The 2 ohms is for the subs. Twice the power= twice the bass.....

 

ok I get yeah now .

 

Here are some amps that would work for you. I recommend you PM PAs2kNUT and get the amp rack from him (replaces the spare tire).....A good 4 channel amp is NOT small.

The types of amps you are looking for are these....

You get the idea.

 

all of these amps look good and in your price range.

 

I just went through the process of installing a system and really struggled with where to put the amps. I have a JL 300/4 for the cabin speakers, and a JL 250/1 for the sub. After scratching my head for days I finally conceded to mount them in the spare tire area. Being a experienced woodworker I made my own rack that allowed me to mount both amps on a single plane, as low as possible to give plenty of room for heat dissapation. I also "vented" the rack under the heat sinks on the amp to allow more air flow over them. I really wanted to mount at least one of the amps under the passenger seat but I really saw no way to make it happen with a decent amp. For some reason the majority of the amp market has taken on the bigger is better attitude. I think this is more of a consumer demand thing as large scale intergration of electronics could easily cut the circuitry size, heat would still be an issue though.

So now my only issue is not having a spare tire. I think I can throw the temp in the tool well for long trips, around town I am not that concerned.

I do have to give big props to Wlaurent. I'm running a single 8" in a drivers side box and it absolutely rocks. I was initially concerned that an 8" wouldn't cut it but it works perferct for our listening tastes.

 

I don't understand the aversion to regulated power supplies in car amps?

Given that a car is typically subjected to many different operating situations, regulated power supplies are an advantage. Now, for all-out SPL where there are HO alternators, extra batteries and the need for short bursts of power at the rail, sure unregulated is a benefit. Sounds like for this install something with a reg. power supply would be good, especially since the S2000 has a fairly weak alternator and battery.

My recommentadion is off the beaten path, but a Zed Audio Draconia would be my first pick. First, Zed has an impeccable reputation and has made countless amps for some of your favorite brands(HiFonics, ESX, Autotek, 1st run Planet Audio, and USAcoustics, to name a few). Their older designs reign supreme, even today!

Second, the Draconia will do 70watts into 4 channels on a 4 ohm load 12.5v! It's only regulated on the "bottom" and benches 90watts per channel at 14v on the same 4 ohm load. In addition, it has 2 ohm ratings of 140 watts into 4 channels at a 2 ohm load. Also, it has fully adjustable 24db/slope Butterworth crossovers onboard. Typical current consumption with music is an easy on the alternator: 12 amps.

I doubt it will fit under the seat, but at 17" long, you could mount it against the rear bulkhead and it would probably be fine. The cooling fin area is substantial and I doubt it would punk out on you from heat. This will beat the crap out of 2 10's and those Infinity Perfects..

Well I did some more research and I think I'll be going with a good 2ch amp and then a D class amp for the subs.

 

Simple, your dollar per watt ratio is much lower. A regulated power supply will give you the same amount of power, regardless the ohms. An amp without one will give you two times the power, if the ohms are halved. The s2000 is a car that needs power, not clarity. When you need high end amps for a car like....say....a Lexus LS430, you can get a much better amp, again, without a regulated power supply. (Audison, Brax, Helix, Tru, etc) I dont see the benefit on a regulated supply. The amp will put out a bit less power when the car is off, so what....you listen to music 99% of time with the car on, at 14.4 volts.

They are not BAD, IMHO, they are just not worth it.

 

Not really necessary, and youll probably spend more money than 1 good 4 channel. Any of the above amps posted will sort you out very well. Also, a good A/B 4 channel can be used for a heap of applications, while class D are only for subs.

However, good luck in whatever you decide.

 

OP - There is probably little reason for you to go with two amps. You will probably have to spend more and it will be harder to install and run cables and wires. I suppose you're concerned about power output, since you seem to want a very powerful amp. Others here can help you more if you give some more info into exactly what you want. In a little car like an S, you may not need as much power as you think you do.
