What sub 10"?

This is my first post. I just bought a 2002 f150 regular cab and want to install 2 10". The amp i'm planing to use is an old soundstream reference 500. Its rated at 500x1 at 1 ohm. Ive been doing some research in this forum but havent yet decided on what is the best option for me.  Thinking of getting some solo baric L5. What do you guys suggest?

Also looking for a 4 ch amp. I wanted to go with a soundsream so that the amps look the same but i think the new soundstream amps are lame. I currently have a lil wonder 4 and im living it in my old car to sell. Any sugestion on what amp i could get?

Open for good sugestion.

The w7 wont fit due to the mountig depht. My budget for both subs is around $300.

Im planing on getting the 4ch amp in a couple of months and the budget for that would be 200- 300.

What do you guys think of the alpine CDA-9833. The reason im thinking of his hu is because of the ipod conector. I listen to my ipod all day and want to be able to control it throught the radio.

Thanks guys 

check the new Arc, Kar series or a good old Image Dynamics

1) Your sound goal .. SPL? SQ? Do you listen at moderate levels? Plan to compete? What kind of music do you listen to? What type of sound have you liked listening to? Boomy? Tight? Clean? Deep? Just loud?

           I normally listen music at a moderate level. I will never take my truck to a competition. I listen to all type of music but my favorite is hip hop and rap. Looking for tight and clean bass.

2) Your volume(size of the box) requirement / goal.

Because of the limitation of space i have. I calculated a maximum of .80 sq ft. of colume. Im going to be doing the enclosure myself.

3) Your budget.
Since im going to buy the system by stages i currently dont have a fixed budget. But i wont expend more than 250-300 in subwoofers

Fof the 4-channel amp i was thinking of getting some good components for the front ($200) and a pair of good coaxials for the back ($150). Open for suggestions in this area.

I'm not focused on 2 10" i can also put 1 10" but i wouldnt put 1 12" because of the space limitation. I also thought of putting one Solobaric L7 but not sure if that would be over kill for my truck (it sure would hit hard).

The reason i was looking for a soundstream amp is so that i would have a matching pair of amps, but if dont find a GOOD reference or rubicon 4ch amp, i'll end up looking for other options ($200-250)

Thanks for the help

Starting to lean towards 1 eclipse aluminum in 10".

Anybody have any other sugestions on other subs?

Whats a good online store to get eclipse equipment from?

Ive decided to go with the 10" aluminum series from eclipse.

Should i go with one or two?

Anyone else have any sugestions on if i should stick with just the components up front.
If i only install components up front and nothing in the back i can get a good 2 channel reference amp and put some MQ quarts PCE216 or some koda 6.1 (any other sugestion on co,mponents), but im not sure about not putting speakers in the back.

2 only gains you 3db with the same amount of power spread over 2 subs.  If you also double the power to each sub you gain another 3db. 

3db isn't a huge audible gain.  Unless you are competing or obsessed with SPL, there is no need for 2 subs, in my opinion.

I think you're right to focus your money and effort on the front components and a very high quality 2 channel amp.  Even if you do decide you want rear fill, I'd just stick w/ the factory speakers and use the deck power.  Rear fill has minimal value, in my opinion.  Even if you decide you like it I would place it last on my budget. 

I'm also looking for a good place to buy Eclipse stuff.

I live in Puerto Rico.
