Im thinking of purchasing the loaded thunderform box for my 99 reg cab. Does anyone have opinions on how good they sound. Pros or Cons are all appreciated.
Thanks

I have the thunderform box as well, The subs are 8"'s. Anyway.
I've been having problems with mine, limitations you could say. Apparently the RT-120 amp I have running them is underpowered causing too much distortion. The result, this is the second time I've blown the speakers. If it happens again, I best be getting a refund. I am purchasing a new amp. T-6500D (MTX) and reccomendations on what to power the subs, this seemed like my answer.
thanks.

What I've done: K&N filter, Magna flow custom exaust (From where cat's join, 3"in, two 2.5" out the rear), Michelin LTX M/S 265/75/16's, MTX Thunderform custom box with two 6000 series 8" subwoofers and Mtx 120 amp.
Plans: Lund hood deflector, superchip, Poweraid, Xenon sport Flares, (custom ram-air idea?)
New: Pioneer DEH-P6300 Head unit (I definately reccomend it!)

 

I've got the thunderforms loaded with 6000s. They look great, and the sound is good up to a point. The 10s can't handle much power below 45 Hz without breaking up. If you want a hard hitting, nice looking system they do great, but if you push it very hard you'll find it's limitations. IMHO, two 12's in a custom box would do much better.

 

I've had a Thunderform for a while with the MTX subs.

Just installed JL Audio W3's. 500% better.

IMHO, buy it without subs and install a good set. The MTX's are alright, but for a little more $, you'll be much happier with the sound.

Those of you have the Thunderform for the regular cab, can you answer this please.

Is the 1.8cu ft. of the enclosure volume- is that 1.8 cu ft per sub,or is the 1.8 cu ft. shared by both subs?

 

I have a question to anyone who has/had the factory 6 disc changer in a regular cab. I'd like to get the thunderform but I don't know where to relocate the changer as it is presently mounted directly behind the passenger seat. Any ideas?
