Usually, you can find a used US Amps USA-2000/2000x on ebay for about $500...that's a decent deal for a kick @ss amp.

I don't think you'll be able to fit 2 ported 12s in your supra. That's 4 cu ft plus port displacement. You'll have a pretty big box.

I like the Knuknoceptz Karma cables. They are easy to cut to length and work great.

That sub looks like it weights 70lbs. I like the polished basket.

Has anyone mounted their Sundown amps upside down? If so, were there any issues with heat?

It is for sale as of December 3rd, but we could arrange to do something sooner PM sent

Let me know if you want to sell you M5

Just a useful guide as far as port area.

There's only one way to get better! Plus, you'll be a lot more satisfied with the end result if you DIY it.

My house is 1800 sq ft 4 cubes is definitely doable...sounds like a plan. So if I go with 4 cu ft and (1) 80 sq in port, how long should the port be if I tune the box to 15 hz?

I've got 2000 watts to drive an RE XXX 12 - the split coil design. What would be the ideal enclosure size and tuning for a HT setup?

An SX is quite peaky and really doesn't excel at getting deep. They do get loud though. I've seen a lot of SX's used in a lot of SPL applications (aka Fart Box) tuned pretty high. I think an SSD is closer to an SE... balanced daily driver. If I had the choice and its deep bass that you want, I'd go for the Q hands down. A BL would be a good choice if you have more than 1000 watts to power 1 sub with.

I think you'll be okay but you can try using some polyfill. If you are going to cutout the bottom...why not just go with a custom FG box?

I think a BL would be a closer comparion to an SX than a Q. The Q will defintely sound better and will be about as loud as an SX.

Every car is different. Before you buy a 360.2...there might be more applicable alternatives if you are just replacing/adding the subs. If your car has an OEM sub, it might be more effective to use an SVEN2 off of the OEM sub leads. Not sure about the Audi's...might want to check with a local reputable shop or check out an Audi message board for info.

Quick question, how much does a Havoc 18 weigh?

I've had IDQs and currently have a Q. The only major difference is the Q is louder and requires/handles more power. The IDQs are very capable and great sounding subs. I'd stick with the IDQs if you don't care about being heard from a mile away. If you had not purchased the IDQs already, I'd suggest the Q. $259 for a Q12 vrs $300 for 2 IDQs...the Fi Q is a better value.

The NGT Extreme uses Absorptive Glass Mat (AGM) cells like the Kinetiks. For only $140, the carquest one is sure worth a try. Here is the thread: http://www.splbassx.com/forums/index.php?showtopic=9928

Yes...its all of the mods who are sealed box whores.

I love sealed...plan on going back to a sealed box myself. This forum seems to favor output and sealed boxes. I see a lot of sealed box setups on DIY Mobile Audio.

Alphasoniks have a reputation for being over-rated. Maybe try a different amp?

I've read that corporate owned stores should carry the complete line of carquest batteries. Not sure if the one you went to is corporate or franchised.

Carquest sells a rebadged battery labeled NGT Extreme. It uses the same AGM technology that Kinetic uses but costs $140 compared $400 for a Kinetic HC2400. Pretty good deal and lots of people swear by them.
