Q
will these fit on a 7 series rear deck section?
[ Jose  Sep 17, 2022 ]
1 answer
A
Greetings Jose, and thank you for your question. I would need a bit more vehicle information. Year, make, model, etc.
[ Thomas J.  Sep 17, 2022 ]  Staff
Q
Are these suitable for outdoor use on Harleyâ??s.. waterproof?
[ Scott  Jun 03, 2022 ]
1 answer
A
No, these are not marine/weather rated at all. The Polk DB series or MM series speakers would be more suitable for a Harley. Also, we have some custom systems for a range of Harleys. If you input the year and model on our "Find what fits your vehicle" page, that's where you can find possible options!
[ Dylan  Jun 03, 2022 ]  Staff
Q
Would these be plug and play with a 1999 7 series or would i need to do some rewiring?
[ Fredis  Jun 01, 2022 ]
1 answer
A
These speakers will be drop in replacements for front and rear doors in that 99 BMW 7 series, yes!
[ Calvin  Jun 01, 2022 ]  Staff
Q
Are the 75 rms for each speaker or for both ?
[ Alberto  Mar 04, 2022 ]
1 answer
A
Each speaker can handle up to 75 watts rms each! I have mine running off of a 2001 BMW 530i Business Cd system which says it's giving out 20 watts to each speaker and they sound good but I have a 4 channel amp that I plan to hook up to them and it's rated at 75 watts rms x4 so I can't wait to hear them powered by this amplifier!! These Kicker 5 1/4 coaxial speakers are a great choice bc of their high sensitivity they are very adaptable to any power source!! I hope that clears up any confusion or other answers. If not ask me I have been doing car audio for over 25 years
[ PILAR  Mar 05, 2022 ]
Q

Q
Are these water resistant?
[ Derek  Jul 21, 2020 ]
1 answer
A
I believe they are not but I had left all my windows and my sunroof open and it poured rain extremely hard overnight and the next morning I wen to my car which had puddles in it so I thought I was doomed but to my surprise when I turned on my stereo all 4 of the Kicker speakers were playing just fine!! It has been 2 weeks since the rain and they are still sounding amazing!! These speakers sound great considering I am running them off a factory '01 BMW amplifier with the other 6 stock speakers!!! I'm ordering a 4 channel amp so I can really make these speakers crank, but even as they r powered now they sound pretty loud and clear!!! They r a great choice for 5 1/4 speakers!!!
