Hello,

I plan to add an external amplifier in my 2016 Sienna which has stock head unit amp, not powerful enough to properly manage the Focal speakers in the front doors.

I d like to install this external amp somewhere in the car, but before tearing town the dashboard, I d like to know if someone already found a good location around 10"W x 4-1/8"D x 2"H not too far from the head unit, for an amp like this :

thank you

Will it fit under the driver or front passenger seat? On a Lexus sedan I had, the factory installed audio system amplifier was mounted on the floor under the front passenger seat but it was hidden and protected by a hard plastic cover that also directed air flow from a floor vent.

I installed a similar sized amp (Rockford fosgate PBR300X4) under the front passenger seat and fits nicely. Enough room around it for cooling and no probs with performance so far.

Ton of room behind the glove box. To access, remove the passenger side threshold plate, kick panel, and glove box/trim panel assembly. Should take about 5 mins to remove everything to access the area. Check out the picture below for the amount of space there is.

That's an interesting idea, although it looks like it would need to be mounted vertically which could be more of a challenge. If it fits under the seat and you don't mind running wiring to it, another advantage is having easier access to change settings, troubleshoot if there are future issues, and to change it out if you want to replace it later. Looks like you could put a larger amp behind the glove box possibly though, if there is a way to mount it and still get sufficient air flow around it.

If I discovered this before, I would have placed my amp behind the glove box for sure.
lot of free space also under the dash.
I finally placed my Match PP82DSP https://www.crutchfield.com/S-9PLXtrYkZ0M/p_975PP82DSP/MATCH-PP82DSP.html in the bottom of the central box between from seats.
I had to run all head unit cables and speakers cables also there.

I wired a dedicated power cable from the car battery to the BOX and under each seat.

I separate the dash speakers wire and the front doors speakers wire, so I use the Match AMP DSP as a 6 channel AMP, plus a ground zero 10" active sub under each front seat, controlled by the DSP.

The thing is the Match DSP needs to be setup with a computer via USB.

good to know, I put soundproofing cotton material in all this free space under the dash, and trust me, the engine noise almost gone. the car is nothing compare. probably the most noticeable improvement for few dollars and can be done within one hour.

What kind of enclosure are you using for the 10" subs that fit under the front seats?

So using high-level inputs, where are yall catching them. I want to add a single sub and a small amp to run it. Will mount the amp behind the glove box.

I'm running an NVX MVPA-1 (a beast of an amp in a tiny package)

Conservatively rated at 300w x 1 @ 2ohms, it actually dynos MUCH higher

Priced at under $100, it's the most bang for the buck amp available


Easily fit under the driver's seat with room to spare

comment and a question:

First clean install, now you've sent me back down the nano amp rabbit hole. Once upon a time I had a Massive Audio NX-3 under the center console of an 04 Yukon pushing 2 Memphis 12's that definitely did the job.

Second, is that the remote gain for you sub on the side of the seat?

Thanks

Yes, I'm using an AudioControl LC2 with a control knob

The push buttons control the OBA Compressor (ignition/pressure switch sourced) and toggle between the dinky factory horn and K3 Train Horns

Oh she knows better than to touch any of my $h!t lol

First time she layed into the horn on my golf cart, she nearly wrecked it :ROFLMAO:

Also hidden in plain sight are these momentary switches that control the rear bumper squirters, tank drain solenoids (air blasters) tube flood
