This weekend I installed two Infinity Kappa Perfect 10.1 and a Polk Momo 500.1. I still need to make a false floor to cover the amp and I need to make some custom speaker grills or buy some nice ones. I took pictures step by step. Tell me what you think.

Here you can see how I built the box.

More about the box. You can also see the line converter I installed.

The finished boxes and the start of the amp install.

Test fit of the boxes and amp install. If you look close you can see that the cap, amp, and tire kit are mounted on 1/4" plexi glass.

The finished product! It still needs a little fine tuning but it is almost done. I think I am going to make the sub grills look like rotors. Any ideas on a false floor?

excellent!! Very slick indeed. I wonder how long before ppl start requesting boxes? :D

FYI- the boxes are 0.61 cubic feet. Infinity recommends 0.6 cubic feet for the Kappa Perfect 10.1

hey RR what is going on with the battery compratment and that switch (I'm assuming sub power...something something)

don't mind me I know LITTLE about car audio

I installed a 40 amp circuit breaker in the battery compratment. I thought it would be better then a fuse because I could reset it for free (rather then replacing fuses)...or just use it as a on/off switch when someone else drives my car.

any reason in particular you used 5 ply pine instead of MDF? That's just strange to use plywood...i don't know if i need to go into why here, i don't want to insult your intelligence...i've just been in car stereo for quite some time (13+ years)...

MrWigggles

Grade A plywood is probably the best inexpensive material you can use for box building.

The best strength to weight ratio wood is generally considered to be birch plywood. This is the what is used in the very expensive B&W speakers. It is an excellent choice for a sub enclosure.

Quality plywood is an excellent choice for sub enclosures and from the pictures it appears that Rasp used just that.

(Ps. I use MDF myself because it is more workable and cheaper; but that doesn't make it better.)

Looks good... too good... must resist temptation to install aftermarket audio in 8 as I said I would... pain... ahhhh

Yes, I used 6 ply plywood because it is much stronger, however, it is harder to work with. The last box I built I used MDF and i considered it a single use box because once you remove the speakers screws from the wood. Well, you can't really put them back in the same holes... (the wood isn't strong enough). so you have to drill new ones and seal up the old ones. I used 3/4" 6 ply top grade plywood, glue, silicone, and polyfill on this new box. With all the angles the box has...i can say it is real strong.

yo gotta say that does look RUDE, at first i thought the amp was a nitrous bottle, then looked closer and now it looks like a time bomb crossed with a nitrous bottle just kidding but nice fit with the 10's, do they sound any good ?

The subs it hard, hard enough to take the air out of my lungs and make me see things. I am seriously worried about blowing the rear 6x9 speakers because the amount of air the subs push. Is this a potential problem?

XDEEDUBBX

thats a nice install..really clean without sacrifising space..

mr2000x

no i dont think u can blow them just from the air but dont quote me, are they the stock 6x9's?

Rotary Rasp

iTrader: (2)

yes, stock 6x9 bose speakers

mr2000x

i asked a dealer once about changing the stock 6x9's for a pair of alpines, he said they would sound so much better than he stock 6x9's even with the same amp, did u chang the amp for the rest of the system?

Rotary Rasp

No, I havne't touched the bose system. But I want to replace the speakers with Infinity Kappa's. 6x9 in the rear and 6 1/2 in the front. I am worried about destroying the bose amp by hook non-bose speakers to them. If the amps are made to run at 1 or 3 ohms, hooking a 4 ohm speaker may destroy them.

XeRo

You're correct in void free birch ply, and I wasn't stating MDF is better...but comparatively speaking between PINE ply and MDF it IS better...you have more weight, yes, with MDF but you have a more dense box...pine ply is very prone to shattering amonst ply's especially when used as a sub enclosure. Now void free birch if you wanna pay the pretty price for a sheet is by my standards and tastes the best suited and sounds exquisite (sp?) as an enclosure...I have done custom enclosures using birch in several BMW and Mercedes cars, with inset pieces of zebra wood and other exotic woods, stained and high gloss poly to make for 'pimped' out rides and they always sounded better than any MDF box...that's all beside the point, I was just wondering if he might have been led astray on using PINE...that's all..

no biggy..

SlashMatrix

Nice choice. Go with the infinity kappa perfect series components if you are willing to dish out the cash. They are awesome. I'm not sure if they have 6x9s though but it would be something to look into. My brother had kappa perfects all around in his montero sport and 2 12" IKP subs. All i had to say was wow. Almost as loud as my diamon TDX :D But very nice install. You could even mount a PS2 between the subs if they don't hit hard enough to make it skip every 5 seconds. probably will though

I get a huge discount on Infinity products, so i'm installing only their best stuff. But I still need to know if hooking 4 ohm speakers to the Bose amp will hurt them. How many ohms are the Bose speakers, how many watts RMS?

MrWigggles

The rear deck Bose speakers are 2 ohms. 4 ohms should be no problem at all but will play about 3 dB lower in output than the Bose that are already there.

Keep that in mind. Good luck.
