I just had the Pioneer TS-D6902R 6x9 two ways & Pioneer TS-A1674R 6.5's installed on my '08 Taco double cab with the stock non-JBL HU. Huge improvement over stock speakers! The music sounds clearer & you can feel the low notes better. I have the GROM IPOD kit installed so that I may play my IPOD.
Now, I don't think I want to add a 10" sub with an amp anymore like I had on my previous vehicle, an '07 Saturn Vue with the stock HU. I've been on the fence about it since I use every ounce of storage space in the truck & the interior space is smaller than the saturn Vue. I may just opt for a double din Pioneer unit. The tech who installed my speakers has a double din Pioneer in his truck with no amp at all & it sounds awesome & twice as loud as mine but it's an older model. I don't care for a DVD player since I don't watch movies in my truck & Navi is OK but not necessary. I want it to be able to play, (& also charge like my GROM kit does), IPOD's, have blue tooth, & have more power than my stock HU but not be too flashy & I would order the Double Din dash kit from ebay.
Also, anyone know why some songs sound louder than others on the IPOD. My IPOD is almost 5 years old. Time for an upgrade? My 2 boys get all the new stuff! LOL! I did the sound check thing on the IPOD but nothing changed.
Thanks in advance for your input & advice. You folks are extremely helpful.
