nitro229 Posted August 21, 2010 Author Report Share Posted August 21, 2010 The level 3s are rated at 600rms but I've been told that thy are underrated and can take more. And how do you figure out what the displacment is? And when you build a box does the whole box = 8 cubes with the port inside those 8 or do you add onto the 8 for the port?

bassl0va Posted August 21, 2010 Report Share Posted August 21, 2010 You haven't got the amp yet eh? might as well go for the 1.5k and give then 750 each. The subs displacement is probably only like 0.2-0.25 each. 8 cubes after displacement. so the port gets added on.

nitro229 Posted August 21, 2010 Author Report Share Posted August 21, 2010 Ohhh. Ok so totall would be more after the ports added on. And no I haven't got the amp yet, but what electrical things do I needa do to support that? Quote Link to comment Share on other sites More sharing options...
keepinitloud Posted August 21, 2010 Report Share Posted August 21, 2010 make sure you can get the box into the trunk if you build it outside of the car 8 cubes is a big box Quote 06 chrysler 300C Hemi one mmatts dreadnaut 15 powered by a planet audio vx 2200d fosgate p200 running planet audio 8" midbass drivers and super compression tweeters stock battery and a stinger spv44 Irragi 300 amp alternator big 3 1/0 http://www.stevemeadedesigns.com/board/topic/55075-system-in-my-300c/page__view__findpost__p__763656__fromsearch__1 Link to comment Share on other sites More sharing options...
bassl0va Posted August 21, 2010 Report Share Posted August 21, 2010 make sure you can get the box into the trunk if you build it outside of the car 8 cubes is a big box x2 on that. OP not that much more will be added, probably under one cube. And maybe an extra battery wouldn't need an alt though.

nitro229 Posted August 22, 2010 Author Report Share Posted August 22, 2010 Really? That's cool, and I'm pretty sure I could fit it inside if I built it outside of the trunk, but I would build it inside to be safe lol Quote Link to comment Share on other sites More sharing options...

Socky Posted August 22, 2010 Report Share Posted August 22, 2010 All you need is like a KHc1400, or a Xs power D5100, that should be fine for your sub amp and mids n highs.

nitro229 Posted August 22, 2010 Author Report Share Posted August 22, 2010 (edited) With a stock alt? Alright, and I assume wiring up the battary is as easy as it seems. Do you mean add a second battary or replace the stock, I guess adding a second would always be better right?

bassl0va Posted August 22, 2010 Report Share Posted August 22, 2010 (edited) You shouldn't need an alt. I've got a Atomic 3k and 80.2 running off a stock alt and semi upgraded battery. Soon to add a 50.4 to that as well. At the moment it doesn't drop below 12v with the engine running. But I really should get another batt. So I'm sure you will be fine. I'd add it on and keep the stock. Can't be anything bad about having that bit of extra power, make sure your alt can handle charging both though. But I'm sure it will be fine. \/ read what boon said in my sig.
