I've been reading the forums for a few days now on different set ups... Avincar being one of them but I guess the kit is no longer produced. So I wanted to pick up speakers but worried about some not fitting or being to deep etc... So basically I'd like a couple suggestions on speaker combination set ups for my 2005 non Nav Tsx.
I'm mainly looking for sound clarity and some good tight hitting bass (best/most bass i can get without a sub). My goal is to keep the stock head unit, and likely not run an amp. I'm willing to spend money on the best speakers my stock HU can handle. I mainly listen to Soft/Hard Rock and some Metal and R&B.

Please list your suggestions and why you prefer that particular set up. Also anything else I might need like adapters or heavier gauge wires etc... Thanks fellas
