This is a two part question. First part, I want to install two 10" subs in the trunk one on each side. Can someone who has done this please help me with a diagram of the installation. I was told the only way was to custom fiberglass. I do not have the money to get this done or the know how to do it myself. A diagram would be greatly appreciated. Ok on to part two. I would also like to know the optimal way to set up a two amp system, once again a wireing diagram would be awesome. I have a small amp to run the componets in the front and a bigger two channel amp in the back for the subs. Any and all information and diagrams would be very very appreciated.

Alright... I guess I'll help

1. If you take a look at this threadhere, it should pretty much tell you everything you need to know about making a fiberglass box. They are just about all made in the same basic fashion so if you can do one you can do another.

2. Now this question kinda makes me a little nervous... So before I answer it, I'm I correct if I assume you've never installed an Amp before?

 

well kind of correct I have installed several amps in my cars before, but never a two amp system. i was just wondering if there was anything that different from a normal set up:


Power from the Bat to both amps

ground them to a good source


secure them in a place where there is good air flow

connect all applicable wires


I just wanted to know if there was anything I should watch out for I guess.

 

Nope just make sure you use the right size power lead, and ground leads. Make sure you have the proper size fuse for the power lead to coverboth amps. You can even add a secondary fuse in the trunk but you don't have to. Ground the amps to the closest point. The grounds should be the same size or down sized to the next wire size down. I run a downsized ground on my personal setup.

 

DK,
When you say "down", do you mean AWG, or actual physical size?

 

Yes downsize the wire size in AWG

 

Thanks, for the info. I'm not at car wiring illiterate as you may think I just wanted to make sure there wasn't anything that I was forgetting. Plus about the boxes. You make the custom fiberglass work sound easy, but for a first timer like me it still is pretty intimidating, so I think I will try to do a custom wood box so how, thanks for the info. If you have anymore please shoot it my way.

 

Just keep in mind that fiberglass isn't really that hard. I know it looks like it is, but its not.
But it does sound like your new at building boxes which is totally fine, and you should start with an MDF box first. If that goes really easy then give the FG a try.

 

yeah yoru correct with that statement, I mostly have used pre fab boxes and MDF boxes I made. I will try FG soon, and let you guys know what happens
