Several Questions about Subs

[fatboytyler]

Bear with me here, as I have a few questions...

Let me start with my amp specs: Rockford Fosgate R1200.1D (800 RMS @ 4 2 Ohm, 1200 RMS @ 1 Ohm)

I currently have 2 10" Dayton DCS255-4 (Roughly 200-250w RMS inside of the tubas) running in TAT Style Autotubas.

Notes: Due to size restraints I can not go more than dual 12s, so roughly a box that is 30" long. I also don't want to have to rob a bank to pay for new subs so I'd like to keep them at around $200 (preferably less) a piece. I have a 2000 Toyota Tundra Access Cab so my sound won't the best regardless because of limited cabin space, but I make due.

Questions:

1. What would make a worthwhile and noticeable upgrade? I have been looking at 12" Daytons that are 400W RMS @ 4 Ohms.

2. Would running my amp at 1 ohm be worth the extra heat and strain it'll encounter? I am all for this if getting 600 RMS out of 2 subs (or 1200 out of a single) would be significantly better.

3. Would getting a single large high output sub be better than dual 10"/12"? (In the limited cab size I have)

4. What are some of the quality (but not bank breakers) brands for subs? I have had incredible performance out of my current Daytons and have have 2 15" Daytons in my ancient home theater system and they are incredible speakers.

5. I would also like to put these new subs in a custom box, as long as the size is doable. I have seen these prebuilt boxes and they just seem too flimsy for me. I would rather do it myself out of quality wood and carpet it myself. What would be the steps in learning how to do this? Just use Google? Or are there some custom boxes designed around a specific set of sub combos you can all can recommend?

6. What exactly does a dual voice coil mean? For example, I saw a Dual 2 Ohm Voice Coil sub with an RMS rating of 600 Watts. How would I get 600W RMS out of this?

Thanks for bearing with me everyone!

EDIT: I know some of these questions are flirting with breaking the forums rules, but look at it as more of "In your Experience..." questions.

EDIT 2: I keep seeing Sound Qubed brand thrown around. I can get the HDS200 12" in 2 Ohm for a great price a piece, is this a brand that you guys can safely recommend?

a dual 2 ohm voice coil means you can wire your sub either for a 4 ohm load or a 1 ohm load

being that your amp is the R1200

that means you'd either be giving your sub 400 rms at 4 ohms, or 1200 rms at 1 ohm. If you're wanting to run a sub at 2 ohms, then you would need a dual 4

the SoundQubed subs are a great budget subwoofer aswell.

A pair of the HDS 200 would sound nice on that amp

More importantly you should explain precisely how much volume you have to work in, what your goals are, and what your budget is. Many people here think a few hundred dollars is entry level for a woofer worth using, some people would never pay more than 80$

Well my head unit is a JVC KW500 and I tend to try to keep my volume in the 24-28 (out of 50) range out of the sake of not overly abusing my door speakers (13 year old stock speakers. Either JL or JBL not sure). As I said previously, I would like to go no more than $200 a piece or less $400 if I went with a single larger sub.

@Dmac1991 thanks for the input. In your experience would 2 HDS200 (12") running at either 400 RMS (2 Ohm) or 600 RMS (4 Ohm) be a worthy upgrade?

Volume as in Cubic feet for your box.

If you're looking for a quality $200 12, go with an SA-12 from Sundown Audio. Their currently on sale for $155 for Black Friday/Cyber Monday

^Black Friday sale

I'm not sure how that amp would push them though. Might have to upgrade lol.

The SA-12s are rated for 600RMS each... and can take much more

If I were to install two subs with a shared chamber, should I double the Volume needed?
