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[/B].

So you kept the stock headunit? Did you have any problems replacing the front speakers? I have a blown speaker in the front right door of my dad's Sienna, and I can't seem to get any straight answers on what I can replace it with.

From my understanding its a 2ohm speaker. Anyone have any suggestions?

The reason they are probibally 2ohm is that they are hooked in parrallel with the tweeter,my quarts are 4 ohm but run through a crossover and they sound great.a factory system usually will not use a passive x over for there seperates just a capicator for the tweeter and run the woofer at full range.
This is a cost saving method for them.I will post pictures soon,I also added
a subwoofer volume control knob in one of the knockout plugs in front of my console it works perfect and looks stock.I can dial in the amount of bass I want.I also noticed that the rear door speakers have a 200hz bass cut off
at the factory amp,so if you replace them dont expect too much bass from the rear door speakers,just mids and highs.I had to make a tweeter bracket
for the front doors,just unbolt the existing tweeter and trace around it to make a template,I used 1/8" steel and painted it black,for the 6X9" front doors I purchased adaptor brackets from crutchfield and they work great.I used 5 1/4" speakers.,you would not believe how much better it sounds
just adding a sub with volume control.Even with the factory speakers,you probibally blew the front 6X9" because you turned the bass all the way up
on the raido to compensate for the week factory subwoofer.If you want to try this I can tell you exaxtly what to do and what to buy.I have the JBL six
disc in dash changer with rear seat wireless system.

I have a 04 4runner with the in dash 6 cd changer JBL system. I want to increase the bass and overall sound. What did you install and how did you do it? How much did the whole thing cost?

I noticed that my rear door speakers are very low and don't know if they are blown or what. My tweeters in the back play louder than them. The 6x9's sound ok up front but feel them stressing with the bass turned up. I have to turn the bass up because I can't hear the bass from the factory sub.

I don't want to to change the unit or the amp just the speakers if possible. Tell me what I need to do because I hate rockin out to distortion!

Can you also send pics of your sub and new speakers?

How did you run the audio signals to the amps / new speakers? Did you use a high to low (speaker to rca) converter coming out of the factory amp to the aftermarket amp? How does it sound? Which converters did you go with? You only have the fact amp powering the rear door speakers, right? Just curious, but why didn't you go with 6-1/2s in the front doors? Personal pref?

So don't the speakers sound a lot quieter going from 2 ohm to 4 ohm speaks?

Hmmm. Sounds interesting.... May have to try it.
