After a little research. I decided I wanna throw a 10" Orion XTR in the front half of the spare tire location and am gonna power it with a jbl gt500.1 amp I already had. Built a 1.15 sealed enclosure, and am gonna install this weekend when the rain stops. My thoughts are too disconnect beats sub, use the two sets of speaker +|- that connect to it and connected my Rockford Fosgate 2-channel line out converter to it for my amp signal. Only question I have is the closest amp remote turn-on wire. I can only assume there is one coming off the factory amp. Then I never have to mess with the dash. Thoughts?
I do not have the beats set up, but I did install a pair of 10" subwoofers in the spare tire area. I tapped into the rear cigarette lighter to get the power for my line out converter (AudioControl LC2iB). Then I tapped into the rear speaker wires to get the signal. With that converter hooked up properly, when there is a signal from the speaker, it turns on the amp/s. I used an Alpine MRV-M500 to power the subs. Later on, I hooked a pair of Infinity Kappa 6x9's to another two-channel amp using that same converter. Everything but the 6x9's is tucked away where the spare tire would be.
Sorry it took so long to get these in here. My set up is ugly, but I think function over form. The first picture shows where I hooked the 4-gauge wire to the battery. I then ran it up the corner of the hood and into the body as you see using the grommet already there. What you can't see is behind the plastic area. I wish that I had taken all these pictures as I was building it, however, it was hot outside and I just wanted to finish it. I had to drill a hole and figure out how to push the wire through. I then ran it under the plastic and through to the back seat. I did lose quite a few plastic clips in the process and had to replace them. I then put dynamat all along the inside of the spare tire area so the sound wouldn't vibrate so much. I found the perfect sized box to fit by measuring and researching through the internet. Once I found the perfect sized box, then I chose the speakers that fit properly in that size.
In these pictures you can see the line-output converter (that is hooked up to the cigarette lighter), subs, amplifiers, and capacitor. I wired the 4 gauge to the capacitor and wired a 4 gauge to the Alpine sub amp as well as an 8 gauge from the capacitor to the Blaupunct amp. I tapped into the rear speaker wires. That was one of the hardest parts. I have included the colored diagram I found on the internet to tap into the correct wires (be advised that the rear speaker wires are orange, not yellow as it seems in the diagram). I used Posi-Products™ Wire Connectors from Crutchfield for all my taps. They work fantastic! The line-output converter adjusts the bass since most cars will automatically lower the bass output as the volume goes up.
The amps and line-output converter are each rubber-mounted to a piece of wood that I cut to fit into the wheel well. I also soldered the speakers inside the boxes so that vibration wouldn't make the wires disconnect (I had to because that happened twice before I did). The final pictures here you can see that all of it is nicely tucked away out of sight. I didn't really like the sound I was getting from the stock rear speakers. I also wanted a set up that I could have at the beach or a party where I could turn the speakers around or put them on top the car to crank up the sounds.
