Clif Designs CDX20A install help
Well, Ive got the amp in with an extra Optima red top switched by a Stinger Relay.
I dont think I'll be getting enough power to the amp. Im running it at 2ohm, using 2 Alpine Type-X subs. Im starting to think it was a mistake buying this amp and should get sumthing a little less 'greedy'. |
2 ohm with two batteries will be fine.

Just so everyone else knows. this is a 17v amp ;)
http://www.dynamicsoundcaraudio.net/item.cfm?product_id=51 I have never played with a 17v amp, so I don't know how much power they really need. I'd just hate to have it, cause my alt already hates my amp. 1200rms amp running at 1ohm + 4 black light tubes + head lights + the rest of the stereo = Volts dropping below 12. And this is while the car is running :P |

Even the page you posted a link to shows the ratings for 14.4v.... sure, it won't put out as much power, so the specs are weaker but it's not a problem to run it on a standard 12/14v system. |

As for your voltage dropping below 12v. have you done the "big three" ? Do you have a capacitor ?
|
Thanks for the help guys!!
Whats 'The Big 3'?? :dunno: |
Upgrading your alt, ground to engine, and ground to frame wire to 4 gauge or better.
|
basically, the theory behind the "big 3" is if a device is drawing current through a certain size conducter, the return path should be the same size. As trojan said; upgrade the battery negative to chassis, the alternator positive to the battery and you will have to add a wire from the alternator to the chassis. This should be done with same size gauge wire you're using from your battery positive to amp...

Oh, I see :thumbsup:
Well, the car comes stock with 2 batterries that are mounted on either side of the trunk. The ground is parallel between the 2 batteries and ground at the back of the trunk. I have the CDX20A isolated with an extra battery and grounded to the same common grounding point via 0 gauge wires. The Alt puts out 170, but I dont know of any upgrades that will work with the car. Has VERY sensitive electronics that I dont want to mess with :( The only thing running off the stock electrical system is a 7" LCD. Everything else runs on the Aux battery. http://www.msemerald.com/hin06/5hin06.jpg I may just go with a smaller amp :dunno: |
