Hey guys, new here. Couple questions;

I just bought a 10 tC with the base radio and the 6" pioneer sub. I want to upgrade it because its pretty muddy and gets distorted at higher volumes. Anyone know if there is another 6.5" I can throw in the factory box? Or how i could go about using the wires back there to hook up an amp? Someone told me I can just use a line converter with the 4 wires back there and the one wire for the amp turn on, just run a power and ground.

Can someone shed some light?

 

Before spending the money, have you tried changing the audio settings? Like SSP from Neutral to Hear or Feel; or changing the setting from tC to xB or xA? When I got my tC, it was set to Neutral and tC, and it sounded awful, muddy and quiet. But if you change your SSP and car sound settings, they will sound much better. Try this before thinking of spending money

 

I did. I played with all the settings before hand. Right now I think im just going to live with it and just cross the upgrading road when I blow it out or whatever. The trunk space as is, is kinda small so Im reluctant to put my box back there anyways

 

quote from Crutchfield-"The Scion stereo system could be augmented by an optional factory subwoofer. If present, it’s located inside the car’s cargo area. The component is comprised of a 2-ohm, 6-3/4" subwoofer powered by a 35-watt amp, and is integrated into a molded cavity to the right of the spare tire. As a result of the integrated configuration and low-impedance design, replacing this woofer is likely not worth the effort. If you want to replace the woofer, you should also replace the amp with something with more power."
probably be better off just replacing the factory radio with an aftermarket, because it will give your front/rear speakers better overall sound with the sub...
there are 6-3/4 subwoofers that can replace the factory sub, brands like Kicker or JL, but you would need to fabricate the connections with the amp into the factory harness...or just get a different amp & sub box setup to fit in place of the factory box...either way, I hear you on the limited trunk/cargo space, good luck with whatever you decide...

 

An upgrade won't necessarily eliminate mud. Sub-frequency is limited but demanding. My sub filter is set at 20Hz to 200 Hz which is great for rock. Hip hop might be better at 15Hz to 150Hz (which might require a larger speaker enclosure and or different port size/depth.) Even a matched range between sub amp and speaker enclosure can sound muddy if the artist recorded frequencies outside your hardware's range.

 

The sub I would be putting in to replace it is a 12" mmats p3.0 with an alpine 750w. It was out of my last car. Hits Hella hard and sounds good with almost anything. Just very large.
