Few Questions About Installing A Boss 10"

1) You have to connect the remote turn-on lead to something that is switched ignition. (like the 12V power outlet in the center console.
2) Both.
3) Probably, depending on what is included in the "kit".

 

8 Gauge is a little overkill for a BOSS, I used 12 Gauge that came with the BOSS. make sure to run BOTH positive and negative power leads directly to the battery. The sense line will work off the cig lighter power. it's off when the car is, perfect.
If you can locate a schematic for a non JBL 2010 Electrical system it would be a help in tapping into the speakers!
You do not need heavy gauge wire for the speaker run from the speaker to the amp. You need signal, not power. All that happens is the speaker feed is terminated into a resistive pad, then the low level signel is fed to the BOSS amp!
I threw my BOSS in the back, then camouflaged it!

 

I wouldn't recommend bandpass as the response isn't always flat.I'd use bandpass if your looking to play one type of music like hip hop where it would be ultra efficient( subs will play louder on less power). I would go with a sealed box setup if your after sq(uses more power, less output), If you really want to bump in the whole food's parking lot I suggest a ported box(good compromise between power and output)I always recommend ported if your after some chest pounding bass . Using higher gauge wire is warranted on higher level setups like on 1000 watt rms or something. Car Stereo Wiring Sizes | Car Audio Advice | Stereo Terminology And Education Since you are running a 160 watt rms I assume sub you could go with 10 gauge as recommended.
10 awg = 60 amps
12 awg = 40 amps
14 awg = 25 amps
16 awg = 15 amps

This is such a small setup I probably wouldn't waste the money personally, Thicker wire will help you get the most out of your sub as the wattage gets maxed out. More current thicker wire.

 

hmmm I have the 2010 jbl package and tbh I think it rocks. My previous car had 400 watt rms infinity amp and it could get major loud, but I think the jbl gets loud enough for me and all that I need to do is add a hefty amount of bass.

 

Initially I got the BOSS 1200 powered sub and stuck it in the rear storage compartment under the floor. I was pretty happy with the sound. Unfortunately the amp burned out... just from adjusting the sensitivity. Rather than paying an arm-and-leg to send it back for repairs, I went ahead and built a custom enclosure with a 10" Hertz sub and got a JL HD900/5 amp. I am really happy with this setup now and the JL amp is rock solid. A lot more than I wanted to spend but sometimes it just makes sense to pay a little extra.

 

yeah I think the jl amp is a good choice, aloh with a good sub. for a stock stereo yes I would upgrade front speakers at least and sub

 

I've never been a fan of those wiretaps, they don't make a very good connection. I prefer to use an inline stripper like this one:

Then splice the wire you want to attach, solder it, and use electrical tape to insulate it.

 

if you havent purchased anything take alook at this

i was really thinking of buying this, but instead i went with 2 lanzar 8 max pros.
