You need to match your amp's input voltage (the gain) to the output voltage supplied via your deck's preouts. Turn you radio up to normal listening level, and turn the amp's gain until you induce audible distortion then back it off slightly. Set the bass boost and crossovers to on and type (highpass for front/rear full range or lowpass for subs).

I have a 12" d4 type r 1000 rms and a alpine 1000 amp speaker sounds great but smells like something is burning, my amp never over heats or shuts down but the smell is still coming from the sub?


Cut your gain back on the amp. It sounds like they are set too high. Check your install instructions on how to set your gain. If you have a 4 or 5 volt output head unit your will not be at half way. Im running a JL Audio 500 /1 on a skar wwv10 dvc in a ported box. My gain is set about half way & its plenty loud.I have a Alpine 9887 headunit 5 volt output on my RCAsI can take a volt meter & set my speaker output at 45amps & my gain in perfect.

Have 4 - 12 alpine type R in custom box made just for them. Hooked up to a JL 1000 slash 1v2 mono. They all have power but when i really crank it one of them pops a little. Theres no way that amp could be...


It may not necessarily be pushing the subs to the blowing point, but you amp may be clipping. If you amp reaches a certain point where is strains for power, it cannot reproduce the frequency. The result is a "popping" sound. Your right in that the amp couldn't be doing that. Another thing to check is what is the ohm load on the amp. Is the amp 2 ohm or 1 ohm stable. You could be damaging the amp if it is not wired correctly. Hope this helps.

What size amp do i need to run 4 1000 watt pyle 10's bridged


well first of all you cant bridge subs... you can bridge an amp... and for 2 they are probablly not 1000 watts, make sure you understand RMS and what the sub can ACTUALLY HANDLE properly... i would get a 1000 to 1500 watt RMS that is RMS RMS RMS RMS amp not one that says 2000 watts MAX POWER cuz thats cheap ****... get a kicker JL hifonic alpine or something in that category that actually tells you the TRUE power output of the amp... then run those 4 subs in a parallel circuit so its like really only having 2 subs. make sure then these subs do not run less then 2 ohms at the terminals while in a parallel, then bridge these subs acting as 2 subs not 4 to your TRUE 1000 watt amp and you should have a good powerful system

4ohm dual VC alpine x sub is actually 3ohm DVC i blew my 2 seperate JL audio g-max 1200w amps. what should i do with these subs?(i have 2) is there any amp that can put out 1000rms+ at a 3ohm load per sub?


Well if it is not dual 4 ohm, i have never heard of a sub with dual 3 ohms. There must be something wrong with the voice coils and if that is not it, I dont know.

NOT SURE WHAT OHMS SUB I NEED!


if you get the 4ohm you can wire it to run a 2ohm an the kenwood amp will push 900 watts at 2ohms.they say it can push up to 1800 watts,that would be at 1ohm.that kenwood runs 500 at 4ohms an 900 at 2ohm.if you need help wiring the sub or anything else let me know bertman285@hotmail,com Max Power Output 1800W Power Output 4 Ohm [14.4V] 500W x 1 [20-200Hz, 0.5%THD] 2 Ohm [14.4V] 900W x 1 [100Hz, 1.1%THD] Bridged[4 Ohm] -

Alpine in dash tv issue


this is the problem with the additional battery wiring. use appropriate cutout and do rewiring. make sure the Dynamo has the enough capacity to charge both the batteries. better avoid using your music system till the problem is rectified.

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

I have a jl audio 12w7 with a 750/1 hd amp and i want more bass is there anything else i could do to get more out of my sub. i was told to add a battery and another amp to my deck speakers will that help...


My full time job is designing and building sub enclosures. So you are in luck.
Anyway you don't want deck speakers and amp for more bass and adding a battery doesn't help unless you already have power problems. Adding an amp and a sub would help but can be expensive. My main recommendation would be to change the box your sub is in, designing it for your vehicle. If you are in need of bass that is crazy loud, then you would be adding subs and amps. Your amp can drive a bunch of subs if you want and it would probably be more economical to just add a sub or three. Shoot me an Email @ dynami28@charter.net if you need specifications on adding such improvements.

Alpine type-r 2ohm dual voice coil help


try reconnecting your rca's from the deck to the amp when finished wire one speaker positive to positive on left channel and negative to negative on right channel then connect the 1st subwoofer. if all power and sound is fine and working turn off power to amp and connect negative terminal of 1st sub to positive on 2nd sub and positive from first sub to negative on second crossing the wires runs the speakers in series another way to try is parralel the speakers wiring by connecting positive left channel output of amp to positive on 1st sub same with the negative then splice positive to positive on second sub and same with negative.
