Ive been contemplating this for a while now and just wanted to get all of your thoughts on the subject. I can get dual 31 band home audio EQs for under $200. the power inverter to run it in a car would be like $40 at the most. The only thing I dont know about is the cables to convert the rca from the deck to what the EQ uses would be. Now do you think it would be worth using the rack mount home audio ones over the car audio EQs? The car EQs are just so expensive when you compare the 2 its rediculous. I noticed a lot of people in magazines use the home audio EQs.

Rather than an DC-AC inverter, which could be noisy, consider a DC-DC switching power supply. You'd open up your EQ, discover the internal voltage rails, read the AC nameplate rating in watts, and then buy the appropriate switcher. Most likely ±15 volts, at up to around 1A will be the most common power requirements for a home device. Get one with an isolated ground, and you'll get no noise at all... They'll be around 60 dollars or so.
MANY catalogs have them, they provide switched leads, so you can use your regular remote lead and everything.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

The only times I see home ones used in cars are the ones that actually use 12volt in and just have an inverter on the powercord for home use. With those you dont need to use an invertor. All of those also were just RCA in and out. What kinda plugs are on the ones your looking at?

I was thinking about either one of those. haemphyst, Thats sound sgood to me but i have no clue what all that means. lol. Im not all that great with my knowledge of the iner workings of electronics. What you described sounds like a solder job, which is fine to me as long as its not too complicated. what do you guys think?
