Am a newbie to this forum but I feel I've alredy learned a lot just by reading lots of posts.
Amazing the amount of info here!
I need a little help with an install I'm doing on my Miata and am hopeful I can get the benefit of some of your expertise.
Want to keep the stock HU which is really pretty **** good. It is an in-dash 6 CD/AM/FM Changer made for Mazda by Matsushita (Panasonic). Am replacing the door speaker components with some CDT units and also am adding an 8" CDT sub. Unfortunately, thats all the room there is for speakers in this small car.
Powering is through a 4 x 50/100 amp, bypassing the internal amp in the HU. I have two issues I'm not sure about.
A) The stock OEM HU does not have a remote turn on for the amp.
B) The stock OEM HU does not have preamp level outputs so cannot use RCA cables to the amp.
What is the best way to hook up a remote turn on for the amp? I've read posts where guys are going direct to the fuse block and others have wired in a relay. Seems like a relay would be the safest way to go, but being a novice at this, I'm not certain how to do it. Would only want the amp on when the HU is turned on.
I have read that I can purchase line level converters to allow the use of RCA cables to go from HU to the amp and doing so will provide better sound and S/N ratio. It seems this would be the way to go but I have no experience with line level converters. What's a good brand and a good place to buy?
Will be using two channels for the front component sets in the doors, and will bridge the other two channels on the amp to feed the sub. Am I correct that I can use the rear speaker outputs of the HU to feed signal to amp for the sub. The amp has built in adjustable crossovers so I can control Hz going to speakers.
Sorry for this long post. As I learn more, will try to keep them much shorter.
Any and all suggestons and assistance will be most appreciated.
