thanks for the advice. I am in perth WA unfortunately.

The reason for the RF 3sixty.2 is that its got some decent reviews & well i really havent looked into the others yet. I will do some more research.

Ill start investigating monoblocks and get back to you aswell.

Just remembered that my brother has like 2 sets (ie 4 x 6.5inch) sound stream splits sitting under his bed. Brand new unused. I think he paid about 800 a set so they should be pretty good speakers. He got into bikes so is selling his car , so if i can get my hands on them thatd be ideal. The only issue is that from memory the magnets on them were pretty massive , big bulky silver things ... Probably gonna need some kind of large spacer.

Re sound deadening ill use a combination of CCF & SD.

Quick question , if i purchase a DSP does that negate the need for an LOC?
