2007 Avensis stereo upgrade

[samuelodog]

I have a 2007 Avensis. I want more bass in the audio. Is there an easy aftermarket upgrade I can do? I have an underseat subwoofer, but I don't know how to easily install this in this car. Any ideas? Many thanks

i did this to mine with a PIONEER GM-D1004 4 Channel 400W Class-D Multi Channel Car Amplifier

id say you could do away with the amp and get a nice pioneer andriod touchscreen headunit and with dab+ radio i would advise and that speaker upgrade be a great job. the Speakers came in my car were very cheap looking

You just did the amp? Was that easy? What difference did it make? Or you did amp and more? Please explain, thanks

i did the Speakers just like the link i send you was a great job sound compared to the Speakers that came with the car and well the amp i put in tbh its better than stock but for the Speakers i put in im half thinking i wish i went for a bigger amp i am going to sell the amp off and get a bigger amp for it as the music is good from it but just for the speakers i put in maybe that wee amp i put in is a bit small i bought all my things from dynamic sound i sent him a message as i got my speakers from him also and ask him what is the best amp to use with my speakers setup and headunit

when you add all those, put dumping material and glue everything well because all the plastic parts doors dash and so... will start to noise you while you drive. and do it ones well instead of finding yourself dealing with annoying things all the time...

That is nonsense. Couple years ago I upgraded Speakers and added also little amplifier and nothing changed at door/dash creaks.
It is different if You add million inch subwoofer and million watt amplifier to trunk but that speaker/amplifier upgrade gives only better sound quality.

i upgraded my car Speakers etc and i had not problems either . i put in those sheets of Sound Proof Deadening Pad  in the doors before i put on the Speakers its a great job
