Hi, Well im looking to change my front speakers on my 99 civic coupe and well ive searched and found out that the stock size is 7". But I was wondering will anyother size fit with out any mods?

That sounds a little on the large side. 6.5" with a very shallow/small magnet should fit without any modification. Most aftermarket speakers are deeper and/or have bigger magnets, so you'll be doing some work to get them in.

 

They are 6.5" and it is hard to find the right one that fits. I ended up get the 5.25" and making an adapter plate out of MDF.
