This is a copy pasta from the caraudo.com forums I put up..everyones advice so far just seems to be from biased vendors..anyway....

Hi, first off I am not sure I am putting this in the right subforum. Anyway, I will get right to the point.

I have a 2008 Evo X that has the stock Rockford Fosgate system. It has a 10" sub in the trunk and the amp is under the drivers seat. I would like to keep it as close to factory look as possible. I need the trunk space I have since the trunk is so tiny as it is and I have 2 small children.

I have a odd head unit I bought and installed, it runs Android 4.1 but it does have front,rear and sub rca outputs.

I was thinking of doing the same thing as this https://www.evolutionm.net/forums/8137796-post26.html in terms of the sub. It will let me retain the stock enclosure(if you want to call it that). I was also thinking of getting the JL 10W3V3-2 as well.

Amp I was thinking the Alpine PDX-V9 as I know it will fit under the drivers seat.

Speakers Image Dynamics Ctx65cs for the front and CTx65 for rears.

Amp kit KnuKonceptz KCA Complete 4 Gauge Amp Installation Kit

RCA's Rockford Fosgate RFI-10 Twisted Pair Signal Cable -10 feet x3

RAAMaudio Package # 1 for deadening

and 2 sets of adapters from Crutchfield for the door speakers.


I mostly listen to dance music(edm) 80% of the time but im into everything. Rock, Rap, NPR(im almost 40). I am looking for sound quality over SPL but I still want it to kick hard.

If you look at what I have listed I am looking for bang for the buck. I will buy from the cheapest place possible without getting ripped off. When I was younger I had done crazy installs on my cars but it has been a while(15 years) since I actually upgraded my factory system in a car. From reading it seems a lot of people just say to ditch the rears, JL is crap etc..

Anyway, im looking at around $1200 when all is said and done. What am I doing wrong, what am I doing right.

I will say that the SUNDOWN AUDIO SD-2 10" has caught my eye.

Any help would be appreciated. Thank You

 

My suggestion is if you use the stock box to install another sub into it, dampen the hell out of it ! The stock box resonates like crazy because it's so cheaply built.

If you're willing to put the time and are handy, go ahead and build one out of fiberglass. You can thicken it up a lot more and get a much better sounding box.

I removed the liner in the left side of the trunk for extra depth for my box, and honestly, I don't believe I lost any trunk space even after moving up to a 12" sub.

 

sounds like good stuff, love RAAMat. I can also get Dynamat Xtreme kits at cost too if you need some. I relocated my battery and washer tank to fit a 13" JL under the rear deck

I have been rethinking the sub. My real problem is TIME. I would try and make my own fiberglass box because I am handy and love to make stuff, but my wife would freak.

I am going to go to a local shop to see what they price out as, also thinking a wicked cas. My other thought was going ghetto and just taking out the stock enclose and sticking a square sub box in there.

 

Wicked CAS will fit great, I had one.
