When I first started searching for amps, I wanted a 5-channel, for my speakers and one for a sub in the future. In my research, I discovered that 5-channel amps were generally more money for less power. Also there are different classifications of amplifiers, AB is a good amp for driving speakers, while class D is the best bang for your buck as far as subs go. I ended up going with a 4 channel, and I'll buy a dedicated class D amp for my subs.

Guys, I´ve also changed stock sound, currently I´m playing with JVC head unit, front compo system is from ///Alpine Type S (basic but tweeters are good) and sub Helix P10 in closed baffle-board. These hang on Audison SRx 4 (means 2x 50W for speakers and 1x 170 W for sub - this is way too low but new apm will come soon just for sub - at least 500W RMS should be fine).

First thing I´ve made - new cables for amp, power on left side from battery to the amp :




Two pairs of RCA´s on right side to avoid interference :




Back seats were removed to have better access, rear speakers were just removed, I´ll have nothing there :



After this I´ve put some "sikadamp" damping on the front doors, made wooden adapters for speakers, made 15-l baffle board for subwoofer and installed amp. Pics will follow later, currently I have to finish position of tweeters and find some better place for amp.

Sound is good but amp for woofer is not sufficient, also unfortunately mids are kind of low but I´ll work on it (new head unit is needed). Maybe I´ll change also front speakers and will add processor .. once you´re in sound madness, you cannot stop.

so a lot of people are suggesting 2 amps to power speakers and a sub due to sound quality issues.

Has anyone tried one of these out?

alpine pdx-5

yeh those PDX look alrite, alpine actually puts that into a pack in the catalogue i have.

So, as promised, some update on current situation :

A) New head unit /// Alpine CDA-9886R installed



B) Doors - my opinion is, that damping is mandatory if you play front speakers via amp, otherwise there will be lot of unwished sounds coming out from the doors



C) Trunk upgrade, currently only one 4-channels amp but there will be another one for sub, will add plexiglass and some neons for show





Safety first In case of accident I don´t want to have my sub on my neck, these screws seems to be not sufficient so I´ll change ´em.
