Question about Alpine MRV-T757 Car Audio Amplifier

Ive had the amp for a few months now pushing 2 12" solobaric kickers. I noticed this morning that it is making my lights dim when the bass hits. Im thinking i need a capacitor, but i dont know how big i need or how much power the amp is actually pushing out. can anybody help me out?

Just get about a 1 farad capacitor. The only problem with this is, now your alternator will be under unwanted stress and will more than likely go bad ove time. With a stock alternator it is likely to not be made for that much power. The problem is, that now, it doesnt just have to keep the battery charged, but it also has to keep the capacitor charged.

Move all the grounds to chassis grounds of the van. There's more metal there to make a clean connection than to the wire you're using. If it sounds good now, enjoy it. Likely will be a very small change in performance unless your're running out of current on the big, sustained bass sections. If so, add a second capacitor ran in series and possibly a second deep cycle battery. There will be a point that your alternator can't keep up with the draw. Then you're gonna spend some money!

800w sony amp


I know i had a similar problem in my car, i ended up needing to do a battery relocation to the boot and putting a bigger battery in. Dont forget that just because the physical size is big doesnt mean it it has the amps so read the battery!

Bass sounds muddy and volume is minimum.


Hello mercedesman4,

Your setup sounds great. I had to settle for Blaupunkt in my Mercedes.

It sounds like the culprit is your enclosure. It's possible that by tweaking the settings, you could improve the sound somewhat, but having been used to the sound of a sealed enclosure, maybe not. Sealed enclosures tend to produce tighter, more accurate bass and have a flatter frequency response curve. They are also generally the enclosure of choice when looking for a SQ (sound quality) oriented setup.

Ported enclosures will produce louder bass than sealed enclosures, and maybe that's why some audio guys push them. They also allow the speaker to operate more efficiently, so you need less amp power for a given volume. Higher tuning on a ported box will get louder, but at the expense of sound quality. Lower tuning will still get louder than a sealed box, and the sound quality will be better than a box tuned higher, but still not as good as sealed. That's what I meant about tweaking the settings. You may see some improvement by setting the crossover lower, decreasing bass boost, or by turning the subsonic filter on/off. I'm no audiophile, but personally I've never been able to stand the sound of a ported enclosure, however it was tuned. Sealed just sounds better.

Hope this helps.

Green light turns red on hard notes with kicker 750 mono amp


First off, never, ever replace a blown fuse with a bigger one (especially one that is almost twice as big) unless it's an absolute emergency. Most of the time, the reason a fuse blows is because of a problem with the device (in this case, the amp). By installing a larger fuse, there's a very good chance the problem will become permanent (i.e. busted amp).

The amp could be going into an overcurrent mode when the bass hits and power cycling itself to try and reset the problem. If this is the case, take it to a local electronics repair shop and see what they can do.

It's also possible the input voltage to the amp is dropping too low during the bass hit, making the amp restart. Try putting a 1.0F or higher capacitor on the battery to buffer the power during the bass hits.

Craking sound


its either a bad voice coil or your amp is under powered while hitting good bass, could try a CAP or replace your car battery

Kickers dont beat like they should


try to check and clean the wiring as clean as possible to avoid messing up on your connection. Check the polarity of you subs to yuor amp if you have it connected on the outher way around it would not give you a good result. check the polarity this will solve your problem. Over powering your sub will fry it easily try to tune it a 10" sub wont give you a 15" performance..

I plugged int he rca's but he the lowest sounding bass possibe


kicker subs arnt ment to hit the lowest bass, unless you go spend a **** load of money, im talking 3000 wat amp, ant some 15' or bigger subs. the most commen kickers are 12' subs, so im asuming you have 12' subs, if not, this (said lightly) should work. try turning the bass boost screw on the amp to the middle of its turning range. this will offer the greatest balance between high and low bass. if you want more low bass, turn it past half. if you want more high bass, turn it down. i have mine set to mid range, but i also recently purchased 2 18' kickers. with every new set of subs, you should spend at least 15 min tuning the amp to get the best performance. every sub is different. hope this helps, good luck.
