Upgrading my front speakers, need help choosing an amp

Hello all,


I am going to be upgrading my blown rainbow speakers to the Focal 100KRS (http://www.focal.com/en/car-audio-so...es/100-krs.php) and I really really need some suggestions on an amp. My set up is currently:

2011 base speakers (no tweeters)
rainbow SLC 210(that will be replaced with the Focal 100KRS)
oem rear speakers
SWS 8" earthquake subs
JL Audio XD700/5 amp
JL Cleansweep


Any suggestions on an amp will be greatly appreciated. I prefer something small to conceal the amp but if that does not work out, I am open to a bigger amp. The amp I have now is pretty good for the most part but often enough, when the bass is strong, the vocals get lower

The amp you have now should be more than enough. Where do you have it grounded? Also how old is your battery?

I am not sure where it is grounded but the battery is still the first one so a little over 2 years.

So if you are saying my amp is good, is it my gains that need to be worked on?

Check the ground cable and see where its grounded to. Also what size of power and ground wire was used?

What is the gain set at for each channel?

You could rearrange your channels

Forget about the rear channels run the SWS of what are now the two rear channels one to each SWS and use the sub channel for a sub. Use 04 wire for your amp if you are not already .
If you are now running the SWS in series are they 4 ohm or 2 ohm .
