Default 2017 WRX 15" sub and LOC install question!

hey all,

Just recently purchased my WRX! looking to put in my old 15" Dayton Audio Subwoofer. I was wondering if any of you guys have had trouble fitting the subwoofer into the trunk. i'd like the subwoofer to point outwards away from the inside.

also looking to upgrade the speakers and amp while keeping the stock head unit. i do not have the upgraded sound system, just the base. have you guys had any luck using a LOC to get the signal out to the amp? im looking to spend around $200-300 on front component speakers. still budgeting out amp money. im willing to spend $100-200 on a solid LOC also. i have my old Polk DB651's for rear fill. any help, input or warnings is much appreciated!!

I have a 10" JL sub in a wedge box that doesn't take up much room and can be moved around if needed. A 15" is a whole other animal! I have a sealed 15" Dayton in the house and that's a big heavy box. Are you building a box for it? If so you could make it the whole width of the trunk and deep enough to get the right volume. You are going to have to worry about rattles also! I sound deadened the doors and rear deck - recommended!
Many amps have speaker level input and don't need a loc. I have a older 5 channel Alpine running the front speakers and sub - works great running the speaker wires to it - did not need a remote turn-on wire either, it powers on with the hu. The newer alpines would work great and be nicer yet - I have seen them under $300. There are many other brands that would work also (NVX comes to mind)

If you are keeping the stock headunit do yourself a favor and get an Audio Control LC over a regular LoC. The sock HU rolls off lower frequencies badly over 25/40 volume.

I do plan to build my own box for it. But I dont want to stray too far from suggested air space. Im pretty open to getting a new subwoofer also if this is too big of a problem. Sound deadening is definitely on the to do list. How's the sound quality when just using the high level inputs from the amp? Are you on the Stock head unit?

That's the exact line of LOCs I was looking at. Made my LOC budget around those!

Yes on the stock head unit, amp under the drivers seat - everything looks stock. I have NVX component speakers in the front (from Sonic) I didn't bother with rear speakers. My system sounds amazing - good clean & powerful. The bass from just the front speakers is pretty impressive. I have a gain control for the sub on the dash and usually have that turned down - really not needed on most songs. I did full sound deadening on the doors (cld, mlv, ccf) and I think that really helps. I am a audio nut - have about $15K into my home system so I know what good audio sounds like, very happy with my car system now. I would like to add a DSP at some point (cause you are never done modding!)

Awesome! This gives me a lot more confidence in my plan. Thanks for your input. I looked into DSPs and I don't think I'm ready for DSPs yet. Lol but yea, I wasn't planning on spending much of anything on the rears but luckily I had my old ones. If you got any more suggestions, I'm happy to hear them

When wiring your LOC where are you guys running the 12v constant?
