I have spent last week installing a stereo setup that I have had planned for a little while.
My main things was to keep the boot free as i need the space for work tools and to keep the interior looking standard.
This is not a spl monster set up but aimed more at compact sound quality on a reasonable budget,so I have ended up installing a system based on the genesis profile stuff.
I went with a genesis profile 4 channel amp because it fits under the passenger seat and there profile 6x9 subs because they fit in rear quarters, with there profile components up front.
The amp is really neat and nicely finished with separate gain and crossover controls for each channel, it's also reasonably powerful giving 55 "genesis" watts to the components with channels 3 and 4 bridged to give the subs 150 "genesis"watts.
There p69 subs come in 8ohm and 4 ohm and they quote that there the equivalent to a 10"sub.
I brought the 8ohm pair and wired them in parallel so they receive the same signal and get shown 150 watts not 55 each.
I installed them by making a 18mm mdf baffle the same size as the hole in the metal and cut the 6x9 shape in it.
Then i bonded the mdf baffle to the metal panel using p40.(my car now smells like a tvr)
The p69 subs were designed for the new mini and to go in there stock speaker place.
They apparently work better in an inclosed space,so in the mini they sealed the rear quarter's which join the boot with expanding foam.
so i did the same using the piece of foam that was all ready there and sealing it in with expanding foam.
I also used sound deadening on the inner and outer off the rear quarter and blocked all the holes with it to make a sealed inclosure.
I am going to have to sound deaden the rear quarters more as i am still getting rattles,I found the xx song fantasy a good test, j christ that bass is low!
The components were straight forward,I used sound deadening on the inner and outer skin covering all the holes to make a sealed inclosure out off the door,I wanted to bond a mdf baffle to the door as recommended generally and also because the mids are close to the windows when there fully down, but i want to keep the stock grills and i think the cones would hit the grills if I spaced the mids out.
The tweeters are mounted in std place using the guide on the forum,probably not the best place for sound quality but a compromise as I want the interior to look standard.
My head unit has not arrived yet,but i am getting one with iphone control and bluetooth so I have run the lead so I can dock my iphone in the centre console compartment.
I just drilled a hole in the bottom of the compartment and stuck in a piece of mdf so it lays at a 45 degree angle.
It's not the best install but it's quite simple plus the hole can be covered up by the little rubber matt if I ever want to take it out.
Since I have brought all my gear, genesis has gone bust
so your struggle buying there stuff in the future,but it does come up on ebay sometimes and in fact I brought all my speakers off ebay second hand but new!
I have actually spent only half off the rrp buying second hand or in the sale stuff as i did not want to spend £1000 on a car stereo!
Hope some of this is usefull!
