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

Recommended Posts

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

The ppi ion series are very cheap and do rated power.

too many freq at once, burn the coil, we all know, over 40-50hz, its all coilburning material.

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.

yeah 900.4 very strong but u missed out on smaller rf 4 channel sale last week on amazon was $78.. the ions are about $130-$180 520 or 1000 depending where u find it very very small amp but like popwar said do rated power just no wasted space inside..

No I have a 5.25 in each door and the 6's in the back.

 

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. @Jeffdacheff has a solid background when it comes to stuff like this.

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.


09 Sienna Subs : Four Team Ascendant 18s......Sub amp: Two Taramps 15k

Headunit: Pioneer 80PRS......Mids/Highs two pioneer gm 8604 bridged, one at 4 ohms bridged one at 2 ohms bridged, one ppi 600.2 for tweets.

Front stage: Two PWX 10s per door midbass only....... PRV 6MR500 midrange....... Massive CT 2 german tweeters.

320 amp Singer alt....... 1 group 34 under the hood 6 group31 agms in the back 560 amp hours total.

My vote is for the Rockford Amp. Even their basic stuff is built well. We put a RF Prime series 5 channel in our hot rod. Was a little under rated according to its birthsheet.

Have you or do you know anyone who has bought amps at Amazon Warehouse? I worry about warranty and such but might do it. Odds of a Fosgate blowing up on me?

If you're worried about warranty buy from an authorized RF dealer. Odds of it blowing up are slim as long as you set it right and don't abuse it.

TY. I am thinking of reasons a customer may send an amp back to Amazon and it is probably just that they were not happy with performance I guess

Any of you guys ever tried the Punch compact? To go under the seat I may need something like this, not sure though of this below vs the Prime 250x4
