XBSITE - The Definitive Source for the Scion xB

Just finished up a 4 hour install of my sub and amp. Since it was only 100 degrees outside, I'm not tired at all... Anyway, I'm not totally done with it yet. I put the sub in an enclosure under the passenger seat. The amp is in the back in the foam box next to the spare tire. I still need to modify that foam box so I can have all the wires completely hidden. I will also be installing a fan to help cool the amp as it got hot extremely fast.

Now that I know where to run everything, I'm sure it would take me a max of 1 1/2 hours to install the same setup again. Oh, and what a PIA the inline converter was to crimp into place. It came with the shortest wires, peckers.

I ran the wires the SMART way, so listen carefully everyone...
Power wires went down the left side of the car.
Sound wires went down the right side of the car.
They never came close to each other and that is how you prevent whine.

Overall, I'm very happy with my "boom" for the price of $67. I've got it setup so it's perfect at +3 bass, and when I don't want bass I can turn it down to -5. It can get pretty loud inside the car, and not loud outside. That is EXACTLY what I wanted. I just wanted to get the full spectrum and now I'm happy

Last but not least, I don't recommend using a drill to secure the sub to the box. It slips easily and creates a nice tear in the foam surround that is nicely covered up with duct tape

you got some pics?

you did it the right way
the other thing that will help prevent whine is a good set of RCA cables.

nice dude! glad you finally got all your components.... i have that that amp for you sitting here for months... either way glad youre happy

hmmmmmmm lucky mine is loud whever you and the car are 1/2 a mile away lol

can wait to see some pics! Congrats on the butt vibrator!

I'll take some pics soon. It's not really that exciting looking currently, and I didn't take any pics of the install because it's really self explanatory. This weekend I should have the foam box cut out so I can run the wires better and allow me to have it 100% hidden.

I'm all about the stock look when it comes to speakers.

Use 2 fans...one to pull air from the spare tire cubbie and the other to exhaust it out the other side, this will keep a good airflow.

Thumbs up on running the power/speaker wires. The factory wiring harness runs down the left side and the only thing on the right is the washer fluid tube for the rear.

congrats on your sound david

Peej, did you tie those fans directly into the amp for power? Just curious if it makes any noise through the sub.

YAY you have some boom boom in the trunk! I"m so happy for you! Once you get it, you can't live without it hahaha

I tied them into the remote wire coming to the amp. No, there is no whine whatsoever. The girl I did this for lives in Orlando and to my knowledge has never had a problem w/ overheating.
I got chastised on another forum from some audiophile for doing that. I can't remember his reason, but it tuned out that whatever he was all pissy about did't seem to be a problem for this set up.
BTW...those are 120mm computer fans and they move quite a bit of air

Thanks for the info Peej. Looks like fans are less than $10

what a cool idea!

Yeah I think I gave like $12 ea at best buy.

i don't think running them off the remote wire would ever cause a problem..... now running them off the main power wire to the amp it not a good idea, i tried it once and it didn't work out too well


i need a bit of boom myself.
i have some custom boxs i built to go under the seats with a set of comp 10"s i don't remember the brand. ive also got an old punch 800a2 amp that needs a little electrical work to get it going again.
im just being lazy i guess
