Power caps??

hi,

i am going to be running a 300w 2-channel amp with a set of matching 6x9s, as well as 2 600w 4-channel amps. One will be running 2 sets of 6x9s and the other a 12" sub and a set of components in my GP. It is all running of a Pioneer head unit. Does anyone know if I will need a power cap? If so what type would you reccomend?

Thanks

No they dont do anything!!!!!! your better off Upgrading the battery and alternator. Can i ask YTF are you using three sets of 6x9's before you waste your money on a system like that i would do some research and ask a few more questions because you will be very disapointed with what you are suggesting.

what do you suggest i do then??

Avoid 6x9's like the plague, I suppose. Where on earth are you gonna stick them all? are you replacing the stock speakers or leaving those in too?

i have rep the stock speakers already, front with comp an rear with full range speakers. Gonna buld an enclosure in the boot for me amps sub etc....

Also do you reackon that your alpine HU has 5 sets of preouts as that is how many you will need. They can probably be split using the outputs on the amps but you will be making a crap system even worse by splitting the level of the signal that the amp recieves, and also it will make set up a little harder as the Gains will all have to be different but thats not that much of an issue.
The first place that i would start is by saying that it can be pretty difficult to set up an amp with components and a sub running off of it if you dont have seperate level setting for both parts of the amp.
Now that you have introduced a sub into the system you will not need any 6x9's their sole purpose is a way of creating cheap bass for cars that dont have sub's so they will be completly useless.
My advice is
300w 2 channel= Rear components
600w 4 channel= bridged 2 subs
600w 4 channel= Bridged Front components

This is only a provisional guide it would be nice to know the exact spec of what you have and weather you have the stuff already then i can help you more.

its a pioneer HU
i have the 2 channel amp and one sub

Right then amp up the speakers that you have already then. full range speakers in the boot will be useless unless you are building a show car and you wont get any respect from having 6x9's in there at that kind of level you are talking about building enclosures in the door lining of the boot which is hard work but dooable.

Technically he could use a line driver to boost & split one of those pre-outs into about four. You can pick them up on eBay for cheap if you're careful, too.

I wouldn't stick a million speakers in my car. I just replaced the stock ones and amped those up, and of course stuffed woofer goodness in the boot; its far beyond "loud enough".

what 4 channel amps would you recommend to get?

power caps do work. they hold a charge from the battery and when the bass drops its takes the extra power from the cap to avoid damage to your electrics. i had two power caps and also a split charge battery system but then again running 4000watts

But if you are looking into line drivers then the money would be better off spent getting the right amps and speakers. Also like anything you get what you pay for and a lot just amplify the signal and you only get out the number of preouts that you put in.

Cheap and still not enough Prouts.

Yes but you have to capacitate 1 Farad to every 40w RMS to have any effect my system is roughly 2kw which is about average so i would need 50 Farad power cap and you will not get a 50 farad cap for under £400 also the Alternator could not distribute the power enough to make any difference. You are better off running a Relay to a second battery in a boot and upgrading the alternator.

decided to downsize a bit. gona run 2 subs, each off a mono amp an run my comps a 4 channel amp

You are better of buying 1 good Mono amp and wiring the two subs together at 2 ohms or even 1 ohm if possible therefore you get more power and space for less money. What is your budget and i can give you a few pointers on what to buy.
