Question about Car Audio & Video

I think its an off brand amp and im not sure if that really is the peak but how off could it really be? I like the sound of the amp and sub but i want to get full power but i know that i need a new box. But if you have anymore information that will be very helpful because i have never heard of this amp but i paid $450 for it and im hoping that i can get the real power i need. Thanks for ur help so far.

Hello dwayne93702,

I would suggest that you take this to your local auto-sound shop to have this done, however here is a procedure that has worked for me in the past. (It is tedious, but it allows you to develop an excellent chart showing relationship between frequency and power and helps you know the frequency limitations of your amp.

If you are trying to get the full range of power then I would suggest doing what is called a load test. For this you will need to use high wattage power loads (high wattage resistive loads 8 ohms) connect these in place of your speakers and sub-woofer put the amp at full power and inject a 1000 Hz tone and then with an oscilloscope adjust the sine wave to 0 distortion and measure the output voltage (Peak to Peak) and then do this calculation to get the RMS voltage:
(P to P/ 2) x .707 = RMS
Use the RMS voltage divided by the resistance (8 ohms) to get your amperage (current value).
Then once you have your current use it multiplied by the RMS voltage to get your max Power without distortion.

This will give you a good indication of the max power you can get without distorting the signal. I use 1K Hz because it is a reference tone. basically you can do this test on the whole audio frequency spectrum for a more in-depth measurement (building a power response graph).

I hope this helps,

If i have a 4 channel 2000 watt amp, can i use 1600 watt wires if i only have 2 subs hooked up to it?


Yes, you will be fine. 4 gauge power wire is sufficient for a couple of reasons, the primary one being that most of the companies that are boasting 2000 watts for a 4 channel amp are off brand "web-retail only" companies, and they severely over rate the power output of their amplifiers. Secondly the supposed 2000 watts is peak power and not rms power. Peak power means how much power that amp can put out during absolue climax of the music or during a tone burst. RMS power is how much that amp will put out continously to your speakers or in this case, your subs. If you look at the spec sheet of that amp, in all actuallity you're probably only getting 200-300 watts rms even bridged.

On a side note, if you really want to push your subs hard, you might want to consider getting a mono block or "class d" amplifier and use that 4 channel amp to push your surround speakers. Class d/mono block amps are specifically designed to push subwoofers and will give you the most efficient power out and the best heat dissipation to withstand the output required to drive subwoofers. You'll get better bass and also more adjustability to tweak the sound levels coming out of your subs. Hope that helps.

I have a Punch 800a2 amp and tommorrow im getting the Polk Audio db1222. so my question is do i need a different amp or should this be sufficiant. 12" 2 Ohm db Series Subwoofer Power Handling: Peak:...


Not sure if you are getting two subs or single?

Anyways, amp is rated at 800 watts and probably under rated so it will push sub. Remember that you don't need to worry about max power, rather focus on RMS power rating.

I have a fairly good sound system in my jeep cherokee, new speakers, deck, new battery, rca cables, and a new box for my subs. But recently i've been dealing with some problems. i've had my amp grounded...


there are really only 2 causes for this.

  1. grounds. Make sure the grounds are clean and tight and all paint and dirt was removed before they were fastened.
  2. Your alternator is starting to go bad.
I would lean toward the grounding problem as you have said you just changed them. Also make sure the grounds are as short as possible.

What to do


well i don't know your budget, but if that's not really and issue, right now at best buy, alpine type E, 10" subs, peak is 750w and rms is 250w, each is 129.99. Alpine type R, 10" subs, peak is 1500w and rms is 500w, each is 199.99. These are the best subs i found at best buy. You could sell your current subwoofers and purchase those, and you'd save space and still get the lows you want. Goodluck

Knocking noise with my kicker compvr 15"


comp VR 15s are rated @ 500W RMS 1000Peak.
The lanzar vibe amplifier is 2 x 600W RMS at 4 OHMS 2 x 1200W MAX at 4 OHMS 1 x 2400W MAX at 4 OHMS Bridged 2 x 1000W at 2 OHMS RMS.
Your subs are single 4 ohm subs.
If your subs are wired stereo, they both are seeing 600W. (more than the rated RMS)
Chances are, you have them wired parallel to a 2 ohm mono load - of which that amplifier is not rated. In theory, it will produce about 2000W @ 2 ohm mono for a short period of time.
Your amplifier is too powerful for your subs. Turn down the gain setting to 3/4 or purchase better subs. Also be sur the subs are inthe proper enclosure. It sounds as if they are excurting past their linear x-max and colliding with the rear bump plate. This will cause damage down the road if left as is.

How to order


The L7 I have is brand new in the box (not a speaker box just the retail packaging box) and the rms is 750 watts RMS and 1500 watts peak, but you are correct they blow easy when you push rated power to them, the hifonics subs will take 1200 watts rms all day long and over 3500 peak for burping at competitions, i run mine at 2000 watts everyday in a daily driver. if you hook 1 dual 4 ohm sub to a zx1000.1 it will be 2 ohm load on the amp so you will get 1000 watts to the sub so if you want to run it slightly underpowered to keep it from blowing use the 750.1 per sub, i can do those at about 250 each shipped

the price is 150 plus 10$ flat rate USPS shipping and yes I accept paypal Wyattconnolly@msn.com .

the warranty starts the day you buy it for 12 months but kicker will not cover burned or blown voice coils, that is why i recommended the hifonics (which is what i use to compete with now) because they put out better quality sound and alot more of it and they will take alot of abuse, if you want boxed speakers ready to go in kicker brand ported boxes I can have them drop shipped right to your door as well, the only reason i am selling the 1 L7 i have so cheap is because a customer ordered it then never paid for it so I am selling it at cost. be careful if you are buying on ebay as you have no warranty at all and you cant force the seller to give you 1 even if they say it has 1. because authorized dealers are not allowed to do internet sales at all so kicker and most other companies will not honor the warranties.

also you dont need 2 amps you can use 1 bigger amp and still run 2 subs just by changing how you wire the subs at the amp. 1 large amp costs less than 2 smaller 1's usually just not with kicker brand

Make sure that you have the subs wired in a 4-ohm series and not a 8-ohm load
