It does not matter if you use a one or two channel. As long as they are 2 ohm stable. Make sure not to crank the gains too high or you could blow the sub.

The adaptors I use for connecting to a factory deck is the PAC PSI2 adjustable line output converter. Have had great luck with them, probably installed 100 this year and not one came back. We sell them for about 23 bucks. Avoid a really cheapo one because those can have problems. You can find those at almost anyplace that sells car audio.

And remember, for a one channel amp use a DVC sub with dual 4ohm voice coils. with a 2 channel you want a 4 ohm SVC or a DVC with dual 2ohm voice coils. Once you get the sub/amp combo post if you need help wiring it up. We are glad to help.

Take care.

I have a 01 Audi A4 and i want to run my wires but i have a problem. The back seat folds down but there is still about a 6" section between the seat and door that i cant figure out how to remove. I tried to just pull it but got scared that i was going to break it. Any help would be greatly apreciated.

On most vehicles you first need to take out the bottom of the back seat and then there will be a bolt on the bottom of that small section then pull upward (towards the roof) and it should slide out easily. if not some also bolt from the trunk behind all the trunk liner.

On the side of the seat there are the leather bolsters with the metal bars that the seats lock into. Unscrew the bars, pull the bolsters off and this is the best way to run your wire's into the trunk on these vehicles. Dont really have to take backrests of but if I remember correctly they lock into a bar in the middle section, fold seats down look in lower mid section and that should be the trick.

I cant find any wire diagrams for an 01 A4. I need a diagram for the stock symphony radio and also any diagram needed for a remote start. Thank you in advance for any info you can provide me.
