ok. so ive had people on here tell me that they have had thier battery in the trunk for years... and no problems... i just got the parts i needed and put it all together myself. and i only have one problem. it cranks slow. bad ground? or as my father and uncle said to long for the cables to transfer power... also, the people that have thiers done is it a dd?? cuz mine is. bad idea? should i move it back?

yeah you have to be careful with the grounds...make sure you grounded the engine to frame with real heavy wire too... that might help. were do you have it grounded now? mines a dd and it cranks fine...r u running the stock alt?

What size cable are you running to the starter and ground? Make sure all your connections are good. There will be more resistance in a longer cable, but it should not acceft it that much, something is wrong

yea the thicker the cable the better and the longer the more resistance. you will notice it starting slower. also how did you set of the distribution block? could have a bad connection from that or like u said could be weak ground

ummm where the trunk bolts to the body, i took off a nut stuck the ground there and bolted the nut back on haha. and im running stock alt. with 2 gauge wire, and it isnt hooked to the starter... its hooked to the solenoid switch. positive cable about 14ft. long and the negative cable about 2 ft. long. tell me what i need to do? im guessing someone is going to say get an altenator that puts out more amps... i want it all what everyone has to say? what should i do? i really want this in the trunk. thanks

I've put several battery's in trunks over the last 25+ years.
I always use '00' gauge welding cable, it has lots less resistance than any battery cable. Look at it and you'll see about 300 conductors (strands) in there, not just 10-20 like ordinary battery cables.
Welding supply houses can sell you the stuff by the foot and it never seems to wear out.........

it was my ground im prety sure, cuz i changed it up and car started no problem... ill see if it starts no problem tomorow and if it does, then i guess it was my ground haha. thanks everybody

Not to try n jack this thread. just curios to how u guys routed ur power wire from the the solenoid in the back "using quiks battery relocation method" to the starter up front so its not totally obvious??

I left my solenoid up front. Ran the positive cable thru the car from the solenoid to the trunk. Ground to the body in the trunk and also from the block to the frame.
