Powered sub's

Somebody needs to make a fiberglass replacement for the rear door plastic. Then a sub could be easily mounted there. A 8" quality sub would be plenty of bump with a 250w amp.

I have a 10 inch high excursion sub back in mine, mounted in an acoustic suspension (sealed) enclosure for tight, loud, not boomy bass. Used copious amounts of dacron filling (walmart) to stuff any gaps between the body, enclosure, and stock spare cover to dampen any unwanted resonance. Of course multiple holes were drilled in the spare tire cover in a circular pattern to allow the sub to speak. Then affixed some very high density foam packing rubber to space the the plastic spare cover from the enclosure and tighten the fit even more.

Its a very, very tight fit back in there, but it rocks very hard without any unwanted rattles or resonance. The entire interior was dampened with Dyna-mat Extreme by the PO.

Full disclosure, I did not design or mount the enclosure itself, tho I did contribute to it as loudspeaker design has been another hobby of mine since my college years.

The sub is driven by a two channel 700W amp, and the front and rear JBL 6.5 inch component speakers are driven by a 400W 4ch amp. Its all fed signal via an Eclipse head unit with its incredible 8v line level outputs. Power is distributed with a gold plated power block up front @ the battery using 10 and 8 gauge copper.

There are no massive capacitors, no signal converters, combiners, splitters or other such mojo. Its very straight forward, by the book. As such it works very, very well.

Its not a ghetto rattlebox. Its not meant to thump from a block away. From the outside it does not sound like its shaking every metal fitting on the vehicle apart. On the inside its amazing. All my friends who's tastes range from country to hip-hop to techno or blues ask to "hear it in the VX".

Thats good enuff for me.

A sub mounted in the rear door is awesome. I have a rockford fosgate 12" stage 3 shallow mount in a sealed enclosure. Amp is mounted under the drivers seat so there is no real loss of storage space and with a metal cage over it I dont have to worry about cargo shifting and damaging it. And it will BOOM.. Think I got the sub on amazon for 99 bucks a while back, and built the enclosure myself and covered it in vinyl to give a clean look

I never liked the idea of using the head unit to power the speakers and/or subs.

Instead i ran a entire new and high quality wiring and left untouched the factory wiring.

I purchase four good ( and expensive,though ) RCA wires to hook up the head unit to the digital EQ,then connected the amps with the EQ.
The results : better,quality sound.

Both,speakers and subs are all powered by the two four-channels amps,one for the speakers and the other exclusively for the subs (@ 4 ohms )
Thanks to the digital EQ I can squeeze better sound from the head unit instead of relaying only on the built-in EQ.
