So, can someone explain what all the different terms mean, because when I'm comparing subs all I see is numbers. What is rms, peak level
Does the number of ohms have anything to do with the equation
1 or 2 way subs?
If you have 2 subs, do the RMS and peak add up? I.e. 800W+800W=1600W?
How do you determine sound quality? What kid o amp should I get/ do I need?
If I plan on getting an aftermarket radio, shoul I take that into consideration when picking subs?
Can I also add in door subs if I have a base model?
Thanks!

Am quoting the original so i can remember to touch all basis lol.
Sound quality vs bass vs power
Its easy don't get confused on all the terms just focus on the simple.
Rms is continuous sound output vs peak is that max both an amp can put out and a sub can receive. No 800+800 doesn't add up 800 is your total. An amp may say ie.800watt max but 700rms . This means it will supply 700 watts of continuous power and at any given moment you can demand a max of 800.

Ohms is how deep in frequency the sub can go meaning negative decibel . Don't worry so much about it most subs can provide more than enough bass unless your doing competition.
The alpine type R and type S is one of their better subs. Here's what i would go with...
2/10"- 650-800watt max
1000-1500watt amp
No need for door subs
Pre-amp to control mids and highs
Don't go above this otherwise you will need extra battery and resistor and volt meters..its a pain trust me

You mean I'd need an extra battery?
What if I'm having a shop install them, would it still be as much of a PITA. I'd assume they know what they're doing.

Nah bro.. Stay below these numbers i gave you and you will be fine with one battery .. The install is not as hard as ppl think. It just takes time and patience.

Do you promise me, that 800 watt subs will gt hard?
Because I want them to be almost painful
If you get the 2ohm subs you can bridge your amp down to 1 ohm and get the most power from your amp I'm running an old school 1000 watt Memphis mono block amp with no problem then you need to decide if you want to run ported boxes or sealed the sealed box will give you tighter base and the ported will give you more of a rumble in my opinion you can get more sound from 1 12 in a ported box than 2 10's in a sealed one.

What about 2 10s in a ported box?

Bridge 2 8ohm speakers- amp working at 4 ohms.
Bridge 2 4ohm- amp working at 2 ohms. Only Rockford and Phoenix gold amps go below 2 ohms. Phoenix gold, you can get down to 1/4ohm.

I use to have a 200watt Max amp but at 4ohm, it was 300 Watt. So just read up.

A good made box is 90% of the battle when it comes to sound systems. Find somebody who knows what their doing and is very good at making boxes. A good made box will make a set of walmart subs and amp sound good. Trust me. My best friend wins competitions with many different setups. But no matter what he runs, he has the same guy make the box specifically to his truck and subs. Dont buy a prefab box. It wont be near what it could be.

Define bridging please :p
And hat would you do?
1 12" alpine type r
Or 2 10" alpine type s
Both ported
Not sure of amp yet :/ and can you re explain ohms again please?

You change the ohms by the way you wire the speakers together its all complicated but you just got to study up I'm getting 2 ohms because I'm only running one sub but if I had 2 I could bring it down to 1

I know tat if you add more circuits, contrary to common sense, total resistance will go down.
I think, I took physics last semester :p

I know u can bridge parallel or series. 12 years ago not to many amps went below 2 ohms.

If u get 2 subs, hook both + to L+ and both negative to right -. The amp should have it marked.
