Will these speakers fit inside the existing hole and hole pattern in the door panels?
A shopper on Nov 10, 2014
Best Answer: Hello,

You did not provide any vehicle information, so it will be impossible to establish that. However, you can check with the two fit guides below, to see if your vehicle calls for any special adapters/brackets. Also, like all things car audio, a bit of homework on similar installs will go a LONG way.

My current speakers for my car are busted. I want to buy these to replace my current speakers. Do these speakers come with wires in the box?
Taylor b on Sep 19, 2014
Best Answer: Hello Taylor,

Yes, they do come with a patch cable w/ Quick Connects. Of which may not be used at all, it depends on the length of wiring available. Nevertheless, what you see pictured is what you will receive.

im replacing my speaker in my nissan sentra they have great reviews but how about the bass quality?
A shopper on Sep 2, 2015
Best Answer: There okay, All depends. they dont give off alot of deep bass which i like. then again, i like my music extra loud. but when i had them put it in, I found out that there actually the cheap Rockfords pretty much. if you just want a lil bass for when inside your car, theyll work. if you like it loud like myself, i wouldnt buy.

is a wire harness included with the speakers?

Best Answer: Speaker wires with the proper terminals were included. They were pretty long and worked great for my install.

would I have to use any type of booster if I hook up after market speakers to a stock radio?
A shopper on Aug 23, 2014
Best Answer: Hello,

Absolutely not; especially for Prime Series Rockford Fosgate speakers. Ideally, you want to eventually add an amplifier to get the full experience of the speakers. This is because OEM Headunit rarely give you anything beyond ~10w-15w RMS to each location [assuming non amplified]. Nevertheless, no 'booster' needed if you don't want it.
