you won't be dissapointing with the Kolossus, awesome wire and won't look back if i had the money. As for the battery choice, look into the powermaster d3100 instead of tha SP1700. Far more reserve power and capacity. Do a search on those batteries, they are beneficial in daily systems and SPL events.
" I would put the new XS Power Group 34/78 D3400 with iBars under the hood. It will fit, as Powermaster adheres to group sizes in their larger batteries. The D3400 is good for 2500 watts as a primary battery and 4000 watts as a supplemental battery near the amps. ( given proper install, of course )
The Kinetik HC2400 is only good for 1700 watts primary, and 2600 watts supplemental and costs more than XS Power. The construction is all the difference.
Both XS Power and Kinetik will be easier to charge and keep charged. . so factory alt or not .. they are better than yellowtops.
If you still need more juice, the D925 is a great small supplemental battery near your amps. It's good for 2400 amp bursts / 2000 watts supplement.

Notice Alan Dante, Scottie Johnson, Steve Meade, and Tommy Mckinnie among many other win using Powermaster "
Apparently, the d3400 hasn't came out yet, so you will be pleased with the d3100.
