i bought 2 kicker solobarice 10" subs, and a dual chamber box, was all pumped thinking i'm gonna install this weekend, but, all i have is a kenwood 800w, with 460rms, and each sub can take 450 rms...so, i thinx i need another amp for the other sub?, how is that going to go over as far as the battery, is it gonna drain the "eff" outta it?
i dont want to push the subs at half power off the one amp, and soem guy told me it'd be bad for the subs anyways???

school the car audio newb.

You need to mention the amperage of the amp. It's prolly in the neiborhood of 40Amps. Most likely, another amp that size will be pushing it, as our civics have an excess of about 50Amps (from what I've heard). A capacitor might help.

BTW: It's hard to believe that your 10" subs will sound bad with 200-400W through each of them. You won't damage them with that amp. Your sound guy wants to make some money.

amperage? the kennywood, had two 30 amp fuses on it..i can pull up the full specs if ti will help...

guy said i'd be gettin 235 to each sub....i'm so green i suck...

you need to check the ohms on ur subs and if they're SVC or DVC, u might not be able to run the amp on one sub cause ur ohm loads need to match..

you could run the 1 amp on 2 subs, it wont be giving them their potential, but it will work..

dvc kicker s10L5, 4 ohms each

OK. Ya. That is a fairly weak amp for those subs. Hmm...you can still use it, but that amp is not 800W for all practical purposes.

well, spose get another just like it and run each to a sub...then comes the power issue...maybe i'll just run one sub for now until then??

That's a good idea, if you can afford it. Bridging each one will pump 400W to each sub. That's a healthy amount of power. I would buy a capacitor (expect to spend at least a bill for a good one) to keep your subs from bottoming out at hard bass hits. With a decent capacitor, you should be ok, as long as you don't want to run at high volume with your engine off or at idle for a long time.

Someone should back me up on the excess power of our alternators. I heard 50-60Amps, but I could be a little off.

no, no worries about running with engine off, its only for the friggin daily hour commute, and to drown out the ***** other people blast.

good cap recommendation? i want one anyways, they're so...cute.

bahahahaha

CPCD10-03 by rockford? looks to cost about a bill.
1 farad, cuz i'm only really gonna be running about 900ish on the rms.

you need to know the impendence of the amp before you screw anything up........either a 2 channel bridged or a 1 ohm stable mono......

and dont worry about a compacitor.... does nothing but increase that hole in your wallet...

No, a cap is good for one thing, and one thing only, that is to combat dimming. If you're not worried about your lights dimming, then I wouldn't worry about it. As for the stock electrical being able to handle both of those amps, it'll run them just fine. There are people here pulling double that power off of the stock electrical.

its a 2 channel....thanks a effin ton guys! been trying to figure this out, but i am pretty new to this stuff, its not as simple as yu first think, then, it gets clearer, thx a mill!


edit: the bloddy thing will be bridged, but, until then i needta get another amp for the other sub, as it might be kinda gutless as i would end up running both kickers off the one amp..both only get 230rms, abotu half what they max at....

I think you should give it a shot. Your not going to blow your subs the instant you try running both of them.

You should be perfectly fine. The reason subs blow when they're underpowered is that people commonly turn their Gains up high, then try blast their music loudly as well, louder than the amplifier can power. In this case, the signal starts to clip, and then the subs get pissed and go out on you. If you hear your subs distorting, turn it down, or your subs will fry.

If you go try it, and decide it gets loud enough for your use, then I wouldn't worry about getting another amp too much, just be careful when trying to show off with it.

Just check your gains, any bass boost on the amp or your headunit and your volume level and you should be alright.

One last thing, I just checked that dual sub enclosure you posted a day back, it seems to be separated, which is good, in case you do decide to try run just one of your subs.

Just in case you decided to go with another box, and does not have a divider between the subs, sharing the airspace, I'd reccommend not judging the sound quiality quite yet. Between the doubled air space, and the second sub acting like a sort of passive radiator, it won't quite sound right.

Also, be careful with all that power and one sub. It's not really a big deal, but with the lack of proper suspension, you chance over excursion, again, probably not an issue.

If you got that box you posted before, with two separated airspaces, ignore this post entirely

yeah dude, i went with a box from ikesound.com, dual chamber, but, another thing, its for the right subs, but, it says the cu.ft is 1.21 per chamber, L5's max should be 1.0, so, i guess i gotta toss something in to fill the excess? also, whats yu figure i should to to wire em up? series , parralel, or wtf? i dunno what to do, i'm feeling dumb and numb, then again, its pretty frickin late....bla bla..............thanks to everyone for your help, keep it coming, haha.....

well if u buy another amp man the 2 channel would be useless unless you want to run the dvc ohm into an 8 ohm load which would be worthless imo....... maybe if you buy a bigger 2 channel.... less wiring for you and less stress...

Two channel is fine, he can bridge the channels for mono use.

Here's the best way for wiring it up right now:

Series the voice coils on each driver, resulting in 8 ohms/driver, then parallel each driver, for 4 ohms mono, connect that up to the sub, bridged for 460x1, each sub will get 230 watts.

I honestly think that might be enough bass for you now. Give it a try, if it's not loud enough before it distorts, you're golden.
