is the optional, factory sub for the tC powered already or is there an external amp for it? also - how does that connect to the factory speakers since there are no rca's

 

It's powered... but it's not terribly much.

It has a factory harness that you connect to the head unit and run through the car to the rear. That plugs directly into the back of the sub. It's cake, really.

The only reason I have it is b/c I got a great deal on it from the Classifieds here, otherwise, I don't think it's worth the money. Sounds OK, but you can do better for a couple more $$.

 

yea - thats what i was thinking ...but im having an issue with where i want to put an external amp. I wish someone mass produced one of the ones from for example ..crutchfield. where you can put a kicker or whatever you want it in becides the factory speaker

 

If you take it somewhere, they could do it. Could just splice into the high level inputs of the amp from the rear speakers. Some people also make adapters that have RCA jacks on them. Check ebay, some guy has some usually on there. Don't know how well they work though.

 

im not going to mess w/ the factory unit. I know its not going to be what im looking for and its going to be strained more then what its designed for.

 

Adding an external amp isn't going to put any kind of "strain" on your HU...

 

Yea it really wont. It doesnt go anything but get the signal from the hu to turn on. I had a high level thing on mine and it sounded alright. Look at the new thing jl has out. Its supposed to be really nice and digital

 

^^ the JL Cleansweep unit.... awesome product!!! naturally though $$$$$$
