  1. When you say really fast how fast are we talking about? Read post #7 below and check all the things listed. Also are you sure that it's bare metal that your grounded to, just asking because I have seen people sand down to the gray primer and thought it was metal.
  2. If you are planning on leaving it permanently installed I don't see any reason why you couldn't. The alligator clips are just a means of temporary connection, if you will be leaving it installed the ring terminals will be your permanent connection and serve the same purpose of delivering current to your batteries.
  3. Well if you are doing the DMM method using the calculations of 2ohm x 1500 = 3000. Then the square root of that is around 54 volts AC. Keep in mind though that rockford's amps are underrated so it is probably putting out around 1800 - over 2K watts. There a video of one being tested that put out 2235 watts. https://www.youtube.com/watch?v=VKO_sWLsMhs
  4. I will help as much as I can, to keep it short I will only reply to the setting that you have questions about. 1-2 Input Level : 0.5 - 8.5V (0db - -24db (i head unit is 4V what show this be set at?) This is used to match the input of the amp with the output of the head unit. The easiest way is to use a SMD DD1, next is an oscope, and if you don't have either you can use a DMM set them conservatively. Do a search plenty of youtube videos on this. 1-3 Gain Factor : Adjustment range: 0dB/+6dB/+9dB (is this bass boast??) I would not mess with this it will boost the signal and could lead to clipping, just set the input level appropriately. 2-2 Frequency : Adjustment range: 30 – 200Hz (1/12 oct. step) (what is a good starting point to set this? I have two 10 inch subs) Most people set this to 80 - 100Hz. 3-2 Frequency : Adjustment Range: 15Hz – 50Hz (5Hz step) (where to set this?) If you have a ported enclosure just set it a few Hz below the tuning frequency. 4-1 Parametric EQ On\Off (what is this and what does it do?) You more than likely can leave this off an amp because you can do more harm than good if you don't know what you're doing so this care of the entire section 4. 5-1 Bass Compensation On\Off (this does what?) Leave this off also it can lead to clipping, it's basically a bass boost.
  5. The amps are staying on because whatever you are using as a remote wire is not truly a accessory wire and it has constant power all the time. The radio staying on is a little strange because you said that you are using the factory radio meaning that all connections to the radio are supplied from factory wiring. What all did you add or wire up?
  6. Are you asking what will the bad battery do to charging voltage while running? If so the voltage will still show normal when the alternator is charging even with a bad battery. I had a similar situation with my camry where the battery up front went bad, didn't know because the rear bank was a lot bigger and disguising the problem. Found out when I tried to use the front battery to start another car. Have you did a parasitic drain test to see how many amps are coming out of the battery when everything is shut off?
  7. I am surprised you were able to get a alternator that big for that camry. I have a 270a from DC power on my 1994 camry with a 2.2 liter engine.
  8. Thanks for all the replies. I emailed a few shops today, just didn't know which ones were actually good and knowledgeable being that I'm new here or what a good price would be. I will also try craigslist.
  9. I actually would try to build it myself but I just moved here a couple months ago so staying in an apartment complex. That being said I don't have the resources or space to build one.
  10. Also how big should I be looking to make this enclosure to play loud and low for the space and equipment that i have? I will only have 450 Wrms going to it and it's rated at 500 so it won't be overpowered. Sundown recommends 1 ft^3 at 32HZ with a port area of 16 in^2 for it but I see some people make enclosures smaller or larger depending on needs and power.
  11. Now I wish I would have posted this last week because I was just in Vegas over the weekend for my brothers birthday.
  12. Thanks for replying, I had no idea shipping was that expensive. I live in Tempe, AZ which which is right outside of Phoenix. I have prius so driving is cheap for me.
  13. Hi all, I have been a member for a few years but this is only my second time posting but I need a sub box built. I need a ported 10" box for one sundown E10 V.3. Is there somewhere on here that can build a box for a decent price?
  14. Well my 270xp from dc came in last week. I haven't installed it yet because I have been out of town. I have compared it to my stock alternator and everything seems to match up but the dc pulley has 6 grooves and my stock has 5 grooves. I called dc and the rep said that I could just put the belt on the inner 5 grooves of the pulley and I would have no problem. I trust the rep I just need confirmation from experienced people on this site.
