My h3 doesnt have the monsoon system Im installing 2 12s with an amp and I was told the stock head unit doesnt have the preamp outlets and I need to buy some sort of adapter to connect it to the stock radio.. I don't want to buy a new head unit so can someone tell me what it is that I need or send me a link to the part. Thanks any help is appreciated

 

I have the exact same question, i just posted it a few minutes ago... installing the same thing

 

im gonna go to best buy and see if they can help me, ill let you know

 

I got mine at best buy. About 20 bucks. I think its called a signal converter. It taps into stock speaker wire and converts the signal to RCA jacks. Mine has the factory amp so we used the wires going to the factory sub. We dont use the factory sub anymore, it sounded like crap.

 

Thanks and yeah blue let me know what they say

 

its called a "line output converter". its what gives you the RCA output to go to your sub amp. the only downside to using these (compared to replacing the factory radio with an aftermarket radio that already has sub control) is that you dont have much control of the sound level.
regardless that is the part you are looking for.

 

Does anyone know a decent brand indash.nav around 300 400 because i might just go that route i have been doing some research but really cant find much

 

You're probably going to be hard pressed to find a decent radio that has Nav built in for $300-400 unless you buy used.
Cheaper brands like Jenson or Valor may fit the bill but the quality is not the same as say a Pioneer (for example).

Heres a link to Crutchfields website for a Valor piece: http://www.crutchfield.com/p_077DDN8....html?tp=20212

 

I went to best buy and bought the converter they're talking about for $18 + tax. Best buy wanted $110 for the amp kit with power. I went to walmart and paid $25, If you don't have that yet. Also best buy wanted $100 to install it and he said he can only use the amp install kit sold there if he does it. I'm going to have a friend help me install my amp tomorrow.
