Major JBL stereo upgrade but keeping stock HU

Well I worked on my hybrid battery again and got it much more balanced. The hybrid noise is much quieter! I could live with this.

The solder joints all looked good inside the processor. I haven't retried the iPod and still at a loss with this bs. Lol

View attachment 212096 View attachment 212097 View attachment 212098 Sub Enclosure cont... The NVX sub enclosure is model # NVX BOOST BE_TOY-PRIG3 NW 104V2. The 104V2 part of the model # refers to the model of the pre installed NVX subwoofer if you would like to check out the specifications of the included Subwoofer. I basically only wanted the enclosure so subwoofer specs did not matter to me. The box comes with some nice Spring post speaker terminals of good quality. I upgraded the internal speaker wire to the KnuKoncepts 12 ga. Kord speaker wire that I used to run from the sub to the amp rack. The internal wire was then sound treated with foam and Tessa tape to reduce the wire slapping around inside the box. The hand laid fiberglass box looked to be about 6-7 layers and no less than 1/4"-3/8" thick in each place I was able to measure. It has a smooth black colored exterior on the places not covered with fabric and the interior finish was also nice and smooth. I did not do any sound treatment to the interior of the sub enclosure yet. I wanted to hear it un- treated first and decide if any sound treatment is needed. The Box fits perfectly in the factory rear drivers side cubby that used to house the small storage tray. It takes up little to no space in the rear of the vehicle. A big plus in a small vehicle like a Prius. Installation is accomplished by using the supplied nuts and washers that attach to the factory hold down bolt that used to hold down the storage tray. I installed two additional threaded nutserts into the floor below the sub box for some extra attachment points. This sub enclosure with the subwoofer weighs about 20 lbs and I did not want that thing hurling thru the interior in case of an accident. I did find that because of the speaker cover that I chose to use, that I did have to trim about 3/4" off the storage tray that covers the spare tire so that the entire tray could be lifted on the left side and give access to the spare tire without having to remove the entire tray since my amp rack is located there. Secondly when I went to Install the carpeted folding storage area tray that also needed to be trimmed slightly to clear the subwoofer enclosure. Also the rear carpet pad needed to be trimmed as well. Here is a pic of the stock subwoofer grill that comes with the enclosure and fits on the NVX sub.It projects out from the enclosure less than the grill I chose to use with my Kenwood Sub. Using a grill like this may mean not having to do as much if any trimming of the storage tray and the storage cover. View attachment 212099 And yes I know that the carpet needs a good cleaning!!!

Hello, I'm wanting to replace the nvx subwoofer that came with the enclosure as well. Did you fabricate that trim ring yourself?
