What Amp Setup Would Work Best

So the Shivas RMS at like 250? And should i get other component speakers also? What would go good with the Shivas?

And how could the Shivas out porform the alphas? Does the RMS not matter? And in that case what does? And will i have to upgrade my alternator?

For components, check out CDT, Adire, Resonant Engineering...just to name a few. You will probably want an amp for those too (50x4 should be fine).

You shouldnt have to upgrade your alternator if you keep it all below about 800 watts total (i kno this is controversial). As long as you dont play it as loud as possible all day long you should be ok if you keep it under 800 total.

The Shiva's will outperform the Alpha's because they are a QUALITY sub. Not just some mass produced p.o.s. from japan. RMS is just a thermal rating. It is how much heat, in watts, the voice coil can handle. The RMS on the alpha's is probably a little high just to reel in unsuspecting customers.

Happy shopping

If you decide to go for an s/q setup, a set of IDq10's would good. Keep in mind Justin owns a shop that sells like everything needed, and he has a set of Rainbow Vanadium subs and an ARC amp that he wants $300 shipped I THINK...dont quote me on that though.

So if i go with the 2 Shivas will the amp need more than 1 channel? Or just a singal channel amp of 600 watts?

one mono class-D 600 watt @ 2 ohm amplifier.
example: JBL bp600.1 and Kicker KX600.1

wire two 4 ohm subs in parallel and you have a 2 ohm load on the mono amp.

The Shiva is a dual 8 ohm woofer.

So in order to achieve a final 2 ohm load, voice coils in parallel as well as subs in parallel.

(sorry kiki, you made it sound like the shiva was a single 4 ohm v.c. sub)

With that in mind, you will want a 2 channel amp for a single shiva. That way you can get the most power for your dollar (4 ohms bridged). For two shivas, you will want a monoblock amp as mentioned by Kiki (2 ohm load).
