Just curious, where are you guys hooking up your amps? Where is the exact location of the connection, is it just a standard L/R, RCA audio out jack. I assume its behind the head unit in the dash.

It's a lot more complicated than that. There are lots of threads on how to do it all over this portion of the forum.

1 search a minute isn't too user friendly though, at least when your at work. That would be great if anyone can help.

your gonna need a line output convertor or a high level input on your amp

Thanks man. Looks like the my best option would be too run a quality output converter right behind the OE head unit to an amp in the trunk.

I'm thinking about upgrading the 8" and keep OE placement/looks/trunk space. I've read quite a few threads lately. Seems like the Kicker 8" from Crutchfield is good deal, even though a mounting adapter is needed. Any opinions on the Kicker so far?

I took the signal after the factory amp (giving me a nice, high signal) and ran that to line out converters (2 - 4 input devices needed), then to the amps.

This is the best route if you want to save money, but if you want to spend a little bit more have have better quality audio, drop the LOC's and get an AMP with high voltage inputs.

I know I sure have more to read on the subject. But, I thought you get a better quality sound by using a quality converter nearest to the source, to prevent noise. I would much rather connect to the OE amp to another amp.

Thanks for the comments everyone.

Any quality amp brand/model in mind w/ high voltage inputs? I was planning to get a 1 channel Alpine, just for the sub upgrade.
