Question on SA-8 and amp

I'm in need of a sub and amp for a 2011 VW Golf I just picked up.

After reading through various reviews I was almost dead set on an Alpine Type R 8".

Then I started reading about the SA-8 D4 and how much everyone seems to love them and they trump the Type R's.

Here is what I'm after. Small sub that can blend nicely with the stock system but also pound based on what I'm listening to. I listen to audio books (hey, I've got a long commute and it helps ease the road rage) and any type of music, be it country, rap, rock, metal, pop etc...

I have $300 to spend on a sub/amp combo.

I've already got the MDF to make the sealed box. Size will be somewhere around .45 - .65.

SA-8 D4 $139

What are your recommendation and input?

Looking to order soon.

Thanks guys!

Welcome .... :drink40:

Your choices look good. The BA amp is not a bad buy at that price. Build the enclosure sealed and run it at 0.6ft^3 after sub woofer displacement.

Will the SA-8 D4take 500watts rms daily?

Straighten me out on the ohms thing please.

The sub description says its 6ohms. But it has dual 4ohm voice coils?

I planned on connecting the amp to it with a 2ohm load pushing 500 watts.

I must be missing something. Read so much lately its all becoming jumbled.

Yes the SA-8 can take it daily as long electrical is strong, enclosure is within spec, amplifier input/output is not clipped and the person behind the volume knob.

The SA-8 are dual 4 ohm. When hooked up in parallel it will result in a 2 ohm load at the amplifier.

If you are looking to run a sealed enclosure a sa8 may not be the best choice. I believe the E8 is more suitable for sealed.

Actually the SA-8 can be ran sealed with a slight decrease in output but the overall sq is great imo. The E8v.2 sounds great in a small sealed enclosure and are suited better for sealed applications on higher power applications.

wow, recommended Sealed Box: 0.280 ft^3. The smaller the better for me because I need to retain as much hatch space as possible.

The E8 says it will only handle 200watts rms. If its like the SA-8 shouldn't it be able to take 300 watts at 4 ohms?

Alpine has diagrams on how to hook up the subs for various ohms does Sundown?

Would you guys recommend doing a fibre fill?

Noticeable difference or a waste?

Only way to tell is test with and without and see if you hear an audible difference.

Polyfill is mainly used to make the speaker see a bigger enclosure if you are going undersized.

Amp and Sub have been ordered. Let the fun begin!

How many fractions of a cubic foot does the SA-8 take up?

.07 ?

Trying to build the box in sketch up and using the RF boxwizard for sizing.
