For amps I would look into brands like sundown, AQ, DC... thats just to name a few. For how much wattage, what I would do is add the RMS of each sub together, then add 500 per sub. So lets say they do 1500rms each.. thats 3k. Then add 1000 (500x2). That's 4k. So you'll need an amp (or amps) that can do 4k rms. The reason I add 1000 is because those subs can EASILY push an extra 500 rms each if you know what you're doing. You also want your amp to have some breathing room. So if you want to buy an even bigger amp, that would be even better. Mechman makes great alts as well as DC Power. You should do the big 3 in 0ga wire (which you can find a tutorial for here: http://www.stevemeadedesigns.com/board/topic/13280-how-to-do-the-big-3-tutorial/) After you do the big3, you can have your alternator installed by a shop or your dealership even... as long as you tell them to use the upgraded wire you should be fine. Then you need to start planning your enclosure size. When that's done, see how much room is left. Then start measuring the space for batteries. Put at least 2 or 3 supplimental batteries in. You will need lots of power to get those DD's to their full potential. You can do a lot with 5-6 grand. You came to the right place to save money and do it right.

Thanks joe! The way the measurements work, I'll be able to do both... I could use the same design and fire up or front. 412 CVX: How would you do the baffles?

ah, I see... Thank's again joe! I really do appreciate it.

Ah, thanks buddy! I really appreciate it! I'll have to post some pics for you when it's done Is it really gonna make a difference having that 3 1/4" peice in there? Just curious!

Thank you so much man! It looks really good! The extension you have written as 3 1/4 x 32 1/2. Is that a typo?

ya? ok because when I first built my box I had people telling me sub forward port sideways. But I think my biggest issue is size. I think I'm choking that poor Mayhem lol. I should have built a bigger box but I was trying to keep 4 seats in the tuck... How much port per square foot should I have?

I'm flexible. I can position the port up and sub up, or port front sub front. I don't want to fire back again because as it stands it does not sound as good as it could sound. As for rise, I don't know what its at right now.

Do you think I should build it bigger? Like 8cu or 10cu? I miss my honda.. was so easy to be loud.

Hello everyone, I have a 4-door F150 and I'm looking to design a box that would sound good in the back seat. My sub is an 18" ascendant audio mayhem. Currently I have a 5.5cu/ft box behind the passenger seat. Sub forward port back. It just doesn't sound right... Not loud enough (compared to my 15" fi btl that I had... still a bit louder but not by much at all). I think the box is too small. I was just wondering if anyone had experience building boxes for trucks or would like to help me design a box that would be very efficient for my application. I have posted my max dimensions, amp rating and my sub's T/S specs. Thiele-Small Parameters 18" Coils Dual 1 Ω / Dual 2 Ω Re 0.7 Ω / 1.4 Ω Fs 33.7 Hz / 33.2 Hz Qms 6.52 / 6.62 Qes 0.29 / 0.27 Qts 0.28 / 0.26 Mms 307 g / 317 g Sd 1210 cm^2 Vas 148.9 l SPL 94.8 / 94.9 1W/1m Bl 17.7 / 26.2 Tesla Meters Xmax 30mm (one-way) RMS 2500w Amp specs: (I am running my sub at 1ohm) RMS Power @ 4 ohms 850 watts x 1 channel RMS Power @ 2 ohms 1700 watts x 1 channel RMS Power @ 1 ohm 2600 watts x 1 channel Bridged RMS Power N/A Peak Power Output N/A In reality I'm probably seeing closer to 2k rms unclipped power. Max dimensions: 34H x 35.5W x 20.5D (D is for depth from front to back of the box) Thanks in advance for anyone who wants to help me... I'll also post a build log as I do this next one.

Can you elaborate on that?

Well technically hes not local. He's across the country

What if you hook em up in parallel? Same thing? Still ok?

Price on a DC 3.5K and DC 5.0K to ontario, canada k4b 1t4. Canadian dealer charging too much I think.... We canadians get raped here. If anyone wants my business plz quote me.

Is that true? I was under the impression that 2 different batts = fail

what was it?

From what I understand, OA and SA have an affiliation somehow. (I may be wrong)

I'll post the youtube vid when I get home! You'll see I'm not crazy!!! haha

Try some scratch remover. It does work for light scratches. Mothers sells it I do believe as well as meguiar's. Take that stuff, a terry cloth and an hour. Buf the shit out of it. Then wax over it. Should help a lot.

I played with it about 6 months ago. They'll have to trash it and start over with the GUI. It's bad atm IMO.

Nope it was a drill bit with steel wool looking stuff around it... was about a half inch in diameter. And it can be used straight onto the surface, not on an angle.

I was wondering if anyone knew of a drill bit that can be used to grind down the paint for a ground? I'm looking to make circular clean grinds to the frame. I saw steve use one in one of his youtube vids when he was installing HID's on his F150. I've been looking for a few days now and I can not find it anywhere!

My first amp was a Bazooka 250. This amp had an option to be water cooled. I had it installed by a professional car audio shop..... they had the gain at MAX because they thought it was a volume knob. Bass boost was on. Bridged to 1 ohm (even though it was 2 ohm stable). You could cook eggs on that thing it got so hot. It never died.. I miss quality of the older gear.

x2, I love sonic, Now where's that coupon code? I'm about to order around $500 worth of stuff lol Same! I needs me 50' of 0ga!!

Welcome sonic! You guys are my favorite place to shop!
