bass for 2010 jetta sedan?

no a powered sub is usually a rip off

if you get a four channel dual amp from walmart its like 90$ and 2 dual subs (60$) i will really ad a lot of good quality cass to your music

you might want to consider getting a new head cause if you dont it will be a real burden installing an amp without the rca outputs an aftermarket head comes with

good luck

hope this helps

invest in a Line Out Converter(approx $10-20), and a good pair of rca cables(another $5-20). This will allow you to tap into the signal at the back of the radio, and convert the signal to a low level or RCA output. By doing this you will help to reject some of the noise that would be picked up between the stock radio and stock speaker. This will also allow for an easy hook up if and when you do replace the factory radio. LOC's are not big and can often be hidden behind the radio.

All the power wires no the amp will be ran the same with the exception of the remote turn on wire. +12v constant will still go to the battery(properly fused with 12" of the battery!), and the ground will still go to the chassis. You can hook the remote turn on to the +12v ignition wire behind the radio, or the equivilent fuse in the fuse box. I would not recomend hooking it up to the pwr ant wire on the stock deck as it often goes off when the radio is off, or cd is playing.

As I said, most cars have no issues with any of this, but cars with "PREMIUM SOUND" systems often do not mesh well with aftermarket equipment. Fords JBL or chrystlers infinity (And bose in darn near anything!) are often cause issues. Sometimes you can easily bypass this system(Ford), sometimes you have little choice but to rip it all out and start fresh(Bose).

i think you should get a jl w3 12 inch sub in a sealed box. that will give u some thump and be really clean and clear too.
