    How much needs spent on a 4 ch. amp for four components?

    Got my son a sub box and amp but his components are lacking. He has some basic Fosgate's, (2) 6" and (2) 5.25. I saw some Fosgate 4 ch. amps for 100 or so, if that excessive for a basic setup? Speakers are 40-50 RMS.

    No, not at all. Sound deaden as much area as possible and a good amp for those would be ppi 900.4

    Thanks. What's economical for sound deadening? It's an Acura 03 RSX. The rear 6" are in sort of a baffle but front doors are not

    Stinger roadkill or NVX deadener seems to be the best bang for buck out.

    I wouldn't worry about the back/rear since most of your sound comes from up front.

    We could try that. I would have to be careful, the front are only like 40 RMS.


    I forgot to mention my son has a Kenwood Kac M1804 4 ch. amp. He got it for like 30 bucks of his buddy. It is a marine amp I think. May this is causing the speakers to sound "shrill"? It is hard to explain but they just do not sound that good, to me at least. Looking to get a thick, warm sound but just is not happening.

    Could the head unit cause this? he has one of the basic JVC units that was around 70 bucks.

    That's some cheap stuff he has. I wouldn't expect any of it to "sound good". In order to get some comps to sound good, you need a good decent set and about 2-3x power than "HU power". 40 watts isn't near enough to make them shine. A better HU too might be needed too. @Jeffdachef f has a solid background when it comes to stuff like this.

    Cool I will check that out thanks!

    I did some reading and searching and found these 2 i was considering. The Alpine owners are REAL happy with the performance on using 4 components.


    Alpine KTP-445U

    Rockford Fosgate R300x4

    Both are around $110

    absolutely can. minimum requirement for a head unit is 24 bit dac, 13 band or higher EQ, 4 volt pre-out, time alignment capabilities. Its the amp and also your overall install. You cant just toss speakers onto a door and expect them to sound good, you need to turn the door into a proper speaker enclosure in order to get any warm sound.
