Aftermarket HU and sub installation

Recommended Posts

Hi everyone! I'm fairly new to this forum and don't know a whole lot about cars, but I love my caddy, its a 2000 STS, which I have now owned for about three months.

Now I have made the decision to install aftermarket subs (including door speakers if possible) and an HU.

I have 2 12'' 1000 watt volfenhag subs in a box and JBL door speakers

A kenwood amp

A 3.0 Farad Power Acoustik Capacitor

A Kenwood 7202 Amp

And a Alpine CDA-9851 HU

I've heard that installing aftermarket parts in a caddy is difficult with the Bose stock system and all, so any tips, suggestions, etc. would be much appreciated.

Thank you!

your original is a BOSE system? Excellent system.

Regardless of bose or not it is still a difficult job. I do not do aftermarket on caddys but someone will likely chime in that has done it.

Replacing door speakers is only downgrading them.

Its easy to install a sub, get a line converter that converts the speaker cable going to your factory sub on the back tray to rca that you can run an amp off of. Power cables only need to be about 5 feet long due to battery being under the back seat.
