I have fusion encounter spits in the doors and just installed speaker brackets in the roll cages (ebay USA) for with fusion reactor splits, running a fusion reactor 4ch 90w RMS, thought it would be better then it currently is not much base from the rears even though they are more powerful splits?? but am going the seal it with silicone in the cracks cause lots of air is poring out of them, think this will help with base?? Your imput would be great cause got a more powerful amp and splits then the encounter stuff and am a little disappointed, starting to wish I did encounter stuff all round now, or maybe go for reactors in the doors too so can run them both at the same gain.
