Is dynamat a necessity?

If so which locations are key?

Where can I buy velcro strips to put inder my sub enclosure?

I am running my door speakers off of an amp located in my trunk...What is the shortest route to run the left door speaker wire without being near the amp power wire which I ran on the left side? Do I have to run it to the right side first?

 

Dynamat is a necessity only if there is excessive buzzing and rattling. You might find that you need sound damping in the front doors and trunk. You can get velcro strips at the grocery store or at arts & crafts stores. Running speaker wire near power wire won't be a problem because the signal is already amplified; it won't pick up much, if any, noise. Still, make a 90-degree cross if they have to cross at all.

 

you should not run PREAMP wires, such as RCAs next to the pwer wire. Thanx that saves me alot of work.

 

Yeah, the RCAs are the ones to be careful with.
