Question: Is all the wiring needed included in this?    i.e. the RCAs, hot and ground leads, etc? Or would getting an amp wiring kit be worthwhile?
Document: There's enough walkthroughs on Wrangler forums to show you which wires to tap into, etc.For a Wrangler you'll need a line-out converter and a wiring kit (hot lead, ground wire, remote wire, and RCA line-outs--- amazon recommended a kit from Boss and I got that one), oh and some 18-22 gauge quick-splicers.
For me it was a bit easier, due to still have direct leads to my battery for power. But all you have to do for this beast, is plug in power, remote, and audio (from your stereo), and your ready to go. The customization is fairly well done, as the included built-on amp has pretty much all the mainstream toggles and settings that an average person would want to fool with.I had this in a small commuter Honda Civic Hatchback.
I also suggest getting at least an 8 guage wire kit...no need for a RCA crossover kit. This unit has one built in. Install was easy. The only problem is if you are attaching it to a stock deck like I did, you will have to splice the rear speakers to connect the sub to. The hard part is telling the difference between positive and negative on stock wiring.
This powered subwoofer sounds incredible for what it costs. It's well worth the money paid. High quality materials used in it's construction. The installation/setup instructions are clear and easy to understand as long as you have some background in electricity/wiring. The included remote for bass level makes it an even better product. This lets you adjust the bass level from the drivers seat. I usually decrease the bass level for FM radio listening as opposed to CD's.Please remember to purchase a Amplifier wiring kit also.
I am a 30-something, married father, with a past that included building subwoofer boxes with 12's, bandpass boxes, blasting Pantera, Dr.Dre, setting off car alarms, etc.. so I do know what "real" bass sounds and feels like.I am not in the market for that anymore. But I do require way more bass than most factory car stereos offer. I came across the Infinity Basslink and thought it would give me exactly what I was missing.
I have a 2007 Ford Ranger extended cab and I was looking for something small and with a built in amp if I could, as I already had the wiring ready and wanted to plug and play. (I previously had a HUGE box with two 10"s in it. Don't know how I ever got it in the truck.) This is absolutely WONDERFUL! Easy setup and the included remote is very convenient and a nice addition. Compact enough to hardly take up any room at all!
Selected this powered sub for my mom who didn't want a banging system, but just wanted a bit more tone in her '98 Blazer to back up the Kicker DS door speakers I bought and installed for her at Christmas. Install was nothing bigger than average amp and sub install. Power wire and fuse block from battery, RCAs, remote, and sub adjust wires from the radio to the sub in the back, and a ground from the sub to the nearest solid ground point. Basic and run of the mill.
While they have a fun if not precise sound, and smoke anything else in the 200-250 range, you have to buy a new one after every 2 years or so. They just don't last. One started draining my battery and the car would be stuck until I found the source of all the frustration - a dying sub that tried not to turn off. You are better off getting an amp and speaker separately.
Install is a breeze because the amp is built in. All you need to do is supply power, ground, and signal. It took me 1 hr to get it in my car to test out, and 6 hours with a buddy to install it cleanly with all wires tucked and sub mounted rigidly to trunk floor.I'm very happy with the Basslink and would definitely recommend this to anyone looking to add some more low end to their system. Not for bass heads.
I think this is a great deal for the price. Has great bass for a small package, nice looking and comes with good options (speaker wires,remote wiring,brackets,etc.)
Answer: I believe it is but it's worth the extra $$ to get a good kit with heavier wire.
