alternator? Im going to be running a precision power amp max watts are 2600 hooked up with a one 15" JBL .
I will also be running a double din in the truck as well. The biggest thing is if the battery will fit in my vehicals location.
Tommy on Apr 16, 2015
Best Answer: Hello Thomas,

Your vehicle's BCI group is 48, which means the D3400 will fit within those dimensions. In regards to your setup, you didn't provide very much useful information, but we can say that the upgraded battery is likely all that is needed. "2600w Max" likely means you are running At Most ~1300w RMS, IF we assume you are running the amplifier at its lowest impedance. At ~1300w RMS, most vehicles hold up just fine, especially a truck/suv . Nevertheless, the vehicle AND system will benefit from a proper power reserve, so the D3400 is a Great addition. Moreover, instead of a HO Alternator , we suggest investing in the BIG 3 Upgrade instead. Its far less expensive than an Alternator, and will benefit your application far more.

For future inquires, please provide Model Numbers, not a description.

I own a 1998 Lexus ES 300. I need to know what XS battery application do you recommend for my car? (2 Do you recommend that I upgrade to a high output alternator from the stock alternator that's currently in my car? (3 what Big 3 upgrade kit do you recommend should the upgrades be needed? (4 The system I plan on installing will be a 5 channel NVX JAD 900.1 amp drive 4 door speakers and an 8 inch subwoofer!
Jamal J on Oct 10, 2014
Best Answer: Hello Jamal,

You have chosen a VERY efficient amp- NVX JAD 900.1 - that will not require a very dramatic upgrade of your electrical system. You will NOT need a HO Alt; One is often required when getting outside of the 2k-3k RMS range, and you are safely hovering around ~1k . We do, however, suggest AT LEAST the Big 3 Upgrade and CONSIDER a better primary Battery. The Big 3 is an easy setup, and the NVX XBG3PK is the most practical. In regards to the battery, the XS Power D3400 will be the Most practical. It definitely will provide you with far better figures than you need, but it sets you up to run the setup in optimal conditions, and will also allow you to upgrade in the future. Your vehicle has a strange BCI group, so there is no 'perfect fit', but the XS Power D3400 fits well within the dimensions available.
