I currently have a Optima yellow top under my hood and XS 5100 in my trunk, was looking into buying a XS 3400 to replace the Optima looking for opinions. System consists of Iraggi 300 amp alt, one Crescendo 3kwp and a Crescendo 1000c4 along with two DC LVL 4 15's with d.7 coils.

Are you asking if the XS D3400 will be a better battery for you than the Optima?

XS Power is superior.

No I know that XS is a better battery than Optima thats why i'm switching it out, what i'm wondering is will the 3400 be o.k. under the hood or should i look into another model for that application.

it will work fine under the hood in the stock location

O.k. thanks.

What kind of car do you have? XS power may have an exact replacement.

07 Impala ls.

You have a group size 34 battery. That D3400 is perfect for your car.

Thank you for your help.

Yes the 3400 will work for you and if you are running side posts look at the 551 or 555 iBar kits.

thanks Nathan, i do have one more question would the 5100 i have be o.k. to run along with to Deka group 31's? someone just offered me a good deal on a pair but don't want to ruin my 5100.
