i'll be finishing my interior speakers soon, its been rough these past few months trying to save money.

i got a poineer DEH3800 for my HU.
i'll be getting the Polk Audio DB5250 Component speakers
and i already have my mids, 6x9 inifinity reference, and the amp.

deciding on what sub to get.

I'm still undecided. But i know I want KICKERs subs. I was looking at 2 12' L5s at circuit city, those sound nice, they're expensive but i can always shop ebay. This i was thinking on 1 12" L7.

but getting either subs, will it drown out my sound? I dont want the affect of people hearing it outside the car, but not drowning out the sound. i love loud music and eavy bass.

and as for ohms, thats what confuses me, 2 or 4, dont really know the difference.

can somone help me out plz?

They will not "drown out" your sound. The operate in a different frequency range than your other speakers so they will just add sound from the frequency range below what your other speakers cannot reproduce. You get more sound but not more of the same.

As for the level being too high compared to speaker output, that's what your sub control (if you have it on that deck) is for. If you don't have sub control on that deck there are some ways to get a level control from the HU but you have to not be using the front or rear pre-out, for example.

As for the overall level, that's what your volume control is for, lol. If you don't want people hearing it outside the car you'll just have to not turn it up as loud. It's just like if you were at your home. If you didn't want people to hear it outside of a certain room or outside the house (perhaps like neighbours) you'd just have to turn it down.

Now you can sound deaden the car with mat or spray like Dynamat, which will help, but it's not going to magically stop all the sound from travelling outside your vehicle. It'll just help a little.

The impedance and coil configuration you need is dependent on what amp you plan on buying or vice versa. You have to match your total load impedance to what total impedance (all coils and drivers wired together) you want to drive with the particular amp you plan on, to get maximum power.

Typically you want either a 1 or 2 ohm total impedance and an appropriate D-class amplifier to go with it. Going after a 2 ohm total is good because there seems to be more selection of amps doing their full power into 2 ohms rather than 1. However if you select an amp that does it's full power into 1 ohm then you'll want to go after the 1 ohm total. Get it?

if you want real loud bass maybe you should get 1 15" L7, You might not get what you want from a single 12".

As far as drowning out your sound, like said above^, different frequency. You'll be able to hear your mids and highs just fine.
