I recently met another member, IRL, that had installed the Kenwood KSC-SW11 as ROX shared HERE. I liked that the KSC-SW11 fit so well, in the factory space, and made an improvement to bass delivery more inline with my expectations for the factory audio system. So far I’ve tried not to do anything to my car that can’t be 100% undone, by me, in my garage. After that member shared ROX’s post and I saw how clean the install was, I was more than willing to give it a go. While looking for various bits, and the best pricing, I came across the JBL BassPro Nano. When I COMPARED the BassPro Nano to the KSC-SW11 it seemed the Nano would also fit the space while providing a bit more power, having a larger woofer, and offering a longer warranty. So, I picked it up. It fits quite well too, I think, as shown HERE.
I bought some of the bits recommended by ROX including the Molex connector which connects to the factory subwoofer wire connection. For the speaker wire male pin, I bought both the one ROX suggested, and a slightly different option I thought might work better for the smaller wires I’d be using. Turns out this smaller CONN PIN worked well.. I purchased THIS tool for crimping the pins, as I didn’t already have one for these types of pins. I think it did a good job as seen HERE. I did not need to add any length (wire) to the harness included with the BassPro Nano. I also bought THIS SAE extension cable, mostly because it shipped quickly. I cut one end off with about 4 inches of wire length, and connected it to the BassPro Nano’s harness for the power and ground, via solder and heat shrink. I connected the other part of the SAE extension cable to the fuse block for power, and the OEM subwoofer bracket for ground. There are other options which may be easier such as THIS which has an inline fuse slot built in and already has a terminal ring for the ground. With that you could replace the positive side with a female spade terminal connector, something like this, and the fuse with a 15 amp, then be set. I used the same Tesa wire loom harness tape ROX did, from HERE, to make a harness as seen HERE. With it there are two quick connections which supply everything the BasePro Nano needs. When using the speaker level inputs the remote turn-on wire is unnecessary. I went ahead and doubled it over and wrapped it up with the Tesa tape. I ran the SAE wire under the Hatch foam, and up along the other wires, similar to the OEM subwoofer speaker wires. You can see that HERE. Please ignore the other additional wire (with the twist ties around it) I will soon be adding another battery for my camera system, and will clean that wire up after that. I have decided not to install the remote bass control module for now, it seems the control via the OEM adjustment is sufficient, for me.
I just hooked this all up and haven't had the opportunity to compare it to the other member’s KSC-SW11 yet. I can say that it does more than I expected. I currently have the gain at ~25% and no bass boost, so there’s more to be had out of it. The low pass filter adjustment does nothing that I can perceive. I suspect the OEM system is already sending only lower frequencies via those speaker wires. As I said, this thing exceeded my expectations, but perhaps those were low relative to other’s. Really I just wanted to perceive bass at a level I expected from the factory system, this can do that and much more. The rest of my system is factory, and clearly outclassed with this. It has me considering upgrading the rest, but I have some concerns for weight. Speaking of weight, this has added about 3.2 Lbs. (according to my digital bathroom scale, however accurate it is,) over the factory setup, including the additional wiring. For me, that is acceptable, especially considering the subwoofer and most of the wiring can be removed in about 10 seconds, if desired.
Anyhow, I thought I’d share this as an alternative to the KSC-SW11. I may update later after some time, or if I get a chance to compare it directly to the Kenwood. LMK if you have any questions or suggestions.
