Is there any decent manufacturers of these? Had my Cd player ripped off last weekend (2nd time in 2 years) and I'm just going to throw in a stock 5band eq delco in. I'm still going to run a large amp and have it bolted/chained/welded in, but is there a decent way to do this? I had a stock delco in my '87 Fiero GT with an Alpine amp a few years back and used (I think) a DEI line level adapter, but it had a little "noise" in it. Just wondering if there's anything better. Wanting to have 4 RCA's when done. TIA!
