I've had mine for like 3 years now. They rock. Just put decent model subs in there, don't worry about the preloaded version. I have a set of RF HE series and they are ideal.

 

im in the process of making a box to hold 4 10's for my L. i personally like the looks of a carpeted box but thats just my .02

 

Why more? Just get 2 really good ones... I'm looking at 2 JL 10w7's 500 watt rms baby!!!

 

hopefully you mean 500 rms to each w7? Those JL's don't do so hot when underpowered...

 

Dub 7's dont do so hot in small boxes...how many cubic feet is the Thunderforms box?

Deep Pockets

 

well im a tall person so i have to have a shallow sub so that i can move my seat all the way back. so instead of what u are saying i plan on getting close to the same effect with 4 subs over 2

 

I tried 4 Jl 10's it didnt work, could not get the seat to go all the way back. Although 4 8's worked just as good and sounded better.

 

Five 10's... I'm 6'3" and very comfortable thank you!

 

Talk about killing two birds with one stone! Pounding sound and a lowering kit all in one.

 

You're not kidding! Add 100lbs of sound deadening material and we have the reason for my 14.4 stock quarter mile time. Tell you the truth, I wouldn't have it any other way, when the warranty's up THEN I'll go for some extra speed.

 

thats a good looking install. id like to see some more pictures if you have them. How much did you put into the install itself.

 

So, were to get an unloaded box of the original one pictured?

 

I've got a few pics. The install was done entirely by myself and some help from my girlfriend. I'm self taught, it all started out when I installed my first tape deck in my first truck when I was twelve (redneck farmer? very much so). I didn't record any of the measurements for the box... which I regret. A lot of time went into designing it with a few things in mind: optimal air space, seat position, and no modifying of any panels. I want to be able to take it out when it gets old and not have any damage to the panels, I plan on keeping this thing for good. It took me about a month to do everything on my spare time at night. I had the kick panels reinforced with some type of fiberglass that doesn't hurt plastic (I dunno, a body shop did it and they figured normal fiberglass would be too harsh for them). The sound deadening makes a big difference and I don't have any problems with the vents being blocked. In the doors I have Kicker 8" mid-bass and Clarion tweeters (had the tweets in a previous system). Kick panels have set of Phoenix Gold components (not a huge fan of them but they'll do for now). Front stage is powered by an old-school Phoenix Gold MQ-430, gold circuit board and excellent SQ. Source is an Alpine 7894. And finally, here are some pics:

 

Box in construction:

 

Finished box and sub amplifier. Amp is a US Amps that I picked up off e-bay for a good price, 1500 watts RMS. I know a 1 farad cap may not be enough for that much power (usually 1 per 1000 watts) but I'm still on the fence about whether they're even worth putting in. Subs are IDQ 10's.
