I put a another battery in my trunk. I just want to make sure I did it correctly. I piggy-backed the positive off of the positive in the engine compartment and grounded it to the frame in the trunk. To ground the amps I took three six foot long 10 gauge wires per amp to make 3.3 gauge wire and grounded them to the battery in the trunk. I know this is kind of overkill for the amount of watts my amps are pulling, but I'm all set up for an amp upgrade in the future, and since I heard on the news earlier this week that the 92 accord is the most stolen vehicle in the nation, it will be a great place to power my alarm, once I purchase one. The strange thing is that everything is brighter. My tail lights, my headlights (even though they are only 35 watt HID lamps), and especially my after market running lights that I mounted on the bottom lip of my bumper. They are 6" long and 1" tall and have eight or so bright white LED lights in them. I just hope I did this correctly and I'm not going to fry my wiring harness. My engine even seems to like the extra juice, or it could just be my twisted mind, like when your car seems to run better after a nice wash and wax job. I don't know. Anyway, thanks in advance to all who respond to this. Fly.

dont think the grounds in the trunk are good, my cousin relocated his battery to the trunk and it kept draining out and it was one of those yellow top

Ok I have a question for u, u said that u took 3 6foot 10gauge wire for the grounds of the amps ok. But what kind of wire did u used to conect both bateries? What size of wire u ran from the front battery to the back?

that dont matter. the metal in the trunk is the same as the engine bay. your cuz might have had a bad battery or a short. hell he couldve even not sanded down the grounding point like your suppose to. all that can affect start ups & more.Originally posted by JaberCB7 View Post

I hate that when people say the 92 accord is stolen so much, yet they neglect to mention that the 92 accord is one of the most common cars in America. I'll bet if you drive around any city you'll see about a dozen 92 accords before you reach 7 of anything else. Unless you pass a car dealership. They don't count
. They need a theft per capita number, that'd be so much nicer.
Anyway, don't try splicing 3 wires together to make one good wire, it tends to be really messy and complicate stuff. There's almost no way that your amp's terminals are clamping down all 3 wires very well, if one of them comes loose and manages to slide over to the positive terminal on your amp it won't be pretty.
What wire did you use to go from the front to the back? And from the battery to the ground? If you're using those short sections of "3.3" gauge wire but you're running an 8 gauge positive, those grounds are being restricted by the positive wire. Also, what wires are going from which batteries to which amps?
Just do like me, run a 0 gauge positive from the alternator to the trunk battery, a 0 gauge ground from the trunk battery to the trunk frame, a 0 gauge ground from the trunk battery to the engine block, and a 0 gauge ground from the engine to the frame. Then some good single wire grounds from the battery to the amps.Comment

Thats the best bet, 0 gauge from front to back and battery to battery, then use at least 4 gauge to the amps, if you can use the 0 gauge also for the amps even better.Originally posted by Sarthos View PostI hate that when people say the 92 accord is stolen so much, yet they neglect to mention that the 92 accord is one of the most common cars in America.

I run 4 gauge to a 300 watt amp, it's just plain better wire
And the reason that you might notice a bit better performance and such is that your car is running at a slightly higher voltage, therefore you're getting better spark, better power to your lights, etc. It's probably also taxing your alt a bit though.Comment

what gauge wire did I use for battery in trunk.
I used 4 gauge wire from the battery under the hood to the one in the trunk. Then I used 4 gauge wire to a Y adapter and ran 8 gauge wire to each amp, so I guess you could say that I used 3.3 gauge wire to ground each amp (since 10/3= 3.3) to the battery and the final ground from the battery to the frame is 2 gauge wire.Originally posted by masterbarber View PostComment

Wow, I guess I am going to have to invest in some serious wire upgrade. My amps aren't very high wattage, and I'm running the amps off of the battery in the back. I only used the 3 pieces of 10 gauge to ground my amps. All my positive wiring is solid and I crimped the ends of the grounding wires so I think they are making a good connection.Originally posted by Sarthos View PostI hate that when people say the 92 accord is stolen so much, yet they neglect to mention that the 92 accord is one of the most common cars in America.

Look the right way to do it is to buy a voltage regulator....Which you run a wire from your altenator to the regulator then to your Batterie then to your Cap then to your amps......4gauge wire is fine.....Thats the right way to run a second batterie....But if you think you can just jig rig it and run a wire from you first batterie to your cap and then amps....No matter what you should get a cap cause you say your amps isnt all that so instead of doing all this I would try a cap out first....Cause I HAVE 2 amps and 2 15's in mine And my lights dosen't even blink or my wideband doesn't even lean anymore then it should meaning its not putting strain on the batt or altenatorLast edited by WhiteGhost; 10-11-2010, 04:35 AM.Only give advice when I know or have done it and it worked
