Ok so to start off i have an 07 335i with navi and a nice audio system but it does not satisfy me, i have always liked a little more sound and a nice deep bass in my cars. My first thought was to get a better amp and install it to the stock system, but being that my girlfriend bought me a kicker 750 mono amp for christmas, i now have more budget space so i bought the JL audo 12w6. Originally i was gonna get the stealthbox but it is just too much $$

So my question is will this setup sound good in our cars? a jl audio 12w6 with a kicker 750 amp...

and my other question is will i be able to do this while connecting the kicker amp to the stock speakers to give it a little more power... and how would this be done?

i am a long time viewer of this forum but just became a member! thanks for your help

Id also like to know a little bit more about technic's harness and how that works?

[kaigoss69]

Technic's harness hooks up in between the OEM amp and the OEM wiring and allows for the connection of an aftermarket amp without any splicing or cutting of OEM wires. Also, he provides an LOC which takes the hi-level signal from the amp and converts it to low-level which is what the input of your amp requires. A mono amp can only amplify one channel so it is only for the sub.

so basically what i was saying is not possible? i would need a whole other amp for the oem speakers?

and i was also wondering if the 12w6 with the kicker 750 is a good setup? will it sound hard in my car?

[d335ilove]

or maybe if i would change the amp to a duo channel?

the point of the above thread the OEM speakers won't take much amplification at
least on the HI FI system

[d335ilove]

so your saying there really isnt a point in getting another amp for the OEM speakers and under seat subs?

[ctuna]

Not without changing the speakers to something that will handle the power and
make good use of it. I think numbers show that you will blow the OEM speakers and
you won't be able to get use of the full capacity of the Amp.

Technic lives in Florida you might want to go see him he can set you up.
My feeling is that you have to fix the weak points of the old system before
you can start adding more stuff , but thats my view.

[d335ilove]

that makes sense.
and yea i wanted to talk to technic first because ive seen him on alot of post and i know he lives in florida but being that i am new i cant pm him.

another question i have is do you thing the 12w6 will thump nice in the car ? because i constantly read that our trunks are too sound proof.. i just wanted to know from someone who has experience with systems in bmws

He must be having a vacation or something he usually responds pretty quickly.
There was another guy having the same problem in one of these threads and he listed an Email address but I don't know which thread.
