If I may step into this discussion, I was watching YouTube and JBL makes a woofer I know for the Toyota Camry & the Corolla, that fits right where the spare tire goes, it's a low profile, its height and with is small for a woofer and it mounts in trunk where spare tire goes its 1 bolt in the middle of it that mounts it in place , for its small size the JBL hits hard sound clean and it's not taking up any space in your trunk, i Believe they come in 8 , 10's & 12 in I believe the 10 in went for about $899.00 Or $999.00, that should work out great for u JBL makes some great sounding speakers , always have or you can do like the one guy said under your back seat, The speaker and the amp and door speakers are everything, Not sure what kind of sound you are going for or what price range is ? If you want send me a message what kind of sound you want , lots of bass or somewhat bass and what kinds mids and highs you are trying for and price point , & let me see if I can't make some suggestions in the right direction, I had all kinds of extreme bass to clean mids and tweets, then just the right amount bass , But if u don't want a woofer at all because space or just don't want it , then I would have to say Best buy has a pair of 6.5 inch with mid bass and separate tweeters and crossover, for $199.00 a pair with the right amp 2 pairs can sound really good , there's so much out there you can think it you can get it , I have a 2020 Toyota Corolla SE and it took me a year just to do all homework see what's out there what's the best for my money with the best sound , what I wanted is big bass when I want it , when I'm by myself or with a friend , when I'm with my wife I want somewhat bass but louder in mids and high , cause she wants to talk when where driving around so can't listen to much when she with me , haha and price is a big factor also , so with that i went with.1, 12 in SKAR box, 4, JBL 6.5 inch in the doors 4 channel zapco amp 340 watts pre-channel and SKAR 1000 watt bridge amp with base control knob gain, cause it doesn't have rca plugs in back of stock stereo I got the LC7 , it's really nice add on for my car , and kept the flat screen it came with , and its sounds better than i even imagined, best part got a lit from offer up and friends , so i saved thousands of dollars, and only paid a few hundred of dollars, and some barely used or never ,so I built my dream stereo on a little budget , and saved so much money Sorry so long but there's a lot to look at , think about and cost of it all , to consider , I love are ride and my music, nothing better than full throttle lol Hope this helps you , I am really thinking, I should have done the 8 inch x 4 SKAR woofers for the doors with separate mids and tweets competition even though its sounds great now , I wish i would have gone the extreme way, and finish it all off with the zapco 18 band EQ old school, At 57 I can now afford my toys now lol Good luck
