suggestions for high efficient amp for obsidian 15 D2.

i figure ill get my tax return and get a new box. double baffled, 27hertz. 3.5 cubes. carpeted and lettering on it. so that'll eat up the tax return. $150-$200 then I'm getting $110 for my old sub. plus maybe putting $40 bucks a month towards it. so it'll take me like 11 months to have the money for a mechman... **** lol... other alt companies are cheaper tho? and also make an exact fit model?

i have tons of places to get honda drop in alts. and more affordable than mechman. ive installed 4 and they are still going and putting out their rated

Yeah but the AP requires 14.4v just to run properly without clipping and if it's ****** as you claim that makes matters even worse... Chances are hes clipping like crazy if he drops anywhere below 14v and is tuned for the amplifiers full power You also didn't factor that he is PROBABLY running a 4 channel as well. A battery IS a bandaid and I can vouch this considering I have a similar setup with an EFFICIENT amplifier and I still have killed alternators. If this guy tried running at .5 ohm hes just asking for trouble and dimming will be the least of his problems.
Dude simply invest in a battery I ran the aP1500.1D and while it's not the greatest amplifier it gets the job done. No 1200w amplifier is going to stop dimming now matter how efficient if you don't have decent electrical to back it. Like I said I run big 3 a good batt and 0 gauge with a good amplifier and I still get drop and dimming, before the battery it was way worse.

Even without clipping, on a better electrical using 1500 watts, I was never above 14v. With music you're not going to stay at 14.4v or without a really really good electrical. If you are still getting dimming, then your electrical still cannot support your amp. There should be NO dimming at all, if you're dimming, you are dropping below 12v which is BAD. You need a new alternator if you are still getting those problems with the big 3 plus another battery.

Op do not listen to this stupid *** post. You should NOT be dimming PERIOD. I ran 1500w on 140 amp alternator with 2 ga wiring (stock wiring) and i had no dimming problems. You need a better alternator. Your problems are not going to go away unless you address the issue by starting here.

I would also say check all your wiring connections. A bad connection and/or a poor ground can cause these issues as well.

As for what Tony is saying. Sorry, but he is wrong in this case.

I'm running a 2 channel comp amp and the comps only take 110 outta the 600 that the amp can do. the apsm can only take up to 4 awg so i have knu running through my car. best i can rele do with this set up. other than adding batteries, eld bypass, and a new alt... and i don't think i have the apsm set to run on full voltage. i don't think my system is clipping. and sounds pretty good. just wish i had the electrical to get the oa what it wants.. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

it could just be a bad alt too. he needs to check that. and depending on the year/model it also may not have an ELD bypass.

im all for a new alt but it really is not worth investing in unless he is going to run more power.

You do understand that even when adding a 500 watt amp you should upgrade the alt correct? We never do because we can get by with out it, however, it should actually be done.

Damnit dude...this has already been solved for you! Its the ELD thing that is keeping your voltage down... A different amp isnt going to solve your problem!

 

[Mr.meyhem 10+ year member]

Ok what is your voltage drop in the first place. ? also what year/model civic do you have.

idk the voltage drop to be specific. ik its dropping tho there is no stock volt meter so i have one on the way here now. its an 09 honda civic lx coupe. 8th generation.

stock 105a alt redtop starter and hc2000 running an mb quart 4.60 at 2 ohms (120x4) and an mb quart 1500 maxxed out at 1 ohm (1500x1)

looks stable to me

Well he can't even support his system as it stands right now. He needs to upgrade his electrical for his current system before he even thinks about adding more power.

okay just got through reading everything lol. by the time i reply there r 10 more posts. (thanks for the help btw) so what you guys are saying is go for a new alt and the eld bypass. if dimming still occurs add a batt.

 

[pro-rabbit 5,000+ posts]

Every application is different. Basing your idea off of what will "fix" the issue from what others have had "work" is not offering help at all.

OP-If you car is limiting your voltage then you need bypass that in some way. Scions are horrible at this as well, but it can be bypassed or adjusted depending on how yours is setup.

I would do the bypass first. It will net the best results for the money at this time. See where you are at that time, then look into an alt if you still have issues. The other option would be to do the bypass and upgrade your front battery. That combo should help out a bit. Then upgrade your alt later on.

its an acura...acura=honda

all he needs for the bypass is an 820 ohm resistor and a screwdriver lol...its real easy to do
