Alpine psu300-tnd amp and powered sub

I have a 2014 SR5 with non jbl system. After six years I decided to upgrade my system. I was tired of no NAV(I used a portable garmin as the phones wont work were I live and go) I was also at the end of my rope for glare on the factory radio and the fact I had to tip my prescription polarized glasses down anytime I wanted to see my screen. I did a lot of research and was about to replace my whole system speakers and head unit for a Kenwood. It was about 3000 dollars give or take but as a DC no real good options for a sub. I can do some stuff on my own but figured I pay the local shop. Then as luck would have it a non JBL nav radio came available here. I decided since I really like to keep my inside as OEM I would just get the head unit and figure the radio glare and sound out later. I looked at a plug and play from Taco Bell but decided against it. I found nushield screen protector that fits no trimming and completely gets rid of glare and I can see it perfectly with my sun glasses. So the sound of course needs a small upgrade and I found the alpine psu-300tnd. Now I got it for 650 with an alpine 100 dollar rebate. While that might sound like a lot as you can just buy the little 4 way amp and the 8 inch powered subwoofer separately for a few hundred dollars less I say who cares. It comes with tundra specific harness and mounting bracket. You just take the passenger seat off remove the non jbl amp and replace it with the alpine set up. Having the sub under the passenger seat is great since putting a sub under the back seat was not an option for me. I didn’t have to replace any speakers and it sounds great. Now if you live and breath music this prob ain’t for you but on there other hand you can still use the setup with aftermarket speakers and HU if you want. I know this is long winded but I could not find a lot of info on this set up anywhere. Side note if you are still reading and are interested, if you don’t set the dip switches exactly as they say or you decide you want the sub to hit harder (which it can as I tried it out) by using the RCA set up it will not work correctly. You will get anything from all speakers will be playing right channel to no rear channel. Now if you you you are still reading and don’t want this kind of set up well who’s fault is that.

 

hi, thanks for your post, is it difficult to install? ive seen a post on how to wire it and it need to take the center console or ac unit and radio to unplug some wires and plug this one to it

 

While yes you have to take out the radio and a/c controls and remove some trim along the floor to hide the wires it is a straightforward. You have to wire it exactly as it says in the instructions as there are some options to hooking it up and there is pop of the sub when ever you turn it off but that does not bother me.
