Single Amp for all?

Hi everyone, I'm new to this forum, and I have a question for anyone that might oblige. It has been recommended that I use an RF amp to power my whole system, due to space constraints and preference to keep the vehicle in [close to]factory condition. I am no pro but this struck me as a bit strange because i had never heard of this before. my equipment: Polk db 6.5" component system Polk db 6.75" coaxial Alpine 9847 deck MB Quart Premium 12" 500w@4 Ohms to be run with a RF amp [i can't remember the model] 800watts x 2 channel anybody know what this bloke is on about? thanks

i know rockford makes a 5 channel amp maybe this would be better suited.

Unless your installer is recomending using head unit power for your main speakers and an amp for subwoofers.Support the12volt.com

A single 5 channel amp might do the trick if you get one with sufficient power output to the 5th sub channel, but most of us would use a 4 channel and a mono amp.  Is it possible that you told this (salesman?) that you were on a limited budget and had no room?  Perhaps he was thinking of powering the speakers with the head unit?  Who knows?  And "factory condition" can always be reverted back to, in the end.  Get your system the way you want it...it's your car.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Thanks guys for replying. Installer was serious about configuring a 2 channel amp to power the whole system. stevdart - Yes I told him I am on a budget, he checked my space and said that he could power it all on one amp and it is my preference to stay close to factory btw. I drive an 2005 Volkswagen GTI and the front seats have a large housing for the mechanism that raises the seat for rear seat access. so no amp will fit that I have seen. I think he wanted to do passive crossovers and maximize power to the sub.(?) Any idea about what this will sound like? Otherwise i would install the Quart amp I bought for the sub, the sticking point being the lack of space for a component amp, with just the quart amp/sub I already have 1/2 the trunk space. this has me a bit nervous i must say.

That is a bad idea.  Ask him how he plans to cross over the subwoofers.

DYohn, I think I mentioned in my original post, there's only one sub, a Quart 12" if that effects your opinion at all. The RF amp has a built in sub crossover with a remote. I agree that this is proably not the greatest idea. I am trying to make it work with the space I have, you know?

The Alpine 9847 has a pretty good built-in amplifier.  If you have to stick with the gear you list, I'd power the Polk's off the head unit and use the amp only for the sub.  Trying to do anyting else is really asking for trouble, as long as you cannot go for a 5- or 6-channel amp as suggested earlier.Support the12volt.com

Thanks DYohn, I considered going head unit to the cabin and amp to the sub. I don't have to stick with the gear I have though, so I am open to suggestions. all my stuff is still under the 30 day return policy.
