Need an amp for rainbow slx230s

[jakescanes1234]

I recently installed some rainbow slz230 components into my saxo
along with a jbl sub and amp.
The subs 250rms, and the amps 240rms.
so thats all dandy.
BUT - the speakers are rated 20rms upto 80rms.
and atm there running off 17rms from the headunit.
they have next to NO midbass but are very clear and im impressed considering how underpowered they are.They do sound very tinny and the sub is faded all the way out to get an OKAY balance but its very bass orientated. So the time has come to put them too good use and find an amp to power them.
so opinions please. ill pay for quality, not on a massively tight budget. but no more than £200. less if still good stuff.

Thankyou guys.
