Ok, i got the 2 Adire Shivas and the Jbl bp600.1. Ive decided on going with a Large Sealed box, and i wanna build it myself. I still need a HU, but im trying to spend the least amount more on this and the box and installation. So would it be too hard to do the box and installation myself? (i have an intrudoctory knowledge with electrical stuff and carpentry.) And on the box, would quality of the box play a big role in how itll sound? And finnaly, im thinkin of going with a PIONEER PREMIER DEH-P560MP. could i get the options that HU has, or at least the ones that matter, at a cheaper price? (aorund $165 w/shipping)
For now ive got some 10 disk changer in my car, will i be able to set this all up using that until i get my new HU?

its not too hard to build a box by yourself, i did, with a mediocre knowledge of carpentry skills, although carpentry skills are needed, dont attempt it if your not familiar with the tools and skills, as far as quality of the box affecting sound? it has a huge effect on the sound, the box for the subs doesnt need to give at all, so the material you use is an important factor here. and if its sealed, it needs to be sealed good, when i built my box, i glued the wood with liquid nail, then screwed the wood together, then sealed it inside with some sealant. 3/4 inch mdf would probably be the best thing to go with here, as far as box building material, although im not entirely sure, I used 3/4 inch oak on my box, with internal braces, and it seems to be holding up fine under heavy bass, for around 5 months now, and its still together.
as far as the disk changer/ HU, youd be better off asking one of the golds.

sounds like you have the skills to build your own sealed box. quality of box plays a huge role in the sound you get so take alot of time in the design and materials used on the box. MDF(medium density fiber board) 3/4 inch thick is the best material. if the speaker side of the box is too large bumping up to 1" thick board on that side well help. also make sure its a air tight seal run a bead of silicon around the inside of the box at the seams so its a good seal.
and instaling an HU usualy is fiarly simple the first one always is a bit tricky but nothing we cant walk you threw.

Alright, im still looking at boxes though. And abouy using my current cd player, think it can be done?
uochronos on 10/13/2004 02:06:05
current cd player? you didnt mention what you currently have hehe. anyway though even if your cd player is stock it can be used however even a cheap pioneer, alpine, eclipse, jvc, sony, etc. aftermarket cd player well be vastly superior. although i would suggest at least a middle range one.

Im thinking of getting the PIONEER PREMIER DEH-P460MP for a HU. think that would work well with the Jbl bp600.1 and Shiva's?

any HU with a non fading(sub output) well work fine for your subs. really if the HU is set to flat no boosts on the amp and subs well sound pretty much the sameno matter what HU you use. the only thing that would change much is the preout voltage of the HU's.

thanks, but what is a non fading sub output?, and what do you mean "if the HU is set to flat no boosts on the amp and subs" and hwat will the preout voltage affect?

The rear of the deck you're looking at, the DEH-P4600MP, has two RCA outputs - which when fed to an amp would act as the front and rear channels. When you use the fade and balance controls on the HU, the amp adjusts the signals accordingly.
Some decks have three RCA outputs - one for the front speakers, one for the rear, and the last for the sub. The third RCA output would not affected by the HU fading/balance controls.
If you do not mess with the fade controls, you can hook the subs to the rear RCA outputs without sweating.

crum aniled what i meant by non fading.
as for the preout voltage. most amps gain range is sopmething like .2volt to 4volt but some have smaller ranges. you want a hu that falls into your HU's range because you want the amps gain to be set at the HU's preout volt. for instance if your HU has a preout voltage of 2 which is common then you would want to set your gain at 2 or slightly above it like 2.2volts.
