    Hi Guys,

    Brand new member, and brand new Tundra owner here! As others have stated, the "premium" JBL audio system is absolute junk. I'm reaching out in hopes of advice for an upgrade.

    My only goal here is to add some decent bass. I'm find with the rest of the speakers, but can't get over the lack of bass, especially with an 8" sub included.

    Here are my questions:
    1. If I simply upgrade the sub itself will that render any noticeable difference? Not looking to shake the mirrors off my truck or anything.
    2. I've read a lot about the ********* gear. If upgrading the sub alone won't at least double the current bass, would you guys recommend replacing the factory amp with the 5-channel ********* amp, or can I get away with only adding the 1000w sub amp? I'm really trying to take the path of least resistance, so running additional power, ground and remote cables is something I'm trying to avoid.
    3. If I upgrade the amp, will that make a significant difference with the factory JBL sub?


    Thanks a ton for your input guys, and I look forward to your responses!

    Thanks @Tundra14Platinum. I just contacted Tech12Volts. Looks like they have a sub replacement that "doubles" the bass without messing with the amp or anything. If that's the case I'll be thrilled with the quick-fix option!

    Ultimately you are right about replacing the entire system. For my needs if I can just get a decent amount more bass without going through major surgery I'll be happy. Really appreciate your help!

    I sound deadened the back wall and floor and stuck an Alpine 8” sub (with 1” trim ring) in the factory housing.
    Made a substantial difference for about $150.

    Dude that's what I'm looking for! A cheap fix that doesn't involve a ton re-wiring and messing with the amp. Thanks a ton for sharing!

    Ok so I went a totally different direction (still looking out for my budget though) than planned. And I LOVE it and wanted to share.

    But first a few fails:

    1. Order a 8" Kicker CompC sub from Amazon - magnet was too deep for the 2.5" factory housing.

    2. Picked up a Kicker 10" CompC pre-installed in a shallow sub box - still too deep. Now I'm pissed.

    More research, more research, etc. Do I buy a sub and install in the crappy plastic factory enclosure? Do I make my own box? On and on and on.

    Let me make this real simple for anyone wanting more than decent bass for under $450. Here's what worked wonders for me

    HARDWARE:
    1. Rockford Fosgate P300-8P. This is a 8" sub, amp and enclosure combo. 300w amp with a wired remote bass knob controller. I bought this and an amplifier wiring kit for $302.

    2. AudioControl LC2i. $100 at Best Buy

    INSTALL:

    Cut nipple off from the main wiring grommet at the upper right corner of the firewall.

    Push power cable from inside the truck through the nipple using a coat hanger and some tape. Once you see it coming out from under the hood get some pliers and pull the rest through.

    Terminate to positive on the battery leaving the fuse OUT of the inline breaker. Run the cable under the plastic cover in the floor to the back.

    Remove seats (small seat can stay). Remove plastic sub box and unclip the speaker harness.

    Install the AudioControl LC2i behind seat. Install sub behind rear seat. Both the sub and the LC2i can be grounded on the floor where the old speaker box was screwed in. I also pushed the sub back as far as I could over the factory insulation sheet. And I literally just laid the LC2i device on top of the sub.

    At this point put the fuse in the breaker at the battery and everything should turn on. It's that easy. I did this in about an hour and a half after work today and I'm no professional.

    You will have to adjust some of the dials on the amp and the LC2I converter to get everything dialed in after install. Once complete simply reinstall the seat and you're done.

    As for performance...wow....this little sub hits!!! I can't believe how hard this thing hits. Pushes a ton of air out of the ported box. This thing exceeded my expectations in all categories. I have not upgraded anything else from an audio standpoint. Factory head unit, factory amp and factory speakers. But I feel like I went from worst to first in under 2 hours today. Trust me this thing thumps!

    I did a ton of research, watched videos read articles, called local audio stores, etc. Nowhere in my research did anyone mention installing an under the seat style amp and sub combo with the converter. There were lots of other practical suggestions that certainly would have worked. However, I wanted to get this done for $400 AND get away from the factory JBL amp. This fit the bill, was an easy Install and added more bass than I need! Thought I'd share this in case you're in the same situation. Message me if you need more info!

    Sorry for typos - sending from cell

    You just plugged the sub wires into the LC2i?

    C96D4B3B-26D9-4A42-AADB-7B107DFE0FB9.jpg That’s what I would have looked into if I did not want the whole system replaced. I have one of them in my 19 Z06 what a big difference with my Bose system without changing all the speakers. It probably fits no problem.

    So what does the LC2i do for you? Is the sub the only thing that you plugged into the LC2i?

    I'm curious if anyone has tried fitting a 6" Bazooka tube behind the rear seats. I know its really tight back there but I think it might fit and I also think the stock JBL amp can push it with no problem

    Bazooka tubes used to come with their amp inside, no need to add. Unless they changed their design. Still don't know if it will fit.

    Some come with the amp others don't. They also have single or dual voice coil designs.

    I also went with @james@tech12volts. Used his plug and play harness to add sub and amp. Kept the head unit. Two JL 10's and 500w amp.
    PS- plug and play means I did not cut any factory wires, but did have to power the new amp. Have had a few people confused in the past about that.
