Does my tundra have a factory amp or does the HU power the speakers?

    So I’ve been looking to adding a subwoofer and I’ve looked and looked over threads to help me find my stock amp but no luck. It’s a Non-JBL. Anybody have any idea?

    Looks like double cabs can come with one or not. If it has one its under the passenger front seat.

    If you have an SR5, you have an amp under the front passenger seat. The headunit powers the shitty speakers on the dash. The shitty amp powers the 4 shitty speakers on the doors. You will need a sound processor or LOC at a minimum to add a sub and amp.

    Hey @Danman34 - I’m in the middle of planning the replacement of these OEM amp and speaker components in my truck. Do you know any of the specs on the factory amp with this very distinctive brand name ‘Shitty’?

    The specs?
    Sure, it produces minimal wattage to power OEM 2-ohm door speakers.
    It's a POS.

    21CBB347-D751-4220-AD0B-F8726124EA25_zps_716c19ddf6955de56e203764ad16d8d9538f2ef7.jpg D366271B-A6F3-49DC-BA1A-E5DDA9144B25_zps_d46f0338ecba8b955744a85580c9aa3de8426e36.jpg

    Use one of these and you won't have to cut any OEM wiring.

    One more thing;
    Buy the best front door components you can afford.
    Get the JBL door sails and mount your tweeters in them.
    Disconnect all 3 dash speakers, just unplug the side speakers, they feed the DVC center.
    And don't forget you'll need spacers/adapters to fit your aftermarket speakers in the doors.

    Why waste money on new sails? Just use a hole saw and drill holes in the ones you have.

    Because I want to be pretty and flat.
    The JBL sails angle the tweeter more towards in the inside of the cab.

    Stock sails have a curve to the face.
    A flat tweeter mounted in them looks like shit..

    The Infinity tweeters I have are adjustable. I have them angled towards me.

    I'm overwhelmingly and ecstatically excited that the stock door sail met your needs.
    They didn't meet mine.:oops: :thumbsup:

    I recently replaced the amp under the seat and the door speakers and added a hideaway sub. The upgrade was well worth it!

    I kept the factory head unit and I have the amp set for "high line level". Is that the right setting if you reused the factory amp input wiring?

    I ask because I have a bit of white noise when the volume is low.

    Yes that is correct..
    Make sure your amp has a good ground.
    Make sure to get good ground contact to an unpainted surface.
    If I remember correctly the stock amp had its own ground bolt to the body.

    Make sure you used a big enough power wire gauge from the battery for your amp.

    You might need to make some gain adjustments on your amp.

    Look the this and see if it helps..

    I've learned a lot from him and his videos are well made.

    I went ahead and paid for his consultation services. I used the Crutchfield tools and somehow got the right speakers, but the amp and subwoofer, I was completely lost. He was able to get me straightened out in a day.

    Thanks for the tips. I may have an issue with chassis ground of the amp being tied to the same place the ground cable is connected.
