Re: Adding sub to ba system

You will not be able to use the low frequency output from the Boston amp. It simply does not provide the correct input level to be used on an external amp, if I remember correctly. As Brent stated, you can opt to find an amplifier that allows for high level input, but that will only save you the cost of an LOC, which is $13.88 at Walmart for a fixed level Stinger LOC. I would second Brent's opinion - start from scratch and have it done right. You will be happier in the end. I only paid $125 for the install of the LOC, including all wires and the fuse. Hope this helps!

The 10ga lamp cord for the amp to sub connection should be fine. I thought you were talking amp power cord there, so my bad.

There is a difference between the low level (this has to do with frequency) on those speaker wires (which were scrubbed by the amp) and line level (has more to do with power). Line level is a low power signal via RCA cable which is meant to go from device to device. Like I said before, if the amp you choose has a speaker level input, then your existing wires should be fine. But if you plan on using RCA cables as an input to a typical monoblock sub amp, you'll need the line-level signal and cable.

Re: Adding sub to ba system

I ran a infinity basslink a few months ago. Just remember when you hook up your LOC, wire it in after the amp. Not the radio. My LOC is tapped in right at the rear speaker in the door. Didn't know if that was already explained. Depending on what you want for bass, i'd just to a preloaded enclosure/ w amp. That way you don't have to deal with half of the mess of hooking up your wiring. Just a power, gnd, turn on, and rca's. For the turn on there is a empty ignition terminal in the fuse block at the kick panel. (look at omlete's thread).

My last jeep I had a 3000w system in that bad boy. So If you need any tips on running wire/ and or how to install I can help .

So from the taps of the grey/ yellow wire and grey/ purple I install a loc? Then From there I use the rca's to the amp in back with a sub? Will the sub need its own power or does it get its power from the amp like a speaker?

You CAN put a LOC on those wires, but I would still recommend putting the LOC on the full spectrum sound that is amplified to the rear speakers instead if you want the best sound quality.

And yes, the LOC, once tapped into the amplified speaker wires, will provide the RCA line-level outputs which will be plugged into the RCA inputs on your amp. Remember that the LOC usually requires a power source too. Because it's such low power I think I may have permanently wired it into power, but honestly I don't remember.

The sub will not need it's own power, as the lamp cord you'll attach from the amp to the sub will provide both power and sound signal. However, the amplifier needs to be powered by a good gauge wiring kit (as I said before).

Re: Adding sub to ba system

I have to question some of the advice given here because if you read the directions for adding the Mopar - Kicker sub it instructs you to tap into the driver's door speaker wiring for your stereo feed, but everyone here is saying not to.

I followed those instructions, using the high level inputs (no LOC) on an Alpine amp and sub combo and the thing sounds awesome.

I could be wrong, but based off of that information, it seems like the MOPAR Kicker system amplifier must have a speaker level input, which basically means it has a LOC built in...

But then again, I know next to nothing about that system.

And obviously, as you mentioned, your alpine has speaker level inputs, hence the lack of a need for a LOC

Actually that's a sub/box/amp combo with everything built in. You'll note that although it comes with the high level inputs you want, that amp is rated at 100w MAX, which is hilariously low. Not to mention that the sub installed in it is probably the lowest line Kicker makes. At volume, there would likely be very noticeable distortion. It's likely that the OEM BA system with paper cones that you have is higher quality than that kit.

That being said, all of my trash talking aside, if you just want a little bit of rumble and don't mind rattles and distortion, then it's not a horrible kit for that price. However, don't delude yourself into ever comparing that combo to the likes of the MOPAR Kicker system for the WK or especially to a custom setup which most others have on here like mine.

As a reference point, my kit was under $400 for the box/amp/sub/LOC and took about an hour and a half to install.
