looking to do alittle sytem in my 2007.

So far was looking at 12in http://cgi.ebay.com/ebaymotors/2000-Honda-...rsQ5fEnclosures

Alpine SWR-1222D http://www.crutchfield.com/p_500SWR1222/Al...22D.html?tp=111

Alpine MRP-F250 http://www.crutchfield.com/p_500MRPF250/Al...html?o=n&tp=115

Polk Audio db651s right Size ?? http://www.crutchfield.com/g_400/All-Car-S...html?o=n&tp=105

On the subs should I do a Dual 2-ohm voice coils or a 4? Also do I need a four channel and another 1 channel for the sub? Will those parts fit in the s2000? They good brands?

 

Depending on how many speakers you're hooking up, if it's only 2, then a 2 channel will suffice. If it's four, then go with a 4 channel. If you're hooking up tweeters (I believe for Polk it's DB6500, but don't quote me on that) they come with a cross over, so a 2 channel is still fine for that, though you can still go with a 4 channel depending on the tuning capabilities of the amp.

As far as between 2 and 4 ohm, it's going to depend on the amp first off; you'll need an amp that is 2 ohm stable if you go that route.

Low impedance or resistance of 2 ohms connected to the amplifier allows more voltage and current to pass through the load. This increases the power rating at the cost of sound quality. In addition, the damping factor (the ratio of the internal output impedance of the amplifier to the load presented) of the amplifier is usually cut in half.

With higher impedance such as 4 Ohms, you'll find that bass definition and detail is much better. The affect on the vehicles charge system is also greatly reduced.

In short: 2ohm=louder hard hitting power 4ohm=better bass definition, less power consumption.

It's going to depend on how you want your system to sound that will determine whats best for you.

I also suggest getting a Class D Mono amp that is capable of pushing an Alpine Type-R if you decide to get that. 800w RMS at the very least.

Oh, and yes, those polks are the right size. The "s" at the end indicates "shallow mount" which you want, because most polk magnets are large and are considered "oversized" much like the Infinity Reference series.

Good luck!

 

im doing two speakers bec, that's how many are in the car right??? Then 1 12in sub. Are there tweeters already in the car??? If all is right. How many amps do I need? Just one Four ch amp to power everything?

ALSO GREAT READ.. THANK YOU VERY MUCH. Anything else I might need? Also anything better then the Alpine Type-R sub?

Are the parts anygood I listed?

 

Yes, there are only two speakers, though you COULD power the tweeters off the 4 channel, if you get component speakers; though I would just hook it up to the crossover that they come with.

You would need a 2-channel amp and a mono sub-amp for what it sounds like you want to do. You could use the 4-channel to power everything, but I think you'll be under powering the sub. That, and A/B class amplifiers will have a tendency to over heat if you put too much load on them.

Nothing wrong with the setup that you listed, but like most everything there is ALWAYS something better. How much money you spend is just going to depend on what kind of system you want to build.

What you're looking at right now is a very decent set up with good bass and clear mid to high range.

As far as if there are already tweeters in the car--yes there are factory tweeters, though you may want to replace them with a component set; it'll sound better.

 

So I need just a good power 4ch amp right? One to power the sub and the other two to power the speakers right? Then the two tweeters.

 

I mean if you want to, you can run it all off a 4ch, but I don't recommend it.

Like I said: one 2-channel for your fronts and 1 mono d-class for your sub. It'll sound better that way and stress the amp way less.

If you get a four channel, use two channels for the front and you can bridge the other two.

 

Can you post some really good amps models ?? Also do they make tweeters that fit right in? If so can you post that also .. Thank youuu.

 

I cannot honestly tell you what will work best for you because I don't know what kind of system you're trying to achieve here. It's going to be up to you to do the research based on the information given; I can't pick something out for you because you might not like it. That's the problem with car audio.

People say "what speakers sound good?" etc, but I can't tell you what sounds good to you. We all have different tastes and hearing, so the only thing I can suggest is to go find out what is best for you. Research!

Good luck.

 

your 100% right. Also I tried too see of they make tweeters that fit right in. Can't find anything. anyone have them in there s2000?

ThANKSS

 

You'll have to find 3/4" tweeters to get them to fit without any work. Most 1" tweeters will fit, but you'll have to dremel (carefully so you don't damage the actual tweeter) the outside plastic casing for the mounting posts. The Polk db651's do have a 3/4" tweeter, so there shouldn't be any modifications required.


As for subs, I highly HIGHLY recommend the Stereo Integrity Mag 12". $250 shipped, and it will absolutely blow that Alpine 12" out of the water in terms of sound quality and output. www.stereointegrity.com

The Polks will be ok. I'd recommend putting more $$$ into the speakers though. Realistically, your speaker is going to have one of the largest tonal influences on the sound you experience (besides HU).


You should go with a dedicated mono block, class D amplifier for your sub (whether Alpine or SI or whatever). Class D amplifiers don't make your car's electrical system work as hard as a Class A/B for the same output power. If you go with the SI Mag, I recommend the JL 500/1 - the Mag is rated to run 500W-1000W RMS in a 1 cu ft enclosure.
