IH8PunkRok Posted November 16, 2007 Report Share Posted November 16, 2007 So, I was talking to a friend and asked him how he would wire the amp to the battery. He said that there should already be power cables that I should splice the amp power into. He also said that if I ran the amp power directly through the firewall and into the engine compartment, where the battery is, the wiring would burn. Is any of this true?Thanks. never listen to him again a separate power wire for the amp is a must splicing should only be used as a last resort IMO especially on a power wire Quote -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
Torres Posted November 16, 2007 Report Share Posted November 16, 2007 (edited) actually i would NEVER splice into anything for a power wire for an amp. not big enough, and just better to have it's own power. i drilled through my own firewall and ran like 8 wires through it. not one fire. no reason for there to ever be a fire. so yeah...dont listen to him again hook it straight up to the battery. if you need i can take pics of mine and show you how i ran it and how it's all done Edited November 16, 2007 by ExpoSport Quote Link to comment Share on other sites More sharing options...
Derrick824 Posted November 16, 2007 Report Share Posted November 16, 2007 Connect your power wire directly to the positive battery terminal and make sure to fuse it. Absolutely do not splice it anywhere. Running through the firewall is fine but make sure to use a grommet. If the wire rubs on bare metal then the shielding can schafe and rub through which is bad.

THanson Posted November 16, 2007 Author Report Share Posted November 16, 2007 Alright, that works. So, just drill through the firewall and use an o-ring to connect the power directly to the battery terminals? Sounds doable (hopefully).

roscoe1129 Posted November 16, 2007 Report Share Posted November 16, 2007 Hansen take a look in the build section or click the link in my sig and you will see how I hooked my power wire up to my battery. The OLD amps some used to have a wire hard wired into the amps but they dont do that any more all amos have a connection for the power wire, ground wire and remote wire.

Torres Posted November 16, 2007 Report Share Posted November 16, 2007 just check and double check where you're gonna drill. just to make sure it's empty space on the other side. and also you wont need any kind of connector to go into the amp. it'll just take the bare wire. but for the battery, you'll need some type of connector. depends on the battery Quote Link to comment Share on other sites More sharing options...
THanson Posted November 20, 2007 Author Report Share Posted November 20, 2007 So, I bought the subs and amp and all that jazz tonight. As I was looking at the diagram for my head unit, I saw that there is this cable call Subwoofer Output. It looks like a white RCA cable. There is no red mate to it or anything. On the actual amp, there are red/white RCAs labeled input and red/white RCAs labled output. What do I plug into the "Subwoofer Output" cable? My understanding of what it does is that it controls the level and such of the subs from the head unit. Thanks an asston, y'all. Quote Link to comment Share on other sites More sharing options...
roscoe1129 Posted November 20, 2007 Report Share Posted November 20, 2007 you can get a single to double rca Y adapter from the shops to hook your sub output to and then you hook your rca's to the adapter then to the inputs on the amp.

THanson Posted November 21, 2007 Author Report Share Posted November 21, 2007 (edited) As of November 27, the subs are in. I would post pictures, but the set-up is kinda boring. Nothing spectacular. Thanks for all your help, people of SMD forums. Edited November 28, 2007 by THanson Quote Link to comment Share on other sites More sharing options...
