Adding a Subwoofer To 05' 4Runner JBL Sys.

[bzizzi]

I just added a Subwoofer to my stock JBL system in my 05 4Runner Sport and I upgraded the speakers ONLY in front and rear doors.I tucked a RF bd 500.1 mono amp under the passenger seat with a remote bass volume control mounted up front.I also swapped out the JBL 6.5" speakers in rear doors with MB Quart QM160.03KX's and MB quart PCE 5 1/4" componets sets up front.I did not want to make a big project out of it with removing existing JBL in dash changer and amps and rear seat audio that my kids love.The stock JBL amps seem to have enough power for the quarts.I used a JL 10W/6 v2 in a custom built box and disconnected the factory sub.I used a Audiolink Power Link II for a low level signal to the amp.To my suprise it sounds awesome the bass really hits hard now.And best of all I still have the in dash changer and rear seat audio with headphones.I have a Homelink kit ordered through Toyota parts and am going to install VIP RS3200 security system and finish it up with a Lowarence I-way 500c navigation system.
